HTML minifier & beautifier

Paste HTML and either minify it — stripping comments and collapsing the whitespace between tags — or beautify it with clean indentation. A real tokenizer keeps the content of pre, textarea, script and style exactly as it was. Nothing is uploaded.

How it works

STEP 1

Paste your HTML

Drop in a page or a fragment of any size. Tags, comments, the doctype and raw blocks like script and style are all handled.

STEP 2

Minify or beautify

Minify to strip comments and collapse whitespace for the smallest output, or beautify to re-indent every tag cleanly. Pick your indent and options.

STEP 3

Copy or download

See the byte size saved, then copy the result with one click or download it as an .html file. Nothing leaves your device.
