Compare two pasted texts or two TXT, MD or DOCX files in the browser and download a difference report.

Files are not sent to a server. Processing runs in your browser, and the queue handles one file at a time so the device stays responsive.

No files selected.
Uploading a file is optional. Paste the first text in the left field and the second text in the right field below, then click “Process”.

Main mode: paste text into two fields and compare. TXT, MD and DOCX can also be uploaded: the first file fills the left field, the second fills the right field. Old DOC is not supported because it is a binary format.

How to use it

Paste text into the left and right fields, or add two text files. The tool highlights removed, added and unchanged lines locally.

Recommended settings

Ignore edge spaces when comparing copied text from websites. Turn on case sensitivity when capitalization changes matter, such as code or product names.

Privacy

Your files are not uploaded to a server. The editor runs in your browser with local libraries from this site.

Limits

Large images can take longer on phones. If the browser slows down, process fewer files at once or choose a smaller output format.
