Convert between MP3, WAV, AAC, OGG, FLAC, and M4A — or pull the audio out of any video. 100% in-browser.
Drop an audio or video file, pick a format, and convert it locally
Audio conversion runs entirely in your browser using ffmpeg.wasm. Your file is never uploaded to any server.
Lossy formats (MP3, AAC, OGG, M4A) discard sounds your ears are least likely to miss — a 192 kbps MP3 keeps roughly one-tenth of the original CD data. Lossless formats (WAV PCM, FLAC) store every sample exactly: WAV uncompressed at ~1,411 kbps, FLAC compressed at 50–70% of that with zero loss. Converting lossy → lossless never restores discarded data (garbage in, bigger garbage out), so use WAV/FLAC when you have a lossless source, and MP3/AAC 192–320 kbps when size matters. Dropping a video file here extracts its soundtrack with -vn — the same engine as the Audio Extractor.
Bitrate only applies to lossy targets; WAV and FLAC ignore it because they keep every sample.

Convert audio to 6 formats with bitrate control, or extract audio from video. Everything runs locally; nothing is uploaded.
FreeToolHub Audio Converter is a free browser-based tool — convert audio to 6 formats with bitrate control, or extract audio from video. No signup, no upload; everything runs locally in your browser.
Convert audio to 6 formats with bitrate control, or extract audio from video. In-browser.
The Audio Converter decodes any audio or video file locally with ffmpeg.wasm and re-encodes it to one of six formats. Lossy targets (MP3, AAC, OGG, M4A) offer 128–320 kbps bitrate control; lossless targets (WAV, FLAC) keep every sample. Dropping a video extracts its soundtrack automatically.
Drop your file, pick the output format (and bitrate for lossy formats), and click Convert. The result card shows the output size and an inline player so you can check quality before downloading.
Format choice follows the destination. MP3 remains the universal default — every device, car, and app plays it, and at 192-320 kbps it is transparent for most listening. WAV is the lossless archive format: no compression at all, ideal for further editing, at roughly ten times the size. AAC delivers better quality than MP3 at the same bitrate — the right pick when Apple ecosystems dominate. OGG and FLAC serve specific niches: open-source-friendly streaming and true lossless compression respectively. Bitrate is the quality dial inside lossy formats: 128 kbps suits speech and podcasts, 192 kbps is solid for music, and 320 kbps is the transparent ceiling — above it, size grows with no audible gain. Conversions run locally with WebCodecs, so a large library converts without upload queues, and extracting a soundtrack from a video is the same pipeline with the video track dropped.
Six outputs: MP3, AAC, OGG, and M4A at 128–320 kbps for lossy sharing, plus WAV (uncompressed 16-bit PCM) and FLAC (lossless compression) for editing and archiving. The bitrate selector only appears for lossy formats because WAV and FLAC keep every sample regardless.
Yes — drop an MP4, WebM, or MOV and the tool strips the video track (-vn) and converts the soundtrack to your chosen format. That makes this converter a one-stop audio extractor as well.
No. Converting MP3 to WAV or FLAC never restores the data the MP3 encoder discarded — you get a bigger file with the same audible quality. Use lossless output when your source is already lossless; use 192–320 kbps lossy when size matters.
WAV when the file faces further editing or archival (lossless, large); MP3 for distribution and listening (universal, small). A practical pattern: convert to WAV for your master copy, MP3 320 kbps for sharing — this tool produces either directly.
320 kbps for music if storage is no concern — it is transparent to nearly all listeners. 192 kbps is the practical sweet spot with no perceptible loss for most material. 128 kbps is fine for speech and podcasts, where source quality is lower anyway.
