FAQ
Is my PDF uploaded anywhere?
No. All processing happens locally in your browser. Your file never leaves your device.
Does it work with scanned PDFs?
Works best with text-based PDFs. Scanned (image-only) PDFs have limited functionality.
What is the maximum PDF size?
Depends on device memory since processing is local. Most devices handle up to 100MB.
Will formatting be preserved?
Original formatting including fonts, images, and layout preserved as much as possible.
