What is HTML Formatter?
HTML Formatter is a free, browser-based tool on TitanFile that lets you beautify and properly indent messy HTML code. Fix minified HTML, clean up CMS output, and make web page source code readable. Everything runs locally on your device — no files are ever uploaded to any server.
How do I use HTML Formatter?
Open the HTML Formatter page, add your file or enter your data, adjust any settings, then click the action button. Your result is ready instantly — no sign-up or installation required.
Are my files private?
Yes — all processing happens entirely in your browser using JavaScript. Your files and data never leave your device and are never uploaded to any server. We cannot see your files even if we wanted to.
Does this work offline?
Once the page has loaded, HTML Formatter works without an internet connection. You can install it as a PWA to your home screen for instant offline access.
Is there a file size limit?
There is no server-side limit because everything runs locally in your browser. The practical limit is your device's available memory. Most modern devices handle files up to several hundred MB without issue.
Why is this free?
TitanFile is ad-supported and passion-driven. We believe powerful tools should be accessible to everyone. HTML Formatter — like every tool on TitanFile — will always be free with no paywalls, watermarks, or hidden fees.

Client-side only

HTML Formatter runs entirely in your browser tab. Your code and text never touch a server.

Works offline

Once the page loads, you can disconnect. Install TitanFile as a PWA for instant offline access anytime.

Free forever

No tiers, no rate limits, no expiring trial. Every tool on TitanFile is and will remain completely free.
