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.

獲得最佳結果的提示

開始之前請花一點時間閱讀選項,並先用一個小例子試用工具。一切都在您裝置的瀏覽器中執行;您輸入或新增的任何內容都不會被上傳,關閉標籤頁會清除所有內容。如果看起來不對,請重新整理頁面重試,或使用本頁的報告連結告訴我們出了什麼問題。如果結果仍然看起來不對,請每次只更改一個值,看看哪個輸入影響最大。如果您還會再用,請收藏此頁。

要點

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.
