Processing stays in your browser worker. Input is limited to 1 MB and output to 3 MB. No input content is saved by CraftAI.
Make HTML source easier to read
Format valid HTML with consistent indentation so nested elements are easier to inspect.
Does formatting HTML make unsafe markup safe?
No. Beautifying code changes presentation, not the security of scripts or embedded content.
