Operation
Tried only on source PDFs that are encrypted. A locked file without a matching password is skipped — the rest still process.
Note: if a source PDF was password-protected, its output is saved without the password. Re-lock it with Protect if you need to.

Frequently asked questions
Common questions about the Batch PDF Tools.
How many PDFs can I process at once?
There is no fixed limit — because everything runs in your browser, you are bounded only by your device's memory. Files are processed one at a time to stay memory-friendly, with a live progress list.
What if one file fails or is password-protected?
The batch keeps going. Any file that can't be processed is marked as skipped with a short reason, and every successful file still lands in your ZIP. You can supply one password to try across locked files.
Do my files get uploaded anywhere?
No. Batch processing happens entirely on your device — none of your PDFs are uploaded, stored or seen by any server, which is exactly why there is no file-count limit or fee.
Which actions can I batch?
Compress (with quality presets), add page numbers, protect with a password, and unlock (remove a known password). More batch actions can be added over time.
