About html formatter / minifier

Format or minify HTML. It sits in the developer shelf alongside 76 other developer tools, needs no account, and keeps the same behaviour whether you open it here or call it through the REST API.

It works from what you type in rather than a file and gives back HTML. The work happens in your browser, so nothing is sent to us at all and the tool keeps working offline. The same operation is available programmatically at POST /v1/dev/html-formatter.

HTML Formatter / Minifier questions

Does HTML Formatter / Minifier upload my file?

No. HTML Formatter / Minifier runs as WebAssembly inside this browser tab: the file is read from your disk by the page, processed on your own machine, and handed straight back. It is never sent anywhere, so there is nothing for us to store or delete.

Do I need an account to use HTML Formatter / Minifier?

No. HTML Formatter / Minifier works without signing in, and that is not a trial — it is how the free tier works. An account only matters for things that need one to exist at all: larger server jobs against your quota, API keys, saved workflows and billing.

Can I run HTML Formatter / Minifier from my own code?

Yes. Every tool on the site is reachable from the REST API with the same slug — `html-formatter` — and the same options as this page, so anything you can do here you can automate against your own files.
