HTML Formatter & Minifier
Format messy HTML with clean indentation, or minify it to cut its size.
Three steps, no reading required.
Paste your input
Drop text, code, or data into the input pane — from an API response, a file, anywhere.
Pick a mode
Toggle the modes above the output. The result updates instantly as you type.
Copy the result
Grab the output with Copy or Download, or fix the error shown if the input is invalid.
Try it with a sample.
<div class="card"><h1>Hello</h1><p>DevUtilsNow</p></div>
Minify and hope it renders the same
- Uploads your markup
- Beautify and minify live on separate sites
- Risks changing how the page renders
Same page, smaller or tidier
- Minify strips whitespace and comments without changing rendering
- Beautify re-indents nested elements
- Runs in your browser
Questions worth answering upfront.
No. Minifying and beautifying happen entirely in your browser. Your HTML is never uploaded or stored.
Minifying strips unnecessary whitespace and comments to reduce file size and improve load times without changing how the page renders.
Yes. Beautify re-indents HTML with consistent structure so nested elements are easy to read.
Yes. Every tool on DevUtilsNow is free with no account required.
No. Both modes collapse runs of whitespace, so the spacing inside pre and textarea elements is not preserved. Format those blocks by hand, or leave them out of what you paste.
