About Text Compare

Text Compare is a free online utility for checking differences between two pieces of text, code, or document content.

What the tool does

Text Compare helps developers, writers, editors, students, and support teams compare two versions of text side by side. It highlights added, removed, and changed content so revisions are easier to review.

Privacy-first design

The comparison tool runs in your browser. Text entered into the compare boxes is processed locally by JavaScript and is not uploaded to our server for comparison.

Useful comparison modes

The tool supports side-by-side comparison, inline comparison, line-by-line review, and word-level diff. It also supports common plain-text file formats such as TXT, Markdown, JSON, CSV, XML, HTML, CSS, JavaScript, and log files.

Our goal

Our goal is to keep text comparison fast, accessible, and simple while adding practical features that help people review real work more accurately.
