Frequently asked questions
Is my video uploaded to a server?
No. The conversion runs inside your browser using a WebAssembly version of FFmpeg, the same engine professional video tools use. Your file never leaves your device.
Why does it take longer than desktop software?
It runs on a single processor core inside your browser, so re-encoding is slower than native apps. Conversions that can copy the original streams (no re-encoding) take only seconds.
Why is the WAV file so big?
WAV is uncompressed: about 10 MB per minute of stereo audio. Use MP3 or M4A for sharing.
