What Is WAV?
WAV (Waveform Audio File Format) is a lossless, uncompressed audio format developed by Microsoft and IBM. It stores linear PCM (pulse-code modulation) samples — a literal numeric snapshot of the sound wave — so the audio is preserved exactly, with no compression and nothing thrown away.
Because it keeps the full waveform, WAV is the default working format in professional recording, music production, editing, broadcasting, podcasting and mastering. It opens natively in every digital audio workstation and never degrades, no matter how many times you save it.
Why Convert Audio to WAV?
Convert to WAV whenever you need maximum fidelity and editability. Lossy formats like MP3 and AAC re-compress every time you save, accumulating artifacts; WAV stays pristine through unlimited edits, making it the right format the moment audio enters a production pipeline.
Best WAV Settings Guide
The right WAV settings depend on what the audio is for. Pick a preset to apply a proven combination instantly, or fine-tune sample rate, bit depth and channels yourself.
Convert to WAV in 3 steps
Upload audio or video
Drag & drop, browse, paste or import from a URL. MP3, FLAC, AAC, M4A, OGG, MP4 and 25+ formats are supported.
Choose WAV quality
Pick a preset like CD, Studio or Mastering, or set sample rate, bit depth and channels manually. The estimator shows the output size live.
Convert & download
Press Convert to produce a lossless PCM WAV in your browser, then download it individually or as a ZIP.
Supported Audio & Video Formats
Convert any of these to lossless WAV — audio files directly, and video files by extracting their audio track.
WAV vs MP3 vs FLAC vs AAC
How does WAV compare with MP3, FLAC, AAC and AIFF for quality, size, editing and archiving? Here is a side-by-side breakdown.
| Format | Type | File size | Editing | Best for |
|---|---|---|---|---|
| WAVBEST | Lossless · uncompressed | Largest (~10 MB/min) | Excellent — no generation loss | Editing, mastering, archiving |
| FLAC | Lossless · compressed | Medium (~5 MB/min) | Excellent (decode overhead) | Hi-res libraries, storage |
| AIFF | Lossless · uncompressed | Largest (~10 MB/min) | Excellent | Apple/Logic workflows |
| AAC | Lossy · compressed | Small (~1 MB/min) | Poor — re-compresses | Streaming, mobile |
| MP3 | Lossy · compressed | Small (~1 MB/min) | Poor — re-compresses | Sharing, playback |
Sizes assume stereo audio at common settings (WAV/AIFF at 16-bit/44.1 kHz, MP3/AAC around 128–192 kbps). Your real numbers depend on bit depth, sample rate and bitrate.
Rule of thumb: work and master in WAV, archive in WAV or FLAC, and distribute in AAC or MP3. Convert to WAV whenever audio is about to be edited.
Common Reasons to Convert Audio to WAV
Podcast editing
Edit interviews and episodes losslessly, then export to MP3 only at the end.
Music production
Import stems and samples into your DAW as clean, full-quality WAV.
Video soundtracks
Deliver 48 kHz WAV audio to Premiere, Resolve and Final Cut.
Audiobooks
Produce normalized, mono narration ready for distribution platforms.
Archiving
Keep a lossless master you can transcode to any future format.
Restoration
De-noise, de-hum and EQ recordings in an uncompressed working file.
Broadcast
Hit EBU R128 loudness targets with normalized WAV deliverables.
Sampling / ML
Feed uncompressed PCM into samplers and audio models.

WAV Sample Rate Guide
Sample rate sets the highest frequency the file can store and strongly affects size. Higher is not always better — match it to the job.

WAV File Size Guide
WAV is uncompressed, so size is exactly sample rate × channels × bit depth × duration. These are typical per-minute sizes — the live estimator on the tool shows your exact projected size.
WAV Works in Every DAW & Editor
WAV is the universal interchange format for digital audio. It imports natively into every major workstation and video editor — no conversion plugin required.
Privacy First: No Upload, No Tracking
Unlike cloud converters that send your audio to a remote server, this tool processes everything locally in your browser. Your recordings stay yours.
How Audio Conversion Technology Works
What PCM and "uncompressed" actually mean
PCM stores the sound wave as a stream of evenly spaced amplitude measurements. WAV writes those numbers directly with no compression, so decoding is trivial and the data is identical to what was recorded — that is what makes it lossless and edit-safe.
How sample rate and bit depth shape quality
Sample rate sets how many measurements are taken per second (and therefore the highest frequency you can represent); bit depth sets how finely each measurement is quantised (and therefore the dynamic range and noise floor). Higher numbers mean more fidelity and larger files.
Why WebAssembly FFmpeg keeps your audio private
FFmpeg is the industry-standard media engine. Compiled to WebAssembly, it runs inside your browser tab, so your audio is processed on your machine. Nothing is uploaded, which is both faster and fundamentally more private than cloud converters.
Lossy source into a lossless container
When you convert an MP3 or AAC to WAV, the codec is decoded once and the result is stored losslessly. You will not regain detail that compression removed, but you stop the bleeding: no further generation loss occurs as you edit and re-save.
