Common issues and how to fix them.
- Make sure the selected file is a valid PDF — try opening it in a PDF viewer first
- Password-protected PDFs cannot be read; remove the password protection first
- Very old or non-standard PDF formats may not be supported
- The source PDF may be corrupted — try opening it in a PDF viewer and saving a fresh copy
- If the file is very large, ensure you have enough disk space in the output folder
- Try splitting a smaller range first to isolate which pages cause the issue
In Folder of PDFs mode, a file that fails to load or split (for example, a password-protected PDF) doesn't stop the batch — the app skips it and keeps going. Check the finishing summary for the list of failed files, fix or remove them, and rerun with Skip files that already exist checked to avoid re-processing what already succeeded.
Output files are named with zero-padded numbers (001, 002, …) so they sort correctly alphabetically in Windows Explorer. If files appear out of order, check that your file explorer is sorting by Name (not by date or size).
If Skip files that already exist is checked, the app skips chunks that are already present in the output folder. Uncheck this option to overwrite existing files, or delete the existing output files first.
- Check that you have write permission to the output location
- Avoid network drives or synced folders (OneDrive, Dropbox) as the output location — use a local path such as
Documents\BatchSplitPDFsinstead
- Check that Windows is up to date; the app requires Windows 10 or later
- Reinstall the app from the Microsoft Store if the issue persists
