📋 How to use Compare PDF – step by step

  1. Choose the old PDF and the new PDF
  2. Choose page by page or whole document
  3. Click "Compare the PDFs"
  4. Open the pages marked changed to see green (added) and red (removed) words
  5. Copy the short summary if you need it

💡 Why use this tool?

Agreements, notices, circulars and reports often come in many versions. Finding what changed by reading both is slow and risky.

This tool lists every added and removed word, so you can check a new version in minutes.

❓ Frequently asked questions

Does it compare pictures and layout?

No. It compares only the text of the PDFs. A change in a picture, table shape or colour is not shown.

Why does it say there is no selectable text?

The PDF may be a scan, where the text is a picture. Run OCR on it first, then compare.

Does it work with Telugu PDFs?

Yes, if the Telugu text in the PDF is real text. Some old Telugu PDFs use special fonts that give broken text when copied. Then the comparison may show many differences. Use the Non-Unicode to Unicode tool first.

What if the new PDF has inserted pages?

Use "whole document" mode. Page by page mode compares page 1 with page 1, page 2 with page 2 and so on, so an inserted page makes later pages look different.

Is my PDF uploaded?

No. Everything happens in your browser.

Is it free?

Yes, completely free.
