Frequently Asked Questions About Code Minification
How much file size reduction can I expect?
Typically, you can expect 15-30% size reduction for HTML, 20-40% for CSS, and 10-25% for JavaScript. The exact savings depend on your code's formatting and comment density.
Does minification affect my code's functionality?
No, minification only removes whitespace, comments, and unnecessary characters. It preserves all functionality while making files smaller and faster to load.
Should I minify files for development or only production?
Use minified files only for production. Keep original, readable code for development and debugging. Many build tools can automate this process.
Can I reverse the minification process?
While you can beautify minified code to make it readable again, you cannot recover the original comments and exact formatting. Always keep backup copies of your original files.
Is it safe to minify all types of JavaScript?
Most JavaScript can be safely minified, but some edge cases with dynamic code or specific formatting dependencies might need careful testing after minification.
