How compare-anything works
Text diff
Paste or upload two text versions, then compare them side by side or as a unified patch. Character-level highlights show exactly what changed inside edited lines.
Options
Use syntax selection for context, ignore whitespace or case when formatting is not important, and hide line numbers for cleaner exports.
Share and export
Share copies a local link with the current text payload. Export downloads the rendered diff as a plain text report.
Images
Upload two images and move the slider to inspect visual differences with an overlay comparison.
Documents
Document mode checks file metadata and pairs with the main redline area for text extracted from PDFs, DOCX files, or contracts.
Sheets and folders
CSV/TSV mode compares cells. Folder mode compares filenames, file sizes, and modification dates to find new, missing, and changed files.
Guides and policies
Keep the tool first, keep the rest one click away.
Compare text revisions
Review side-by-side and unified diff patterns for drafts, code, and editing passes.
Compare contracts
See a practical workflow for redlines, clause changes, and document checks.
Compare CSV exports
Use structured cell comparison for tables, price lists, and recurring data exports.
Compare folders
Check missing, new, and changed files by path, size, and modification date.

Use cases
What this tool is actually good at.
Review edited copy and marketing text
When the wording matters, side-by-side diff and character-level highlights make it easier to catch changed claims, missing words, altered numbers, and subtle meaning shifts before publishing.
Check contracts and approval drafts
Legal and commercial reviews often depend on tiny edits. Keeping nearby clause context visible helps teams validate dates, obligations, payment values, and notice language with less guesswork.
Compare CSV exports and price lists
Exports from admin systems and shops change often. Cell comparison helps spot missing rows, shifted values, and formatting noise without manually scanning the whole sheet.
Validate handoffs between folders and files
Folder comparison is useful for release packages, client deliveries, and archive checks where missing or newly added files matter as much as changed content.
How it works
A short workflow people can trust.
1. Start with the right comparison mode
Use side-by-side when context matters and unified when you want one compact stream of edits. For code and structured text, syntax context helps reviewers keep their bearings.
2. Check whether the change matters
The tool is not only about finding any difference. It is about deciding whether the changed wording, value, cell, or file actually affects approval, release, pricing, or communication.
FAQ
Questions people ask before they compare.
Does the compared text get uploaded to a server?
The main compare workflow is designed to run in the browser. Compared text and selected content are handled locally in the page and are not stored by this site.
When should I use unified view?
Unified is useful when you want a compact review stream, especially for developer-style change review or when you need to export a shorter diff summary.
Can this help with spreadsheets and exports?
Yes. The sheet comparison area is meant for CSV and TSV input where changed cells, moved values, and altered tables are easier to inspect than in raw exports.
Who is compare-anything for?
It is useful for editors, operations teams, analysts, developers, legal reviewers, and anyone who needs to compare two versions quickly without setting up a heavier workflow.
