Frequently asked questions
Is my file uploaded to a server?
No. The converter (FFmpeg compiled to WebAssembly) runs inside your browser, so the file never leaves your device. That also means there is no upload wait, even for big videos.
Why is the WAV so much bigger?
WAV stores every sample uncompressed, about 10 MB per minute for stereo, while MP3 uses heavy compression.
What sample rate is the WAV?
It keeps the source sample rate (usually 44.1 or 48 kHz) as 16-bit PCM, the most compatible kind of WAV.
