Frequently Asked Questions
What does HTML minification do?
HTML minification removes whitespace between tags, HTML comments, optional closing tags, and redundant attributes. This reduces file size by 20-50%, making pages load faster without changing how they look.
Will minification break my HTML?
No. Minification only removes characters that browsers ignore. The visual output is identical. However, inline JavaScript or CSS within the HTML may need careful handling — this tool preserves script and style tag contents.
Is my code sent to a server?
No. Everything runs 100% in your browser using JavaScript. Your HTML never leaves your device.
Should I minify HTML for production?
Yes. Minified HTML loads faster and uses less bandwidth. Most build tools (webpack, Vite, Next.js) do this automatically. This tool is useful for one-off files, email templates, or static pages not processed by a build tool.
How much smaller will my HTML be?
Typically 20-50% smaller depending on formatting. Well-indented HTML with many comments sees the biggest reduction. Already-compact HTML may only shrink 5-15%.
