If the app freezes while loading a file
Try opening this file in the Preview app - this is a standard macOS viewer that uses the same system component as our app.
- If the file looks good in the Preview app but freezes in PDF Expert, please contact us at rdsupport@readdle.com and, if possible, share the affected file with us - we're happy to help you personally. If you can't attach the file to the email, please upload it to either WeTransfer or a similar file-sharing service (for instance, Google Drive) convenient to you and send us the link.
- If the file looks the same in the Preview app, the problem is file-specific. It's likely that Apple is aware of such cases and a new macOS update might fix the problem - still, if you'd like to make sure your vote is added for the fix they have registered, you may contact Apple Support.
- Check if the file contains vector graphics. These are either diagrams and graphs or the text that doesn't look blurry or pixelated even if you zoom it in drastically. Such a file can also look like a checkered background - in this case, it means that the graphics are heavy and our app needs some time to load the content.
- Try opening this PDF in the iBooks app - this is a standard iOS app that uses the same system component as we do:
- If the file looks the same in the iBooks app, the problem is file-specific. We're sure that Apple is aware of such cases and a new iOS update might fix the problem - still, you may want to contact Apple Support to make sure your vote is added for the fix they have registered.
- If the file looks good in the iBooks app but freezes in PDF Expert, please contact us at rdsupport@readdle.com and, if possible, share the affected file with us - we're happy to help you personally. If the file's size is too big for sending it over email, you can upload it to any cloud storage service and share a link with us - e.g., you can use the WeTransfer service.
