Instant Browser Decoding

For videos under 50MB, your browser's native audio engine decodes the video and re-encodes the audio as WAV in milliseconds — no upload whatsoever.

Fast Server Extraction

Our backend uses the -vn (no video) optimization to skip frame decoding entirely. Only the audio stream is processed, making it dramatically faster than full transcoding.

4 Output Formats

Choose MP3 for universal compatibility, WAV for lossless editing, AAC for high quality at small size, or FLAC for lossless archival with compression.

Frequently Asked Questions

For video files under 50MB, your browser decodes the audio track using the native Web Audio API and re-encodes it as a WAV file. Everything happens locally — no upload, no server, instant result.

Browser APIs can natively decode audio PCM data and encode it as WAV. Encoding to MP3, AAC, or FLAC requires complex codec implementations that must run server-side via FFmpeg for accuracy and speed.

Uploads are streamed in 2MB chunks to prevent memory spikes. FFmpeg uses the -vn flag to skip video frame decoding entirely, extracting only the audio stream at maximum speed. Jobs are queued to prevent server overload.

MP3 is best for podcasts, music, and sharing. WAV is ideal if you need lossless audio for further editing. AAC offers better quality than MP3 at the same file size. FLAC is perfect for archival — lossless but compressed.
