Why “Privacy-First”?

Most online tools (TinyPNG, CloudConvert, and countless “free” sites) upload your files to their servers to process them. That means your private photos, documents, and data sit on someone else’s machine — subject to their retention policy, their security, and their terms.

These tools work differently. They use modern browser APIs (Canvas, Web Crypto, File API) to do all the work locally, on your device. Nothing is uploaded. You can even disconnect from the internet after the page loads and they keep working. Read the full reasoning →
