Need to beautify html markup with indentation? HTML Formatter runs in your browser with a simple, focused interface.
AllToolHub emphasizes local processing: snippets stay in the editor unless you choose to copy them elsewhere. That is especially useful when documents or drafts should not be sent to an unknown cloud converter.
Use the workspace above to run HTML Formatter, then explore related tools if your workflow continues (for example, compress after merge, or validate after format).
Yes. HTML Formatter on AllToolHub is free, requires no account, and is built to run in your browser without a paid plan or watermarks from us.
Processing is designed to happen locally in your browser whenever possible. snippets stay in the editor unless you choose to copy them elsewhere. Standard web hosting may still log technical page requests, not your file contents.
After the first visit, the Progressive Web App cache can keep many pages available offline. Tool scripts must be cached first; heavy libraries load when you open the tool.
HTML Formatter is built for front-end developers and designers. Beautify HTML markup with indentation.
You get a consistent, fast UI, private local processing when possible, light/dark mode, and no mandatory sign-up — plus related HTML & CSS Tools in one place.
