Web ToolBox
Use Web ToolBox for browser-based formatting, conversion, encoding, generation, and validation tasks in web projects.
About Web ToolBox
Web ToolBox is a collection of browser-based tools for everyday web development tasks. The homepage lists 83 tools in the categories of encoding, conversion, generation, and validation. Examples include a JWT Decoder, a Color Code Converter, an XML Formatter, a Text Diff Checker, a QR Code Reader, and an OGP Checker. The site states that no sign-up is required and that the tools are free to use. It can be used on desktop or mobile.
The homepage says that many tools run directly in the browser, so input can stay on the user's device. It does not say which tools work this way. Some tools, such as the OGP Checker and Subdomain Lookup, are described as fetching data from URLs or domains, so their behavior differs from purely local processing. Pricing is not stated on the homepage.
