django-compressor
Compresses linked and inline JavaScript or CSS into single cached files.
Decision gist · record as of 2026-08-14
Yes. Django Compressor is production-stable, actively maintained, has no known vulnerabilities, and solves a common Django performance need with low install friction. Choose it if you need automatic CSS/JS compression in templates with optional compiler support and offline processing. The MIT license carries no restrictions.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Django 4.2 or later and Python 3.10 or later; rcssmin and rjsmin are runtime dependencies for default minification.
- Low friction install with four runtime dependencies (django, django-appconf, rcssmin, rjsmin).
- Active maintenance with recent commits and production-stable status across Django 4.2 through 6.0.

What it is and what it does
Django Compressor is a Django app that processes CSS and JavaScript in your templates, combining multiple files into single cached assets and minifying them for production. It wraps your stylesheets and scripts in template tags, parses them for linked and inline resources, applies optional compilers (like LESS or SASS), and outputs optimized `<link>` or `<script>` tags pointing to versioned files. Because the filename is content-dependent, these files can be cached indefinitely without stale-cache concerns.
The package is highly configurable: you can choose between lxml, BeautifulSoup, html5lib, or a custom HTML parser; swap in different minifiers (YUI Compressor, Closure Compiler, JSMin, csscompressor); or write custom filters for post-processing. For offline workflows, a management command lets you pre-compress assets outside the request cycle. It depends on django, django-appconf, rcssmin, and rjsmin, and supports modern Django versions (4.2 through 6.0) and Python 3.10+.
Use it for
- Reduce HTTP requests and bandwidth by combining multiple CSS files into one cached asset in production
- Automatically minify inline JavaScript and CSS in Django templates without manual build steps
- Compile LESS or SASS stylesheets and minify them in a single pipeline step during template rendering
- Serve versioned static files with far-future cache headers, ensuring browsers never serve stale assets
- Implement custom asset processing (e.g., image-to-data-URI conversion) via extensible filter classes
