Features
Six Target Formats, One Tool
Pick from MP3, WAV, AAC, OGG, FLAC and M4A — whichever your player, editor or podcast host expects. One upload, any target.
MP3 & AAC for Sharing
High-quality MP3 (~190 kbps) and AAC (128 kbps) — the two formats every device, streaming service and messaging app plays natively.
WAV & FLAC for Archival
Lossless WAV (16-bit / 44.1 kHz) and FLAC for editing, mastering or preserving original quality with zero quality loss.
OGG & M4A for Flexibility
OGG Vorbis for open-web use, M4A (AAC in MP4) for iOS, Apple Music and iTunes workflows — both first-class here.
Video In, Audio Out
Drop a video file (MP4, MOV, MKV, WebM, AVI) and convert its audio track directly — no separate extraction step needed.
Unified Workflow
Whether your source is an MP3 or a lecture recording in MP4, the converter strips video and converts audio to your target format in one pass.
Container Auto-Detect
The converter reads the source file, detects the audio stream, and converts it to your chosen format — no format guessing required.
Batch-Friendly
Convert one file per page load — but the interface is built for quick iteration: upload, convert, download, repeat.
100% Private & Free
Your audio never leaves your device. All conversion runs right in your browser tab, on your own device — no server, no upload, no tracking.
Zero Server Upload
Files are read, converted and written back entirely on your own machine. We never see your audio or the output.
No Watermark
Clean output — no audio intro, no brand tag, no metadata injected. Your audio, untouched.
Works Everywhere
Any modern browser on any device — Chrome, Firefox, Safari, Edge, desktop or mobile.
