About ToolMixr
Free online tools that respect your privacy.
What is ToolMixr?
ToolMixr is a collection of free online tools built for developers, designers, SEO specialists, and content creators. Every tool runs entirely in your browser — no data is ever sent to a server, no sign-up required, no tracking.
Why ToolMixr?
We got tired of online tools that:
- Force you to create an account just to format some JSON
- Upload your data to unknown servers for "processing"
- Bombard you with pop-ups, ads, and paywalls
- Break your workflow with slow, bloated interfaces
ToolMixr is our answer: fast, clean, private. That's it.
Who Built This?
Hi, I'm Lu Shen. I build web tools for a living — and I got frustrated enough with the existing options that I decided to build my own.
Before ToolMixr, I was that person with 15 browser tabs open, each running a different "free" tool that required an account, uploaded my data to some server I'd never heard of, or hit me with a paywall after two uses. So I built what I wanted: tools that just work, right in your browser, no strings attached.
I test every tool myself before publishing it. If a calculator gives me a wrong answer or a generator produces broken output, it doesn't ship. Period.
When I'm not building tools, I'm probably testing other people's AI tools over on GenAIPick, where I write honest reviews of AI products I actually pay for.
