About MicroKit File Diff

MicroKit File Diff is a high-performance, privacy-first file and text comparison tool powered by Rust and WebAssembly (WASM). Compare source code, plain text, PDF documents, and Word (.docx) files side-by-side or inline directly in your browser.

Key Features

  • Multi-Format Support: Compare plain text, source code files, PDF documents, and DOCX files.
  • Syntax Highlighting & Export: Automatic syntax highlighting for multiple programming languages with options to export comparison results as HTML or PDF.
  • Side-by-Side & Inline Modes: Switch between side-by-side and unified inline diff views with a single click.

Q: What file formats are supported?
A: You can compare raw text, PDF files (.pdf), Word documents (.docx), and code files across popular languages (JavaScript, Rust, Python, C/C++, HTML, CSS, JSON, and more).
