02 / TROUBLESHOOTING

Troubleshooting

  1. If a PDF cannot be imported, confirm that it has a .pdf extension, that the file is not damaged, and then select it again from the system Files picker.
  2. If photo, scan, text, Markdown, or Office conversion fails, confirm that the format is supported and that the device has enough storage, then retry with fewer files.
  3. If reordering, deleting, splitting, merging, ZIP creation, or saving fails, close other memory-intensive apps, reopen PDF Editor, and try again. Splitting does not replace the original PDF.
  4. If Computer Transfer cannot connect, keep both devices on the same Wi-Fi, leave the app in the foreground, allow Local Network access, and re-enter the displayed address and six-digit pairing code in the computer browser.
  5. If you cannot find a file after sharing it, check the destination app or the location you selected in the system Files app.

03 / FAQ

Frequently Asked Questions

Are my PDFs or other documents uploaded to the developer's server?

No. PDF editing, Office/text/Markdown/photo conversion, and ZIP creation happen on the device. Only when you start Computer Transfer are selected files sent directly between your device and computer on the same local network; they do not pass through a developer-operated cloud server.

How do I delete PDFs stored in the app?

Enter selection mode in the PDF library, select the documents you no longer need, and delete them. Before deletion, use the system share feature to save any copies you want to keep.

Can documents be restored after the app is uninstalled?

Documents stored in the app sandbox are normally deleted when the app is uninstalled. Before uninstalling, share or save important PDFs to Files or another location.
