About Sort123
Sort123 is a free online toolbox: 200+ fast, private tools that run in your browser — random pickers and classroom timers, calculators and converters, PDF, image and developer tools, and more. No sign-up, no file uploads, and most tools even work offline.
What we believe
Sort123 began in a classroom, where a teacher needed ten open browser tabs just to pick a student, make groups, run a timer and keep score. We built one calm, fast place for all of those small jobs — and it grew into a toolbox for teachers, coaches, offices, creators, accountants, analysts, writers, students, event planners and families, now available in 21 languages. The idea has never changed: tools that open instantly and disappear when your real work starts.
How we work
Free, no sign-up
Every tool is free and works the moment you open it. There are no accounts, no passwords and no paywalls.
Your data stays yours
The names, files and settings you enter stay only in your browser and are never uploaded. Microphone audio is processed on the spot and never recorded. You can read the details in our Privacy Policy.
Works anywhere, even offline
Sort123 runs on classroom projectors, laptops, tablets and phones, and can be installed as an app or added to the home screen. Once loaded, the tools keep working without an internet connection.
Built for real rooms
Big type, full-screen views, sound cues and screen wake locks are designed for projectors and the back row — and for a phone used one-handed. Random choices use the browser's cryptographic random generator, not a predictable dice roll.
The tools
There are over 200 free tools: name wheels and random pickers, timers and scoreboards, everyday calculators for money, dates, health and school; unit and currency converters; PDF, image and OCR tools that process files on your device; text and developer utilities; and printable worksheets, bingo cards and classroom aids. Browse them all on the home page.
