What is Text Diff/Compare?

The Text Diff/Compare tool highlights the exact differences between two pieces of text. See additions, deletions, and modifications color-coded side by side or in a unified view — perfect for comparing code versions, document revisions, or configuration files.

How to use

Paste the original text in the left panel and the modified text in the right panel.
View the highlighted differences: green for additions, red for deletions, and yellow for modifications.
Toggle between side-by-side and unified diff views, or copy the diff output for documentation.

Result

A developer pastes two versions of a config file and instantly sees that 3 lines were added, 1 was removed, and 2 were modified — with each change highlighted in context.
