Frequently asked questions
Is the file uploaded to a server?+
No. Conversion runs inside your browser, so the file never leaves your device.
Can I convert losslessly?+
Yes. Convert to WAV or FLAC to save with no sound loss. MP3, M4A, and OGG are lossy formats that shrink the size.
Why is the first run a bit slow?+
It downloads the conversion engine once on first use. After that it runs faster.
