Line-by-line comparison
No differences found.
Added 0
Removed 0
Unchanged 0
Text is compared in this browser, one line at a time. Blank lines and trailing line breaks are included.
Read the comparison
Added lines appear with a plus sign and a green background; removed lines use a minus sign and a red background. Unchanged lines remain in the output so you can follow the surrounding context.
The comparison is line-based. A changed line is shown as a removal and an addition, and blank lines or trailing line breaks are treated as part of the text.
Common questions
Is my text uploaded?
No. The comparison runs in your browser, and the text is not sent to a server.
Can I compare files?
This tool compares text pasted into the two fields. Copy text from a document or code editor to compare it here.
Want the steps behind the result?
Learn a simple way to compare two text versions, review additions and removals, and avoid treating a difference report as approval of the newer draft.
