Frequently Asked Questions

What does HTML minification do?
HTML minification removes all characters a browser doesn't need to render the page — whitespace, newlines, comments, and redundant spaces between tags. The output is functionally identical to the input but smaller and faster for the browser to parse.
How much can minification reduce HTML file size?
Typically 10–30% depending on whitespace and comment density. A template-heavy HTML file with lots of indentation can shrink 20–30%. A lean HTML file may only see 5–10% savings. HTML files also benefit heavily from gzip/Brotli compression.
Is my HTML code sent to your servers?
No. All processing happens entirely in your browser using JavaScript. Your HTML code never leaves your device and is never transmitted to any server. Any sensitive comments or internal developer notes in your code remain completely private.
What exactly gets removed during HTML minification?
Removed: all HTML comments (<!-- ... -->), extra whitespace and newlines, and spaces between closing and opening tags. Preserved: all HTML tags, attribute names and values, text content, inline scripts, and inline styles.
Is it safe to minify HTML for production?
Yes. This minifier performs safe whitespace and comment removal only. It does not alter tag structure, attribute values, or any content. The output is production-ready and can be deployed directly to your web server.
What filename format does the download use?
The file downloads as [your-filename].min.html, preserving the original uploaded filename. For example, uploading index.html gives index.min.html. If you pasted code without uploading a file, it defaults to index.min.html.
Is there a file size limit?
Yes — 2MB maximum. A typical HTML page is 10–200KB, well within the limit. Large HTML email templates or documentation files can be split and minified in sections.
Is this HTML minifier free?
Yes. FindBeam's HTML Minifier is completely free with no account, no registration, and no usage limits. It will remain free.
