How this tool works

BEFORE YOU USE THE RESULT

Assumptions & limitations

This is a set-based line comparison, not a character-level or ordered source-control diff.

The tool does not connect to your website, change your hosting or install anything in WordPress. Any output must be applied separately in the intended environment.

Common questions

Do I need an account?

No. This tool works in a modern browser with JavaScript enabled. Your inputs are not submitted to a server by the tool.

Can I save the result?

Use Copy for the textual result or Download for a local file. Image tools download a generated image when one is available.

Will it change my live website?

No. It produces a result for you to review. Production changes remain a separate step.
