About Text Diff

Text Diff is an essential utility for developers, writers, and editors to instantly visualize the differences between two versions of text.

Comparison Modes

  • Characters: The most granular mode. Perfect for finding small typos or single-letter changes in passwords or API keys.
  • Words: Best for comparing articles, essays, or natural language text. It highlights entire words that were changed.
  • Lines: The standard for comparing source code, configuration files, or CSV data.

Privacy First

Unlike many online diff tools that send your data to a backend server for processing, this tool performs the heavy lifting directly on your device using WebAssembly and optimized JavaScript. Your sensitive code and documents are completely safe.
