About this tool
Word by word
The text of each page is compared with the same page of the other file, so you see precisely which words were added or removed.
What it compares
Text only. Changes to images, colours or layout aren't shown, and scanned pages need OCR before they have text to compare.
Frequently asked questions
What if pages were added or removed?
Pages are compared in order, so an inserted page shifts the comparison for the pages after it; extra pages are shown as added or removed.
Is there a size limit?
Very different documents are compared line by line instead of word by word, so the browser stays responsive.
Is my file uploaded?
No. It's processed in your browser and never leaves your device.
