Common tasks
HTML Minifier & Cleaner — frequently asked questions
What does HTML minification do for page speed?
Minification removes HTML comments, strips excessive indentation and spaces between tags, and collapses multi-line text blocks. Smaller HTML documents download faster and parse quicker, directly improving First Contentful Paint (FCP) and Time to First Byte (TTFB).
Does the formatter handle void elements and doctypes correctly?
Yes. Standard HTML5 doctypes (`<!DOCTYPE html>`) and self-closing or void elements such as `<meta>`, `<link>`, `<img>`, `<input>`, and `<br>` are preserved according to W3C specifications.
Can I beautify tangled or minified HTML?
Yes. Beautify mode organizes nested elements into clean hierarchies with configurable 2-space or 4-space indentations.
Are my web templates or HTML documents transmitted online?
No. All parsing and formatting occur purely in client-side memory on your device with zero server communication.
Does it support SVG and embedded script tags within HTML?
Yes. Embedded SVG vector blocks and inline `<script>` or `<style>` tags are recognized and safely processed.
