About Text Diff Highlight
Text Diff Highlight is a high-performance web utility built to compare two text documents side-by-side. Highlight character additions, deletions, modifications, and line changes visually instantly and securely. Because it is designed with a local-first architecture, all processing occurs directly in your browser's memory using client-side JavaScript. This ensures that your files, code, or private text inputs are never uploaded to any external server or tracked by third-party analytics.
Whether you are formatting source code, cleaning text files, converting file structures, or running diagnostics, running these processes locally in your browser memory sandbox eliminates network latency and protects your data privacy.
