100% private processing

All operations happen on your device using WebAssembly. Nothing is uploaded — perfect for sensitive documents.

Filter

Color Picker

Pick and convert color formats

CSS Gradient Generator

Generate CSS gradient code visually

HTML Minifier

Minify HTML for faster loading

JSON Formatter

Format and validate JSON data

Regex Tester

Test regular expressions live

WikiPlus code tools are built for developers who want quick, offline-safe utilities without opening an IDE. Format messy JSON into readable indentation, test a regular expression against live input and see the match groups highlighted, pick brand-matched colour palettes, craft a CSS gradient with a visual editor that outputs the exact property string, or minify an HTML snippet before production. Everything runs locally in your browser, so your source code is never sent to a third-party service.

Every tool on this page runs entirely inside your browser. Nothing is uploaded to our servers, nothing is cached for later, and no account is required. Files are processed on your own device using WebAssembly modules and the open-source libraries that power each utility, which means confidential documents stay confidential — even if you disconnect from the internet after the page loads, most tools will still finish their job. Pick the utility you need below and start working straight away.

Frequently asked questions

Does formatting JSON change the underlying data?

No. The formatter only rewrites whitespace — keys, values, and ordering stay identical. Re-parsing the formatted output yields the same JavaScript object, so downstream APIs and scripts cannot tell the difference.

Which regex flavour does the tester use?

The tester uses the JavaScript RegExp engine (ECMAScript), matching what a browser or Node.js would execute. If you are targeting Python, PCRE, or Go, features like lookbehind may differ — test in your actual runtime before relying on it.

Can I paste large code snippets into the tools?

Yes — the formatter and minifier handle multi-megabyte files without trouble. For 10 MB and larger inputs, keep the browser tab focused during processing because browsers throttle CPU for background tabs.
