GoodReader Troubleshooting: Transferring Files

WiFi File Transfer doesn't work
In case of trouble with WiFi file transfer, please try to do the following:

  • Make sure you've updated your computer operating system to the most recent version
  • Restart your iPhone/iPad (power off, wait 10 seconds, power on again), restart your computer, and restart your WiFi-router (power off, wait 10 seconds, power on again)
  • make sure that WiFi-signal strength is at maximum on both on your iPhone/iPad and on your computer
  • don't use Bonjour-address from WiFi-transfer page, for Troubleshooting purposes use IP-address only
  • if your computer is a Windows-based one, delete all previously created network shortcuts that you used for previous connection attempts
  • temporarily disable all anti-virus and firewall software of your computer
  • make sure that your iPhone/iPad and your computer are connected to the same WiFi-network. This is very important. Your computer must be connected to your WiFi-router wirelessly, not via cable.
  • make sure that you're entering the correct IP-address from GoodReader's WiFi-transfer page, with http:/ and :8080 parts. IP-address may change from time to time. Please do NOT assume that it's the same as it was when you were connecting the last time.
  • make sure that you keep GoodReader's WiFi-transfer page open all the time while connecting
  • some WiFi-routers, while allowing Internet access to each device, may prevent peer-to-peer communication between connected devices on the network. Check if it's the case with your WiFi network. Depending on an actual router model, you may want to look for some setting like L2 Isolation, Layer 2 Isolation, or any other isolation.

If you're trying to connect to a Windows PC, you may experience errors due to Windows operating system bugs—depending on what version it is.

To check if it's a Windows bug and not a network setup problem, try to use AnyClient for file transfer - free and very convenient client application that can be downloaded for free at www.anyclient.com web-site. When setting AnyClient connection, select WebDAV in the Connection type field, and enter the full IP-address (with http:/ and :8080 parts) in the Host field.

If all of this doesn't help, please contact our customer support service. Please provide the following information:



  • which operating system is on your desktop computer?
  • describe your network setup - do you connect your iPhone and your computer to a WiFi-router, or is your network created directly from your computer, without any router?
  • if you use WiFi-router, is it your own or is it some wireless public access point?
  • is your computer connected to your router wirelessly or via a wire?
  • did a red label flash on GoodReader's WiFi-transfer page while you were trying to connect?
  • which error messages, if any, did you see both on your iPhone and on your desktop computer?

I use GoodReader's built-in web-browser and some links don't work when I tap them
GoodReader uses a very simple built-in web-browser — much simpler than Safari. Some websites may have links that use pop-up windows or certain types of JavaScript code, which cannot be opened or detected by this browser. In these cases, try this workaround.

Tap the link and hold it for a while. System menu will pop up with the choice of actions. Select Open action. The link should open. If it doesn't open, select Copy (this will copy the URL address to clipboard) and then press Follow the Link from Clipboard button:
I want to stop syncing a file or a folder, but can't delete the corresponding sync record
To stop synchronizing (unsync) a local file or a folder, you have to delete its corresponding sync record. Tap Connect, tap Sync Records, then use the Trash button to delete the sync record.
When connecting to a shared Windows folder, GoodReader is always denied access and is asking for a password, but I don't have a password set up on my Windows machine
It may be necessary to adjust the Advanced Sharing Settings on your Windows machine, however, the steps to do that may vary depending on your Windows operating system version. In general, here's what to look for. Open Network and Sharing Center, and click Change advanced sharing settings. Find the Password protected sharing section and select the Turn off password protected sharing option. Alternatively, a more secure solution would be to actually set up a password for your Windows user account.
Troubleshooting: Viewing PDF files
I cannot close a file, because navigation menu has disappeared
When reading a file, the navigation menu automatically hides after about 7 seconds to give you more reading space. To bring the menu back, tap the center of the screen once with one finger (this applies to any file type).

When reading PDF files, if you tap on a link, that will take you to the link destination, rather than bringing the menu back. As an alternative, tap the screen once with three fingers. This will make the menu appear again and will not trigger any links (works with PDF files only).
I can't select a text to copy or to highlight it
Tapping and holding on text in a PDF will select it if that text is selectable. If you can't select or highlight text, that could mean the text is only a scanned image of text, or it could mean that the PDF file is copy protected—making it impossible to copy text from that file. To highlight text on a scanned, image-based document, try using the Freehand Drawing tool, and change the Opacity level to 75%, 50%, or 25% to simulate a highlighter tool.

I accidentally highlighted a text, but can't find a way to remove a highlight
To invoke annotation-specific actions (deletion, color change, etc.), tap a highlight/markup briefly to bring up the menu, which includes a Delete button. Keep in mind that it is possible to apply multiple highlights to the same text, so in some cases you may need to repeat the deletion process to remove each instance of a highlight.
I annotated a PDF file, emailed it to someone else's iPhone/iPad, but that person can't see my annotations in Mail app
PDF annotations made with GoodReader are only visible in applications that offer explicit support for PDF annotation, such as Adobe Acrobat or the Preview application on a Mac. Other software such as E-mail client applications (Mail or Outlook) may not be able to display annotations. Try opening the PDF file in a PDF Reader app to view GoodReader annotations.


Alternatively, GoodReader offers the ability to "Flatten" an annotated file. During this process GoodReader embeds all PDF annotations into the main PDF page body, making them a part of a normal graphical page content. This results in two things: 1) any app that can open a PDF file will display the flattened annotations, 2) all your annotations become non-editable — because they're not truly annotations anymore, they've become graphic elements in the PDF page itself. This may also be useful if you want to prevent your annotations from being edited by someone else.


The Flatten option will be offered to you every time you try to send the file from GoodReader via e-mail, or any other option via the "Share" button. It is also available as a separate Flatten Copy command when viewing a PDF file and using the Actions button in the bottom right corner of the screen.


GoodReader can offer the chance to "unflatten" a flattened file after sending it if the recipient uses GoodReader to view that file. This option must be explicitly enabled in GoodReader's settings (Settings - PDF Options - "Unflattening is allowed") before the Flatten command is used. The default setting is not to allow unflattening, to prevent your annotations from being edited by someone else. Please also note that if a recipient somehow edits a flattened file before unflattening it (by adding new annotations, for instance), the ability to unflatten previous annotations is lost.


My PDF takes extremely long time to open or to render a page
While recent model iPads and iPhones have become more powerful, their processing power is still relatively slow when compared to desktop and laptop computers. The PDF file format can be very complex, allowing for its internal data to be formatted in a variety of ways, depending on the software that created it. Some PDF files may open instantly and pages will turn very quickly on a computer, but are not well optimized for mobile devices like iPads and iPhones.


Try optimizing your PDF before transferring it to GoodReader. On a Mac, open the file in the Preview application, then use Save As to make a new copy of that file — the result should be more friendly for iPads and iPhones. On a Windows PC, try using whatever PDF creation software you have available to create a new copy of the PDF file that is optimized for mobile device reading.





Some characters (Asian, Arabic, special math symbols, etc.) in my PDFs are unreadable, but they appear correctly on my Mac/PC
The fonts for that particular PDF file may not be embedded into the PDF file itself. In that case, iOS automatically substitutes missing fonts, but the correct font may not be available in iOS.


Using a computer, try embedding fonts into the PDF file.


On a Mac, open the file in the Preview application, then use Save As to make a new copy of that file — the fonts should be embedded in the new PDF.


On a PC, open the file, then use the Print option to "Save as PDF", making sure the Embed All Fonts box is checked, and rename the file to create a new copy of that file.


As an alternative, use GoodReader's PDF Reflow option to view the file.


I see the text on my PDF page, but PDF Reflow feature doesn't show this text
The most probable reason is that you're seeing a scanned page. Please note that scanned page is not a textual information - it's a picture.

Modern PDF-creating software often includes the OCR (Optical Character Recognition) information when creating PDFs from scanned pages. In such cases PDF Reflow may show you a valid text, but that's not always the case, many scanned PDFs don't have any textual information.

I see the text on my PDF page, but PDF Find feature can't find it
Here are possible reasons for this:

  • the page is a scanned page. Please note that scanned page is not a textual information - it's a picture.
  • if your search string contains whitespaces, it may be the problem, because extracted text may contain no whitespaces or several whitespaces where there's just one in your search string. Try to avoid using whitespaces in search strings.
  • the text was not extracted correctly from a PDF page. Please note that correct extraction of pure text from a PDF page is not always possible. Use PDF Reflow feature to see how exactly the text was extracted. If you see that the text was extracted incorrectly, we encourage you to send this sample file to our customer support service for further examining. Extracting text from PDFs requires some heuristics, so we might come up with better extracting solution after studying your file.
I see the text on my PDF page, but PDF Reflow feature shows some unreadable characters instead of it
You may see a scanned page, and PDF Reflow may extract textual information provided by OCR (Optical Character Recognition) engine of PDF creating software. Optical Character Recognition engine sometimes produces strange character sequences when it's uncertain about which character exactly it sees.
My right-to-left reading PDF file (Hebrew, Arabic, etc.) is shown backwards in PDF Reflow mode
Some PDF files with right-to-left fonts instead of encoding text as they should - from right to left - actually contain text stored in left-to-right (i.e. reversed) order. GoodReader extracts text in the order as it appears in PDF file, which makes it look backwards in Reflow mode. We're still working on this issue. Please keep in mind that this problem is created by PDF creating software, which doesn't store text inside PDF in the correct order.



I see the text in my right-to-left reading PDF file (Hebrew, Arabic, etc.), but PDF Find feature can't find it, although it does find it if I enter it backwards
Some PDF files with right-to-left fonts actually contain characters stored in left-to-right (i.e. reversed) order. To be able to find text in such files, the search string must be entered backwards. Use the Flip search string switch in PDF section of Application Settings to enter search string in readable form, and it will be flipped backwards internally during the search.



GoodReader says that this PDF format is not recognized, but it shows fine on my Mac/PC
The file could get damaged during file transfer process. Please check the file size and see if it matches the size of the original file. In any case try to delete a file and reupload it to GoodReader.

If reuploading file doesn't help, we encourage you to send this sample file to our customer support service for further examining.

I often find myself making accidental double-taps, when I don't mean to
You can turn Double-tap for zooming option off in PDF section of Applications Settings. This option also controls the single tap with two fingers gesture for zooming out.
I'm unable to use Horizontal Scroll Lock feature, because the button is inaccessible (grayed out)
Horizontal Scroll Lock feature only makes sense when you do vertical page turns. Therefore it is automatically disabled when you either turn the Horizontal swipe option on in Application Settings, or when you select a double-page layout for a PDF file (selecting a double-page layout automatically turns horizontal page swiping on).
Troubleshooting: Viewing TXT files
I cannot close a file, because navigation menu has disappeared
When reading a file, the navigation menu automatically hides after about 7 seconds to give you more reading space. To bring the menu back, tap the center of the screen once with one finger (this applies to any file type).

My TXT file shows unreadable characters instead of a real text
The Text Encoding setting may be incorrect. When viewing a TXT file, tap the Settings button at the bottom of the screen to find Text Encoding settings.
Troubleshooting: Viewing other files
I cannot close a file, because navigation menu has disappeared
When reading a file, the navigation menu automatically hides after about 7 seconds to give you more reading space. To bring the menu back, tap the center of the screen once with one finger (this applies to any file type).


My MS Office files crash GoodReader
Unlike with PDF and TXT files, for which we've written our own viewers, we use iOS's built-in viewing engine for MS Office files. This engine may not able to open large MS Office files, or there may be difficulties MS Office files that contain features which are incompatible with iOS. An iOS update may be required to fix any MS Office compatibility issues, so make sure you've updated to the most recent iOS version. Otherwise, try converting your MS Office files to PDF format. Huge PDF files are not a problem for GoodReader.

My MS Office files are shown a little bit incorrectly - text is off-place, formatting is different, etc.

An alternative solution may be to convert your MS Office files to PDF format. In this case you will solve the incorrect appearance problem, plus you'll get the ability to use our Find Text in PDF files feature and other PDF-specific features, like PDF Annotations, Highlights and Markups.


Troubleshooting: Other Problems
I try to use the "Open In" or "Share" menu in another app to send a file to GoodReader, but I don't see GoodReader in the list of apps
This file transfer process is managed by iOS, so its functionality may vary depending on what iOS version you're using, and whether or not there are any iOS bugs in the current version yet to be fixed which relate to the process.


However, in general, it's only possible to send a file from another app that GoodReader actually supports (like .PDF, .TXT… etc.). If GoodReader doesn't support the file format, GoodReader won't appear as an option in the iOS Share Sheet. Keep in mind, if you're converting a file to PDF in the process of sending it to GoodReader (like saving a web page as PDF), GoodReader will not appear as an option in the Share Sheet because the file must be in PDF format before you attempt to send it to GoodReader.


It's also possible after an iOS update, that your iOS Share Sheet may reset to default app options. Consult with Apple Support about how to manage Share Sheet options for the iOS version you're using. In iOS 13, it's possible to add "Favorites" to the Share Sheet, which in some cases is the solution to ensuring that GoodReader appears when you want to send a file from another app.
GoodReader tried to open some file and crashed. Now I can't even start it, because it crashes every time trying to open that file on startup.
Open main device Settings, look for GoodReader settings there. Turn the Don't open anything switch on and restart GoodReader - this time it will not try to reopen the problematic file.
I forgot my app password
Your GoodReader app password is not stored anywhere outside GoodReader on your device, so there's no way to retrieve it if you've forgotten it. The only way to reset a password is to delete and reinstall the app. Please note that you will also be deleting all files stored inside GoodReader when deleting the app. Try transferring your files to a computer using Apple's iTunes File Sharing before deleting and reinstalling. In the future please try to do two important things: do whatever you can to make sure you don't forget your password, and keep copies of your GoodReader files in a safe place on your desktop computer or server, just in case.

Great PDF editor

This app is critical to my studies. Working in IT, I'm constantly reading through documentation and tech manuals to keep myself up to date with the technologies I work with. This app allows me to thoroughly edit these documents in a way that clearly indicates important information I will need later.


One feature I'd like to see is the ability to take a screen grab of the document I'm reading. I consolidate my notes into a OneNote notebook and often like to include diagrams to illustrate a point I'm reading.
