FAQ
Does it work with scanned PDFs?
Works best with text-based PDFs. Scanned (image-only) PDFs have limited functionality.
Can I process protected PDFs?
You need to enter the password first. We cannot bypass PDF security.
What is the maximum PDF size?
Depends on device memory since processing is local. Most devices handle up to 100MB.
Is my PDF uploaded anywhere?
No. All processing happens locally in your browser. Your file never leaves your device.
