About this tool
See what changed between two versions of a contract or document. The result is one PDF: the original on the left (removed words in red) and the new file on the right (added words in green). Only PDFs that contain text can be compared.
When to use it
Find what changed between two versions of a document, such as a contract, report or CV. Differences are shown as a coloured overlay, side by side, and page by page.
Tips
Use the same page size for both files. Changes in layout can show as differences even if the words are the same, so check the changed pages list.
Privacy
Everything runs in your browser, so your data is not uploaded or stored.

常見問題
Can scanned PDFs be compared?
No. Run "OCR PDF" first to get the text, then compare.
How do I tell original from new?
The first file in the list is the original and the second is the new one. Use the arrows to swap.
Does it compare text or looks?
It compares how the pages look, so every visual change is found.
How many pages can I compare?
Typical documents work well. Very long files can be slow on phones.
