Frequently Asked Questions

How do I compare two PDFs for free?

Upload the original and the changed PDF, then click "Compare". The text differences are highlighted — green for additions and red for deletions. It is completely free.

What kind of differences does it detect?

It compares the extracted text of both documents word by word and highlights what was added or removed between them.

Does it compare images or layout?

This tool focuses on text content. Visual layout, images, and formatting differences are not part of the text comparison.

Will it work on scanned PDFs?

Scanned PDFs are images with no selectable text, so there is nothing to compare. Use a text-based PDF for accurate results.

Are my PDFs uploaded to a server?

No. MyPDFEasy compares PDFs directly in your browser using Mozilla PDF.js. Your files never leave your device — guaranteed privacy.

How many pages can I compare?

All pages of both documents are read and combined for the comparison. Very large files take longer because everything runs on your device.
