HTML Formatter
Format HTML with readable indentation.
How to use the HTML Formatter
Paste your input
Drop the snippet, token or document into the editor. Invalid characters are highlighted as soon as parsing fails.
Choose how to process it
Select formatting, validation or conversion options. Results are calculated as you type, with no submission step.
Copy or download
Use the copy button for a clean result, or download it when the output is large.
What HTML Formatter is for
Beautify pasted HTML, preserve inline content and optionally minify it for production. Whitespace inside pre and textarea tags is respected.
The HTML Formatter is part of the Developer collection on ToolFlow. It is designed for one concrete job: format HTML with readable indentation. Everything runs client-side, so you can use it with sensitive material without creating a copy on someone else's server.
Common use cases
- Clean an email template
- Tidy a legacy page
- Prepare a snippet for review
Good to know
- No account is required, and there is no usage limit on the browser tool.
- Processing happens locally. Files are read from disk and the result is written back to your downloads folder.
- Results are reproducible: the same input and options produce the same output, with no hidden server round-trip.
- If the tool needs a live data source, the page states it explicitly instead of silently failing.
