What is a WAV file?
WAV is the uncompressed audio format of Windows and of most recorders, audio interfaces and editing programs. One minute of CD-quality stereo takes about 10 MB, so a one-hour recording can exceed 600 MB. Converting a WAV to MP3 divides the size by 5 to 10 while keeping a sound that is indistinguishable for most listeners at 192–320 kbps.
Since WAV is lossless, it is the ideal source for an MP3: you go through only one round of compression. Keep the original WAV if you may edit the recording later.
Why convert to MP3?
MP3 is the most compatible audio format ever made: it plays on every phone, computer, car stereo, smart TV, smart speaker and MP3 player, without exception. Its compression removes sounds the ear barely perceives, giving files about ten times smaller than CD quality. At 192 kbps it is transparent for most listeners; at 320 kbps it is the best MP3 can do. Choose MP3 when you do not know where the audio will be played – it will always work.
Tips for WAV files
- For music from a studio or a mixing session, choose 320 kbps.
- For voice memos and interviews recorded in WAV, 128 kbps is enough.
- WAV files over 100 MB (about 10 minutes of stereo) must be cut first, or converted with FFmpeg.
Which audio format should you pick?
| Format | Type | Size for 1 min | Best for |
|---|---|---|---|
| MP3 | Lossy, universal | ≈ 1.4 MB at 192 kbps | Everything: phones, cars, speakers, music players |
| M4A | Lossy (AAC), efficient | ≈ 1.4 MB at 192 kbps | iPhone, iPad, Apple Music, Android |
| WAV | Uncompressed (PCM) | ≈ 10 MB | Audio editing, DAWs, CDs, transcription tools |
| FLAC | Lossless, compressed | ≈ 5–7 MB | Archiving, hi-fi listening, editing |
| OGG | Lossy (Vorbis), open | ≈ 1.4 MB at 192 kbps | Games, Linux, open-source projects |
| OPUS | Lossy, most efficient | ≈ 1 MB at 128 kbps | Voice, podcasts, small files, web |
WAV to MP3: frequently asked questions
Is the WAV to MP3 converter free?
Yes. Videos-to-MP3 is completely free: no subscription, no watermark, no limit on the length of the audio. The only limits are 100 MB per file and a fair-use cap of 60 conversions per hour.
Will the MP3 file lose quality?
The audio is taken directly from the original track. With a high bitrate (or a lossless format such as WAV or FLAC) the difference is inaudible. A converter can never add quality that was not in the source, so a low-quality video will give a low-quality audio file.
Can I convert WAV to MP3 on my phone?
Yes. The converter runs in Safari, Chrome, Firefox, Samsung Internet and Edge. On iPhone, tap “Choose files”, pick the video from Photos or Files, then save the result with the download button.
Are my files kept on your server?
No. Each file is processed in a private temporary folder and deleted as soon as the MP3 file has been sent back to you. Nothing is published or shared.
What if my WAV file is bigger than 100 MB?
Use the trim options of your phone’s video editor or a free tool such as VLC or HandBrake to cut it into parts, or extract the audio locally with FFmpeg (see our FFmpeg guide).
