ToolBurst is a free online tools platform built on a simple idea: your tools should run in your browser, not on someone else's server. That means every utility on this site — converters, formatters, compressors, encoders, decoders, validators, generators, and calculators — runs 100% client-side. No uploads, no tracking, no data collection, and no sign-up. Just open a tool and use it instantly, anywhere in the world.

What started as a handful of utilities has grown into a 27-tool toolkit used worldwide across Europe, North America, South America, Asia, Africa, and Oceania. Whether you are in Stockholm, London, Berlin, New York, San Francisco, Bangalore, São Paulo, or Sydney, ToolBurst gives you fast international access to secure online tools on desktop and mobile.

Every tool here is open source under the GPL-3.0 licence and built to respect your privacy first. Whether you're compressing an image, formatting JSON, or generating a secure password, your data never leaves your device.
