WHO WE ARE

About UToolsy

UToolsy is a collection of 22 free utilities that run entirely in your browser — nothing you open is ever uploaded.

Everything runs on your device

Most online tools work by sending your file to a server, processing it there, and sending it back. UToolsy does the opposite: every tool runs locally in your browser using web technologies like the Canvas API, WebAssembly, and Web Workers. Your images, PDFs, audio, and documents stay on your machine from start to finish.

Why we built it this way

Privacy shouldn't be a premium feature. When processing happens on-device, there are no uploads to intercept, no accounts to create, and no usage caps to hit. It's faster for you and cheaper for us to run — which is why every tool can stay free.

What's inside

22 tools across converters, calculators, image and media editors, and developer utilities — from Image to Text and Image Compressor to a Password Generator and JSON Formatter. New tools are added regularly.

A note on AI tools

A few tools (like the AI Image Upscaler and Voice to Text) download open-source AI models to your browser the first time you use them. The models are fetched from public CDNs, but your actual files are still processed locally and never leave your device.
