About this tool

What is a Text Diff Tool?

A text diff tool compares two versions of a document and highlights exactly what changed — word by word, line by line. It is the same technology used by software developers in Git, but made accessible to everyone without any technical knowledge.

GetPDFMint's text diff tool runs entirely in your browser. No text is ever uploaded to a server, which makes it safe to use with confidential documents, legal contracts, medical records, or any sensitive content.

FAQ

Frequently Asked Questions

Is my text sent to any server? +

No. All comparison happens entirely in your browser using JavaScript. Your text never leaves your device and is never sent to GetPDFMint's servers or any third party. It is safe to use with confidential documents.

What is the difference between unified and split view? +

Unified view shows both original and modified lines in one column, like a Git diff. Split view shows original and modified side by side in two columns for easier visual comparison.

Is this tool completely free? +

Yes, completely free. No signup, no account, no character limit, no watermark. Use it as many times as you need.

Can I compare large documents? +

Yes. The tool runs in your browser and handles large documents well. For most articles, contracts, and reports it runs instantly. Very large texts (100,000+ words) depend on your device performance.

How is word-level diff different from line-level diff? +

A line-level diff marks an entire line as changed even if only one word was different. A word-level diff highlights the exact words that changed within each line — so you see precisely what was added, removed, or modified.
