Text Differences

Compare PDF Files Online

Instantly see the differences between two versions of a document side-by-side.

Never Miss a Revision

When you are negotiating a contract, working on a team project, or reviewing legal terms, keeping track of what changed between "Version 1" and "Version 2" is exhausting. Reading them side by side on two different monitors is a recipe for disaster, as human eyes easily gloss over altered paragraphs or deleted clauses. You need a reliable way to compare PDF files automatically.

Our comparison engine analyzes the text and visual structure of both documents and highlights exactly what was added, removed, or modified. To find differences in PDF files manually takes hours; our tool does it in seconds, giving you peace of mind that no sneaky changes were slipped into the final draft before you sign it.

Since you are likely comparing highly sensitive internal documents, our tool is built to respect your privacy. The entire visual and textual analysis occurs locally in your web browser. Neither version of your file is uploaded to the cloud, meaning your confidential data remains completely safe on your own machine.

How to Find Changes

  1. Upload Files: Drop the original file on the left, and the revised file on the right.
  2. Analyze: Click the compare button. The tool will rapidly scan both documents line by line.
  3. Review Highlights: Added text, deleted text, and formatting changes will be brightly highlighted for you to review.

Frequently Asked Questions

Does it check images or just text?

Our advanced comparison tool looks at the visual layout as well as the text layer. This means if someone swaps a chart or moves a logo, it will flag that area as a difference.

Can I export the comparison report?

The visual highlights are currently displayed directly in your browser window for immediate review. For now, you cannot download a standalone 'report' file, but you can see every change on screen.
