ToolHoney is a free library of online tools, calculators, converters and generators. Every tool runs in your browser, on its own page, with its formula, a worked example and answers to common questions.
What you get here:
- 2,017 free tools across 19 categories — finance, fitness and health, PDF tools, image tools, math, converters, text and developer tools, date and time, and more.
- No sign-up, no downloads, no paywall.
- File tools (PDF, image and document tools) process your files in your own browser wherever possible, so your files stay private.
The site is in English right now. Spanish, Portuguese, French, German and Indonesian versions are planned for a later phase.
