What you can do with audio.

Audio format conversion is one of those tasks that sounds simple until you actually need to do it. Your recording software exports WAV but you need MP3. Your client sent FLAC files but your editor only takes WAV. Your phone recorded M4A but the submission portal only accepts MP3.

fwip converts between 8 audio formats — MP3, WAV, FLAC, M4A, AAC, OGG, WMA, and AIFF. You can also trim audio with a visual waveform editor, or extract lossless audio from any video file. Everything runs on ffmpeg.wasm in your browser.

Lossless-to-lossless conversions (FLAC to WAV, AIFF to WAV) preserve full quality. Lossy conversions (WAV to MP3) let you choose your bitrate.

Why this is different.

Most online audio converters upload your file, process it on a server, and send back the result. That's slow for large files and means your audio — voice memos, recordings, interviews, music — passes through third-party infrastructure.

fwip converts audio entirely in your browser. The ffmpeg.wasm engine runs locally, so your files stay on your device. No upload progress bars, no server queues, no risk of your audio being stored or logged.

The offline bundle handles batch conversions and removes file size limits.

Frequently asked.

Do my audio files get uploaded to a server?
No. All processing happens in your browser using FFmpeg compiled to WebAssembly. Your audio files never leave your device.
What audio formats are supported?
MP3, WAV, FLAC, OGG, AAC, M4A, WMA, and AIFF. You can convert freely between any format.
What quality options are available?
MP3 conversion supports 128, 192, 256, and 320 kbps. WAV and FLAC are lossless. The trim tool uses a visual waveform editor for precise cutting.
Does converting MP3 to WAV improve quality?
No. Converting lossy to lossless preserves what's there but doesn't restore lost data. It's useful when a tool requires WAV input.
What bitrate does fwip use for MP3?
192kbps by default, which balances quality and file size. Good enough for voice and most music.
Can I extract audio from a video without re-encoding?
Extract WAV pulls lossless audio from any video. MP4 to MP3 converts to compressed MP3.
