Compare two texts and highlight the differences line by line. Free, no signup required. Use it right in your browser.
What it does, limits, use cases, tips, and answers to common questions.
A diff shows what changed between two texts: a contract revision, two JSON configs, or a paragraph you edited. This checker highlights insertions and deletions in the browser.
It is a text diff, not a Word track changes import and not a binary diff for images. Whitespace only changes still show unless you normalize first.
Local comparison is the point when the two versions are confidential. Paste both sides; nothing is stored on a server.
Huge files (multi megabyte dumps) can be slow in the tab.
Moved blocks may look like delete+insert rather than a move.
This does not merge conflicts; it only displays them.
Reviewing a policy rewrite.
Checking two API responses.
Confirming a CSV export actually changed.
Normalize line endings (CRLF vs LF) if the whole file looks changed.
Paste plain text, or convert to text first. .docx binaries will look like garbage.
