What it is and what it does

htmlmin2 is a Python library that reduces HTML file size by removing unnecessary whitespace, line breaks, and comments while keeping the markup functional. It's designed for developers who need to optimize HTML output in web applications, static site generators, or build pipelines.

The package has no external runtime dependencies, making it lightweight to install. It supports configurable minification with safety features intended to prevent accidental breakage. However, the project is no longer actively maintained—the last commit was 2021-10-20, and the latest release dates to 2023-03-14. This means you should verify compatibility with your target Python version before relying on it in production.

Use it for:

Reduce HTML payload size in web applications before serving to browsers
Optimize static HTML files generated by site builders or templating systems
Strip comments and whitespace from HTML during a build or deployment pipeline
Minify HTML email templates to reduce transmission size
Post-process HTML output to reduce bandwidth usage

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Minifies HTML by removing unnecessary whitespace and comments while preserving functionality, with configurable safety features.

Yes, if you need a simple, dependency-free HTML minifier for a stable project. The low install friction and permissive BSD license make it easy to adopt. However, be cautious: the package is abandoned and may not work with Python versions released after 2021. Test thoroughly with your target Python version before relying on it in production.

Installing htmlmin2

Before you install

Installation is straightforward with no runtime dependencies. However, the package is abandoned—last commit was 2021-10-20 and no updates have been released since 2023-03-14, creating a maintenance risk for future Python compatibility.

License in practice

BSD license is permissive, allowing use in both open-source and commercial projects with minimal restrictions. You must include a copy of the license and acknowledge the original author.

Quickstart

pip install htmlmin2

import htmlmin2
minified = htmlmin2.minify('<html>  <body>  Hello  </body>  </html>')

Verify before relying

Whether the package works reliably with modern Python versions beyond 3.2
What specific safety features are configurable and how they prevent breaking changes
Whether a maintained fork or alternative is recommended given the abandoned status
