❓ Frequently Asked Questions

Why is the current batch limit four PDFs?

The current backend runs on a small free server, so a conservative limit keeps heavy PDF jobs stable.

Can each protected PDF have a different source password?

Not in this batch version. The optional source password is shared across selected files.
