MyToolStudio

Most free tool sites make you scroll past ads, wait in an upload queue, then ask you to sign up right when you actually need the thing. My Tool Studio doesn't do any of that.

It's a free, browser-based toolkit with 230 tools across 14 categories. JSON, regex, hashing and JWT for developers. Meta tags, sitemaps, schema markup and llms.txt for SEO work. Color pickers, contrast checkers and CSS generators for designers. There's also image editing, PDF tools, text utilities, and bulk operations for when you're churning through a pile of files at once.

Most of it runs entirely in your browser, so your files never reach a server. The few tools that do need server processing delete everything within six hours. No account. No daily limits. No Pro tier. And no ads cluttering the tools while you use them.
