About
This site converts images between formats without ever sending them to a server. Everything runs inside your browser.
Why build it this way
Most online converters work by uploading your file, processing it on a server, and sending the result back. That means a copy of your photo sits on someone else’s machine, at least briefly, and you have to take their word for what happens to it afterwards.
Browsers can now do this work themselves. Image codecs compiled to WebAssembly run at close to native speed on your own processor, which removes the need for a server entirely. No upload, no copy, nothing to retain.
How to verify the claim
You do not have to trust us on this. Open your browser’s developer tools, switch to the Network tab, and convert a file. You will see no outbound request carrying your image.
A stronger test: load the page, disconnect from the internet, then convert a file. It still works, because everything needed is already in the page.
What it costs
Nothing. There is no account, no watermark, and no daily limit. Because the conversion runs on your device rather than our servers, the marginal cost of each conversion is zero for us.
The site is supported by advertising. If that ever stops covering the hosting bill, we would rather show more ads than start charging or start uploading files.
