WAV Converter, Convert Audio to Uncompressed WAV Online, In Your Browser
Drop an MP3, M4A, AAC, OGG or FLAC and get a clean, uncompressed PCM WAV, with the sample rate, 16- or 24-bit depth and channel layout you choose. Native Web Audio decoding, a waveform preview and an exact before/after size readout, all in your browser and never uploaded.
What is the wav converter?
The WAV Converter produces an uncompressed PCM WAV that every DAW, sampler, editor and game engine reads without a codec. Drop MP3, M4A, AAC, OGG or FLAC and choose the sample rate (44.1/48 kHz and up), 16- or 24-bit depth and mono/stereo. Preview the waveform, then download. Re-encoded natively in the tab, so nothing is uploaded.
The GigAI WAV Converter turns almost any audio your browser can decode into a standard uncompressed PCM WAV without ever sending your file to a server. WAV is the plain, lossless container that every DAW, sampler, editor, game engine and hardware device reads without complaint. No codec to install, no decode step, just raw audio ready to import. This tool decodes your source with the Web Audio API and re-encodes it natively in the tab, so there's no upload, no sign-up and no heavyweight download for the everyday case. Only genuinely exotic containers pull in an on-demand codec, and only for that one file. You're in control of the exact WAV you get: pick a sample rate (keep the original, or resample to 44.1 kHz for CD/streaming, 48 kHz for video and DAWs, 22.05 kHz for lightweight voice, or up to 96 kHz), choose 16-bit for maximum compatibility or 24-bit when you want extra headroom for further editing, and fold to mono or keep stereo. The moment you drop a file you see its waveform, duration, sample rate and channels. When the encode finishes you get the exact original and WAV byte sizes side by side, so the (usually much larger) size of an uncompressed file is never a surprise. Be honest with yourself about what a WAV can and can't do: converting a lossy MP3 or M4A to WAV gives you an editable, uncompressed file, but it can't recover detail the lossy encoder already threw away, WAV preserves what's there, it doesn't add quality back. Where it shines is when a tool demands WAV, when you need a clean master to edit or process, or when you want a format with zero decode ambiguity. Because everything runs on your device, sensitive recordings (interviews, unreleased stems, voice notes) never leave the tab. Close it and every byte is gone.

How to use the wav converter
- 1
Drop your audio
Drag an MP3, M4A, AAC, OGG, FLAC or other decodable file onto the workspace, or click to browse. It's read locally and you'll see its waveform, duration, sample rate and channels immediately.
- 2
Pick your WAV settings
Choose a sample rate (keep original or resample), 16- or 24-bit depth, and mono or stereo. Defaults keep the source rate at 16-bit, which suits most everyday needs.
- 3
Convert
Press Convert to WAV. Decoding and any resample run offline in your browser with a live progress bar, quick for short clips. Exotic inputs briefly load an on-demand codec the first time only.
- 4
Check the size & download
Read the original vs WAV size to see exactly what changed, preview the result, then download, or reset and re-run at a different rate, depth or channel layout.
What WAV Converter includes
Convert almost anything to WAV
Drop MP3, M4A, AAC, OGG, FLAC, WEBM or another WAV. If your browser can decode it, this re-encodes it to a standard uncompressed PCM WAV that every DAW, editor and device reads.
Choose the sample rate
Keep the source rate or resample: 44.1 kHz for CD and streaming, 48 kHz for video and DAWs, 22.05 kHz for lightweight voice, or up to 96 kHz. The resample runs offline in your browser.
16-bit or 24-bit depth
Pick 16-bit PCM for the widest compatibility and smallest size, or 24-bit when you want extra headroom for further mixing, mastering or restoration work before you commit.
Mono or stereo, your call
Keep the original channels or fold to a single mono track to halve the file, ideal for voice memos, interviews and anything where the stereo image doesn't matter.
Exact before / after size
WAV is uncompressed, so it's usually much larger than a lossy source. The tool shows the real original and WAV byte sizes side by side, so the delivery weight is never a surprise.
100% private, nothing uploaded
Decoding and encoding happen on your device. Interviews, unreleased stems and voice notes are never uploaded, stored or logged, there's no upload bar and no cloud copy.
Why use our wav converter
The format tools actually ask for
Samplers, DAWs, game engines, speech pipelines and old editors frequently demand a plain PCM WAV. Convert once and hand every one of them a file they'll open with zero fuss.
A clean, uncompressed canvas to edit
Editing repeatedly re-encodes a lossy file and stacks up artefacts. Working from an uncompressed WAV means every trim, fade and mix stays lossless until you export the final delivery format.
No upload wait, no privacy tradeoff
Server converters make you upload the file first and trust them with it. Here the audio never leaves your browser, so there's no upload bar and nothing to trust with a private recording.
You set the sample rate, depth and channels
Instead of accepting whatever a black box picks, you choose the exact WAV spec (48 kHz / 24-bit stereo for a DAW, 22.05 kHz / 16-bit mono for a small voice clip) and the size readout confirms it.
Built for the way you work
From quick one-off fixes to daily workflows, see how people put this tool to use.
- Music producer
Turn an MP3 stem into a WAV your DAW will import
Your session wants 48 kHz / 24-bit WAVs, but a collaborator sent an MP3. Decode it and re-encode a clean uncompressed WAV at the exact spec your project uses: without opening the DAW or uploading the stem.
- Sound designer
Prep samples for a sampler or game engine
A lot of samplers and engines only load PCM WAV at a specific rate. Convert clips to 44.1 kHz / 16-bit WAV in the browser so they drop straight into the instrument or asset pipeline.
- Podcaster / Editor
Make a lossless working copy before editing
Editing an MP3 repeatedly re-compresses it. Convert the recording to WAV first, cut and clean it losslessly, then export back to a compact format only for the final publish.
- Privacy-conscious user
Convert a private recording locally
An interview, a medical note or a confidential voice memo shouldn't be uploaded to a stranger's converter. Turn it into a WAV entirely in your browser so the audio never leaves the device.

MP3 vs WAV: Which Audio Format Should You Use?
ComparisonMP3 is the small, compressed format for listening and sharing. WAV is the uncompressed studio master for editing and production. Here's when to use each.
Read the comparisonWAV vs FLAC: Which Lossless Audio Format Wins?
ComparisonBoth WAV and FLAC preserve audio perfectly, but FLAC compresses to roughly half the size and tags cleanly. Here's when each lossless format is the right pick.
Read the comparisonCommon problems, solved
Hit a snag? Here are quick fixes for the issues people run into most.
My WAV file is huge.
That's expected. WAV is uncompressed, so a few minutes of stereo 24-bit audio is many megabytes. To shrink it, drop to 16-bit, fold stereo to mono, or resample to a lower rate. If you don't specifically need WAV, a 192 kbps MP3 is a fraction of the size (see the MP3 Converter).
The WAV doesn't sound better than the MP3 I converted.
It won't. Converting a lossy source (MP3/M4A) to WAV gives you an uncompressed, editable file, but the detail the lossy encoder discarded is gone for good. WAV preserves what's there, it can't restore quality. For the best result, convert from a lossless source (FLAC or an original WAV) whenever you can.
My file wouldn't load or decode.
The converter can only handle audio your browser can decode. Most MP3, M4A/AAC, OGG, WAV and (on most browsers) FLAC files work. A DRM-protected purchase, a raw/exotic codec or a corrupt file may not. Try re-exporting the source to a common format first, then convert that to WAV.
The tab got slow or ran out of memory on a very long file.
Encoding holds the decoded, uncompressed audio in memory, and WAV is the heaviest output there is. Close other heavy tabs and try again. For very long recordings, trim first (see the Audio Trimmer), drop to 16-bit/mono, or convert in shorter sections.
Get the most out of it
Match your project's spec: 48 kHz / 24-bit for most video and DAW work, 44.1 kHz / 16-bit for CD, streaming and general compatibility.
Resampling to a HIGHER rate than the source (e.g. an MP3 at 44.1 kHz up to 96 kHz) grows the file without adding real detail, only up-sample when a target device or tool actually requires that rate.
For voice-only content, 22.05 kHz / 16-bit mono makes a dramatically smaller WAV that's still perfectly clear for speech.
Keep 16-bit unless you'll do further mixing or restoration: 24-bit gives editing headroom but doubles nothing you can hear on a finished, unedited file.
Watch the before/after size readout before you download so a large uncompressed WAV never catches you out on a slow connection or a storage cap.
