Are my PDFs uploaded?

No — all PDF processing runs in your browser using PDF-lib and PDF.js. Files never leave your device.

Can I edit existing text in a PDF?

You can cover existing text with a Whiteout rectangle and add new text on top using the Text tool. True reflowing of existing PDF text requires server-side rendering which is not available in browser-only tools.

What is the maximum PDF size?

Up to 50MB per PDF file. All processing happens locally in your browser.

How many pages can a PDF have?

There is no page limit for compress, rotate, watermark, and merge operations. PDF to image conversion supports up to 50 pages due to browser memory constraints.
