When WAV Is the Right Choice Over MP3
MP3 is great for listening, but WAV is the format professionals reach for when quality and editability matter. If you are working with audio rather than just playing it back, converting MP4 to WAV is usually the smarter move.
Audio Editing and Post-Production
Audacity, Logic Pro, Pro Tools, FL Studio, DaVinci Resolve — every serious audio editor works best with uncompressed WAV files. Convert your MP4 to WAV before importing into a DAW, and you start with the cleanest possible source. No MP3 compression artifacts creeping into your edits.
Sampling and Sound Design
Pulling a sound effect, a vocal snippet, or a music loop from a video clip? WAV preserves every detail of the original waveform, which matters when you are slicing, pitching, or layering samples. Converting MP4 to WAV gives you raw material that holds up under heavy processing.
Lossless Archiving of Important Audio
Interviews, field recordings, oral histories, legal depositions — when the audio content is irreplaceable, you want a lossless copy. Extracting WAV from MP4 means the archived audio is bit-for-bit faithful to the original track, with no generational quality loss if you ever need to re-encode later.
Why Use This MP4 to WAV Converter
Most free converters default to MP3 and bury the WAV option, or they re-encode through a lossy step before giving you the output. This tool is built with WAV in mind.
True Uncompressed WAV Output
The converter extracts the audio stream from your MP4 and writes it to a standard PCM WAV file — no intermediate lossy step. What goes in is what comes out. This is the way to convert MP4 to WAV when quality is non-negotiable.
Local Processing — Nothing Uploaded
WAV files can be large, and uploading them to a server wastes time and bandwidth. This MP4 to WAV converter does all the work inside your browser, so you skip the upload entirely. Faster results, total privacy.
Fast Even for Long Videos
Because the conversion runs on your own hardware, there is no server queue. A 10-minute MP4 produces a WAV in seconds. Even hour-long recordings convert quickly since the bottleneck is just the audio decode, not a network upload.
Batch Convert Multiple MP4 Files
Recording sessions, interview clips, field recordings — drop a whole stack of MP4 files in and convert them all to WAV at once. Download individually or grab the full set as a ZIP.
Works in Any Browser, Any OS
No need to install Audacity or FFmpeg just to extract a WAV. Open videotoaudio.net on Windows, Mac, Linux, or even a Chromebook and convert MP4 to WAV right there. If the browser runs, the converter runs.
Free — No Limits, No Account
Convert as many MP4 files to WAV as you need without creating an account or hitting a paywall. No file-size caps, no daily conversion limits, no watermarks on the output.
How to Convert MP4 to WAV
The workflow is dead simple — even if you have never touched an audio converter before.
Drop Your MP4 Into the Converter
Open videotoaudio.net and drag one or more .mp4 files onto the page. You can also tap the upload area to pick files from your device. The converter reads any standard MP4 container.
Select WAV as the Output
Choose WAV from the format menu. Unlike lossy formats there is no bitrate to configure — WAV is uncompressed by nature, so what you get is a faithful copy of the original audio track.
Download the WAV File
Hit convert. The audio is extracted and packaged as a .wav file within seconds. Save it to your project folder, import it into your DAW, or archive it for safekeeping. For batch jobs, use the ZIP download.

MP4 to WAV — Frequently Asked Questions
Why would I choose WAV over MP3 when converting from MP4?
WAV is uncompressed, so it preserves every detail of the audio. Choose WAV when you plan to edit the audio in a DAW, use it as a sample, or archive it for long-term storage. MP3 is better when small file size and casual listening are the priority. If you are not sure, start with WAV — you can always convert WAV to MP3 later, but you cannot go the other way without losing quality.
How large is the WAV file compared to the original MP4?
WAV files are significantly larger than compressed audio formats. A 5-minute stereo WAV at CD quality (44.1 kHz, 16-bit) is about 50 MB. The MP4 video might be 100 MB total, but its compressed audio track could be only 3–5 MB. So the extracted WAV is bigger than the compressed audio inside the MP4, but much smaller than the video itself.
Is the WAV output truly lossless from an MP4 source?
It depends on what is inside the MP4. Most MP4 files contain AAC audio, which is already lossy-compressed. The converter decodes that AAC to uncompressed PCM WAV without adding any additional quality loss. You get a perfect, uncompressed representation of the audio that was in the MP4 — but it cannot restore detail that the original AAC encoding removed.
Can I import the WAV directly into Audacity, Logic Pro, or Pro Tools?
Yes. The converter produces standard PCM WAV files that every major audio editor recognizes natively. Just drag the .wav into your project timeline. No format conversion plugins or import steps needed.
What sample rate and bit depth does the WAV use?
The converter matches the sample rate and bit depth of the original audio track in the MP4. If the source audio is 44.1 kHz 16-bit, the WAV will be 44.1 kHz 16-bit. If it is 48 kHz (common in video), the WAV will be 48 kHz. No unnecessary up-sampling or down-sampling.
Can I convert MP4 to WAV on a phone or tablet?
Technically yes — the converter runs in any modern mobile browser. Just keep in mind that WAV files are large and can fill up phone storage quickly. For a quick extraction it works fine, but for long recordings or batch conversions a laptop or desktop with more storage space is more practical.
Is WAV the same thing as WAVE?
Yes. WAV and WAVE refer to the same format — Waveform Audio File Format. The file extension is .wav. Whether a tool calls it WAV or WAVE, it is the same uncompressed PCM audio container.
Should I use WAV or FLAC for archiving audio from video?
Both are lossless and preserve full audio quality. WAV is simpler and universally supported by every audio tool. FLAC adds lossless compression so files are about 50–60% the size of WAV. For active editing, WAV is usually more convenient. For long-term storage where disk space matters, FLAC is a good alternative.
Can I convert a long MP4 — like a full lecture or movie — to WAV?
Yes, but be aware of file sizes. A two-hour audio track at CD quality produces a WAV of roughly 1.2 GB. Make sure you have enough free disk space before starting. The converter itself handles any duration — the only limit is your device's available storage and memory.
What if I need WAV from a video format other than MP4?
videotoaudio.net supports many video formats beyond MP4 — including AVI, MOV, MKV, WEBM, FLV, and MPEG. Use the main Video to Audio converter at the homepage to convert virtually any video file to WAV.
