How do I compare two texts?

Paste the original on the left and the changed version on the right. Removed lines are shown in red and added lines in green.

Is there a size limit?

Each side is limited to 2000 lines to keep the comparison fast.

Are my files uploaded anywhere?

No. Comparison happens entirely in your browser. Nothing is sent to a server, so your data stays on your device.

Text Diff Checker

Original

Changed

Compare two texts line by line

A diff checker highlights what changed between two versions of a text: lines that were removed, and lines that were added. It is handy for comparing drafts, config files, code snippets or copied web text.
