Minify HTML by removing redundant whitespace and comments while preserving preformatted blocks, scripts, and styles. Displays exact UTF-8 byte savings and compression percentage.
Follow these simple steps to get instant, accurate results directly in your browser:
Paste your raw HTML document or code snippet into the input field or click 'Load Sample HTML'.
Inspect the before/after UTF-8 byte counts, total bytes saved, and compression percentage in the savings bar.
Copy the minified markup to your clipboard with one click or download it directly as an index.min.html file.
The HTML Minifier reduces document payload size by collapsing redundant whitespace outside tags and stripping non-conditional HTML comments without altering DOM semantics.
Whitespace-sensitive elements (<pre>, <textarea>, <script>, and <style>) are strictly protected so formatted code, user inputs, and scripts remain intact. Embedded CSS within <style> tags is automatically optimized, while conditional comments for legacy engines and CDATA blocks are preserved.
This minification runs entirely locally in your browser with zero network requests, reporting precise UTF-8 byte counts and overall compression percentage.
Collapses redundant spaces and strips standard comments while preserving conditional tags.
Safely isolates <pre>, <textarea>, <script>, and <style> tags from whitespace modification.
Calculates real UTF-8 byte sizes using browser TextEncoder rather than simple string length.
Processes markup directly in browser memory without sending data to external servers.
Shrink HTML templates and landing pages before publishing to content delivery networks.
Reduce email HTML payload size to avoid message clipping by email service providers.
Evaluate markup compression potential without setting up build toolchains or installing dependencies.
