Converting MP3 files privately

frogConvert runs the conversion engines in your browser as WebAssembly, so a MP3 file is read, converted and saved without ever being sent anywhere. That matters most for the files people are least willing to upload: contracts, medical records, unreleased work, anything under an NDA.

It also means the converter works offline. Once the page has loaded, you can turn off the network and keep converting.

Common questions

Can I open a MP3 file without installing anything?
Yes. frogConvert reads MP3 files directly in the browser and converts them to a format you already have software for. Nothing is installed and nothing is uploaded.
Are my MP3 files uploaded to a server?
No. Every conversion runs locally in your browser through WebAssembly. There is no server to send files to, and the app keeps working with the network disconnected.
