WAV Converter
FileFlip converts WAV files into 11 other formats entirely inside your browser, using WebCodecs and FFmpeg compiled to WebAssembly. The WAV file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. There is no file-size limit and no account to create.
How do I convert a WAV file?#
- Drop your WAV file onto the converter at the top of this page, or click it to pick one from your computer.
- Choose the format you want out of it. FileFlip downloads the engine that conversion needs, once, and your browser caches it.
- Conversion starts the moment you pick the format, and the result is yours to download. The work happens in this tab, so nothing is uploaded and nothing is queued.
Is it safe to convert WAV files online?#
Yes, because nothing is uploaded. FileFlip converts WAV files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.

What is a WAV file?#
A WAV file holds digital audio, almost always uncompressed PCM samples, wrapped in Microsoft and IBM's RIFF chunk structure, the same sample encoding used on audio CDs.
Use WAV for recording, editing and mixing, where uncompressed audio and broad software support matter more than file size.
Convert WAV to MP3 or FLAC once editing is finished and the file needs to be distributed, since raw PCM is unnecessarily large for listening rather than production.
The WAV file format reference covers the specification, the programs that open one, and what each conversion keeps or drops.
WAV questions people ask#
Is WAV a lossless format?
Yes, WAV is lossless in the sense that matters for audio: it stores uncompressed PCM samples with nothing removed and nothing approximated. It isn't compressed at all, so there's no algorithm that could introduce loss, unlike FLAC, which compresses the audio but still decodes back to the exact same samples.
Why are WAV files so much bigger than MP3s?
WAV files are bigger than MP3s because WAV stores every audio sample uncompressed, while MP3 discards sound and compresses what's left to about a tenth of the size. A three-minute song runs roughly 30 MB as CD-quality WAV versus 3-5 MB as a 192 kbps MP3.
Does converting WAV to MP3 lose quality?
Yes, converting WAV to MP3 loses quality, because MP3 is a lossy codec that permanently discards audio data during encoding. The loss is usually inaudible at 256-320 kbps, but it is real and can't be undone by converting the MP3 back to WAV.
What plays WAV files?
Every mainstream media player and DAW plays WAV files: Windows Media Player and VLC on Windows, QuickTime Player and Music on macOS, and Audacity, Pro Tools, Logic and Ableton Live everywhere audio gets edited. Support is effectively universal because the format has been the audio industry's baseline since 1991.
Can a WAV file contain compressed audio?
Technically yes: the WAV container can hold compressed formats like ADPCM through its format-tag system, a leftover from Microsoft's old Audio Compression Manager. In practice almost every WAV file in circulation holds uncompressed PCM, which is what people mean when they call WAV an uncompressed format.
