How to compare text online
Paste the earlier version into Original text and the newer version into Changed text. Choose line, word or character comparison, adjust the options if needed, and select Compare Text to see an aligned result.
What does a text comparison tool show?
A text diff checker separates unchanged content from additions, removals and changed content. Empty placeholder rows keep the two sides aligned when a line exists in only one version.
Line-by-line text comparison
Lines mode is useful for code, configuration and documents where the position of each complete line matters. Line numbers make it easier to locate a change in the source editors.
Word and character differences
Words mode highlights edits inside a line while Characters mode helps inspect small punctuation, spelling or formatting changes. Large character comparisons are limited to protect browser responsiveness.
Common uses for a text diff checker
Compare drafts, review code changes, check copied content, inspect configuration updates or confirm that a published revision contains the expected edits.
Privacy and browser-based comparison
The comparison engine runs locally in your browser. Your text is not sent to WCODX, uploaded to a processing endpoint or saved by this page.
