Remove comments and unnecessary inter-tag whitespace with conservative browser-side processing.
How to use it
- Keep the readable source and confirm it already passes validation and tests.
- Paste or select the source and run the local minifier.
- Compare the output size and retain source maps or build information where appropriate.
- Run functional, visual, accessibility and compatibility tests before deployment.
How to interpret the result
A smaller result can reduce transfer size, but the saving and runtime behaviour should be measured in the actual production build.
Privacy and limitations
Minification does not remove unused code, fix invalid syntax or guarantee identical behaviour for every dynamic template and browser.
Recommended next step
Deploy through a reversible build process, keep the original source and monitor the affected pages after release.
