// THE FULL PICTURE

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.

// THE HONEST COMPARISON

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.
