Frequently asked questions
How much quality do I lose?
At ~190 kbps VBR the difference from WAV is inaudible to the vast majority of people and gear.
Why does the first conversion take a moment to start?
On first use the ffmpeg engine (about 32 MB) is downloaded from this same site; it stays cached afterwards. The conversion itself depends on video length and your hardware.
Are metadata kept?
WAVs barely carry metadata; the MP3 comes out clean for you to tag.
Is there a size limit?
The site-wide limit is 250 MB per file, and above 100 MB we warn it may be slow: everything is processed in your browser memory.
