Toolk

Toolk is an open-source collection of free online utilities, converters, and formatters. Its supported tools run in the browser so common formatting and conversion tasks do not require sending the entered content to a Toolk application server.

• Formatters & Beautifiers — Format JSON, XML, CSS, HTML, and SQL instantly.
• Encoders & Decoders — Fast Base64, URL, and HTML entity converters.
• Design Tools — Generate, extract, and convert colors and palettes.
• Crypto & Hashing — Generate MD5, SHA-1, SHA-256 hashes right in your browser.
• Developer Calculators — Units converters, epoch timestamp utilities, and regex testers.

Private by Design

Supported transformations are executed in the browser. As with any browser-based tool, review the current source, privacy information, and your device or extension environment before entering sensitive data.
