Yes, with no watermark and no page limit.

Does it need an account?

No. There is no account system.

Is my file processed on my device?

Yes. The file is read by your browser and never uploaded. There is no server to send it to.

What formats are supported?

HTML in, including minified. Formatted HTML out, or minified back down.

Formats the markup you give it and does not rewrite it. It will not close your unclosed tags or correct invalid nesting.

Does it work on mobile?

Yes, on any modern mobile browser. Large files are limited by the memory the phone gives the browser.

Does it work offline?

Yes, once the page has loaded. The tool keeps working with no network connection.

Will it fix my broken HTML?

No, and that is on purpose. It formats what you give it rather than guessing at what you meant, because a formatter that silently adds closing tags can change how the page renders while looking like it only changed the whitespace.

Does it handle minified HTML from a built site?

Yes. That is the main reason people open one. Paste the whole thing in and it comes back with one element per line and real indentation.

What happens to my inline JavaScript and CSS?

It is passed through untouched. The contents of script and style are treated as text, not markup, so nothing inside them is reindented or misread as a tag.

Why does not get a closing tag?

Because in HTML it never has one. br, img, input, meta and the rest of the void elements are complete on their own. Adding a closing tag would be invalid HTML, so the formatter leaves them as they are.

How it works / no cloud

A conversion engine, not an upload form.

filetity parses the HTML in your browser and prints it back indented. It knows the void elements that never close, and it treats the contents of script and style as text, so a comparison like a < b inside a script is not mistaken for the start of a tag.
