Compare two texts with advanced diff algorithms and visualization options
Paste your texts directly into the text areas or upload files. Supports various file formats including code files.
Configure options like ignoring whitespace, case sensitivity, and comparison algorithm to match your needs.
See differences highlighted in multiple view modes, analyze statistics, and export results in various formats.
Switch between side-by-side and unified diff views. Show only changes or include context lines.
Choose from line-by-line, word-by-word, character-by-character, or sentence-based comparison algorithms.
Export results as HTML reports, unified diff patches, or JSON data for further processing.
Get comprehensive statistics including similarity percentage, lines/words changed, and change summaries.
Ignore whitespace, case differences, or configure context lines. Customize the comparison to your needs.
Upload text files, code files, or any text-based documents. Supports all major programming languages and formats.
The tool accepts any text-based file including .txt, .md, .js, .ts, .html, .css, .py, .java, .cpp, .c, .php, .rb, .go, .rs, .kt, .swift and more. Binary files are not supported.
Line-by-line is best for code and structured text. Word-by-word works well for prose and documents. Character-by-character shows the finest detail but can be overwhelming. Sentence-by-sentence is ideal for comparing articles and essays.
Yes! You can export results in multiple formats: HTML for sharing and viewing, unified diff patch format for version control systems, and JSON for programmatic processing.
Files are limited to 10MB for optimal performance. For very large files, consider breaking them into smaller sections or using desktop tools designed for large file comparison.
The similarity percentage is calculated based on the number of unchanged characters versus total characters. It provides a good general indication, but the meaning depends on your specific use case and the type of changes made.
