Tips

Code is uploaded

MinifyCode runs on Toolomix. Your source is sent to the server—not minified only in the browser.

Simple minifier

Expect comment/whitespace-style compaction. This is not Terser, esbuild, or a full production bundler.

Pick the correct type

Choose HTML, CSS, or JavaScript so the server applies the matching minify rules.

Test before shipping

Always verify minified output in your real app before deploying.

MinifyCode on the server

POSTs code and type to /web-tools/MinifyCode and returns compacted text plus size stats.

HTML, CSS, and JavaScript

One tool for the three common front-end source types.

Size comparison

See original size, minified size, and compression percentage from the server response.

What this tool does

Code Minifier compresses pasted HTML, CSS, or JavaScript on Toolomix and shows how much size was reduced.

It uses a simple server minifier—not Terser, esbuild, or a full build pipeline.

How to use

Choose the code type

Select HTML, CSS, or JavaScript.

Paste your source

Add the code you want to minify into the input field.

Minify on Toolomix

Submit so MinifyCode can process the upload and return compacted output.

Copy the result

Review size stats, then copy the minified code.

Supported inputs and output

Input: pasted code text plus a type (html, css, or javascript).

Output: minified code string with original size, minified size, and compression ratio. No separate comment/whitespace toggles in the UI.

Processing and privacy

Your source code is uploaded to Toolomix via POST /web-tools/MinifyCode. Processing is not browser-only.

See the Privacy Policy for how requests and logs are handled.

Limitations

Known limits

  • Simple server minifier—not Terser/esbuild/bundler
  • No remove-comments / remove-whitespace UI toggles
  • Code is sent to Toolomix
  • Requires a successful MinifyCode response
  • May not handle every edge-case syntax safely—test output

Troubleshooting

If minification fails, confirm the input is not empty, the type matches the pasted language, and retry.

If the result looks wrong in your app, keep the original source and try a dedicated production minifier in your build toolchain.

Frequently Asked Questions

Is minification browser-only?

No. Your code is POSTed to /web-tools/MinifyCode on Toolomix and the minified result is returned.

Which types are supported?

HTML, CSS, and JavaScript (type values used by the API include html, css, javascript/js).

Can I toggle remove comments or whitespace?

No. This UI does not offer those separate options. The server applies its default minify behavior for the selected type.

Is this the same as Terser or esbuild?

No. It is a simple server-side minifier, not a full bundler or advanced JS optimizer pipeline.

Will minifying break my code?

It aims to preserve behavior while compacting, but always test. Unusual or syntax-sensitive code can still break.

Can I un-minify back to the original?

Not with this tool. Keep your readable source. Formatting tools may improve readability but cannot restore removed comments.

Why did minification fail?

Empty code is rejected. Otherwise check the type selection, retry MinifyCode, and read the on-page error.
