WebUtils is a large collection of browser-based tools covering common developer and everyday tasks. Shortcuts give quick access to JSON formatting and validation, Unix timestamp conversion, Base64 encoding and decoding, and QR code generation. Most tools process data locally in the browser; network-based tools connect to services the user chooses. It is aimed at people who need quick, single-purpose tools without installing separate programs, such as developers, students and general users. Open the tool you need from the collection and work directly in the browser window.
A browser-based collection of over 1,000 everyday utilities, from JSON formatting to QR code generation.
