Beautify and format TypeScript

Paste messy or minified TypeScript and get it back cleanly formatted with consistent indentation, spacing, and line breaks. It's powered by Prettier's standalone build, so the result matches the formatting millions of developers already use. Big files are formatted in the background, errors show the line in a syntax-coloured editor, and you can open or drop files.

Everything runs in your browser — there's no upload, no queue, and no account. Paste, format, copy, download, or send it to Code Compare to see the changes.

TypeScript Beautifier — frequently asked questions

How do I beautify TypeScript?
Paste your TypeScript into the left panel and the formatted result appears on the right instantly. Copy it or download it as a file.
What does the TypeScript beautifier do?
It re-indents and reformats your TypeScript with consistent spacing and line breaks, using the same battle-tested engine (Prettier) many teams run in their editors — so the output matches a widely accepted style. Indent, line width, quotes, semicolons and trailing commas are yours to set, and the choices are remembered. TSX is read too.
Is my code uploaded anywhere?
No. Formatting and minifying run entirely in your browser with JavaScript — your code never leaves your device. It's free with no sign-up.
