Web Toolbox
Large collection of browser-based developer tools.
FreeCollectionFree to useWeb
Web Toolbox aggregates a very large set of small web utilities — encoders, hash generators, image tools, validators and inspectors — each on its own page with a direct link. It is a fast way to find a specific one-off utility without installing anything, and every tool runs client-side.
