Diff checker: compare text and code
Paste two versions of a document, a config file or a piece of code and see exactly what changed. Additions and removals are highlighted per line and per word, with options to ignore whitespace and case. Nothing you paste leaves your browser.

Questions and answers
How do I compare two files online?
Open or paste each file into its side, and the differences appear immediately.
Can I ignore whitespace differences?
Yes. Turn on the ignore whitespace option to hide changes that are only spacing.
Are my texts stored?
No. Comparison runs locally and nothing is uploaded or saved.
