About Text Diff Viewer
The Text Diff Viewer compares two blocks of text and shows what changed. Paste the original into one side and the revised version into the other, and the tool highlights added and removed lines so the differences are easy to spot.
The comparison is computed in your browser, so neither version of your text is uploaded. This is handy for reviewing edits to a document, spotting changes between two config files, or checking what differs between two versions of a snippet before committing it.
Frequently asked questions
- Does it compare line by line or word by word?
- It works at the line level, marking each line as added, removed, or unchanged between the two inputs.
- Can I compare code as well as prose?
- Yes. Any plain text works, including source code, config files, and logs.
- Is my text sent to a server?
- No. Both inputs are compared locally in your browser and are not transmitted anywhere.
