About Toolmingo
Toolmingo is a collection of free online tools that do one thing really well: get the job done without getting in your way.
Private by design
Most online tools upload your files to a server. We don't. Every Toolmingotool runs entirely in your browser, which means your images and documents never leave your device. It's faster, safer, and works even on a flaky connection.
Free, forever
No accounts, no watermarks, no upload limits. Toolmingo is supported by unobtrusive ads so the tools can stay free for everyone.
