WAV to MP3 Converter

Convert WAV to MP3 online, free and private

This WAV to MP3 converter turns large, uncompressed WAV audio into compact MP3 files that play on every phone, computer, car stereo and music app. A WAV file is about 5–10 times bigger than the same audio saved as MP3, which makes WAV awkward to email, upload to a website or keep on a phone with little storage. Converting to MP3 solves that in a few seconds.

Unlike most online converters, VidHaul does not upload your file. The conversion happens inside your browser on your own device, so even a big studio recording does not have to travel over your internet connection, and private audio stays private.

How to convert a WAV file to MP3

1. Click Choose file at the top of this page, or drag and drop your .wav file onto the box.
2. Pick an MP3 bitrate: 128, 192 or 320 kbps. The default is 192 kbps.
3. Press Start and wait for the progress bar to finish.
4. Click Download. You will see the size before and after, so you know how much space you saved.

To change the next WAV to MP3, press Convert another file. There is no limit on how many files you convert.

How to convert WAV to MP3 on Windows 11, Mac or a phone

You do not need to install a program. On Windows 11, open this page in Edge, Chrome or Firefox. On a Mac, use Safari, Chrome or Firefox. On Android, use Chrome, and on iPhone use Safari or Chrome. The steps are the same everywhere. Phones are slower than laptops, and very large files (roughly over 1.5 GB) may be slow or fail on phones because the audio is processed in the device's memory.

WAV vs MP3: what is the difference?

WAV stores sound without compression. Every sample from the recording is kept, which is why audio editors, recorders and studio software often use it. The downside is size: a few minutes of WAV can take tens of megabytes.

MP3 uses lossy compression. It removes parts of the sound that people hardly notice and stores the rest very efficiently. The result is a much smaller file that plays almost anywhere.

WAV to MP3 conversion and audio quality loss

Because MP3 is lossy, a little detail is always removed when you convert WAV to MP3. How much you notice depends on the bitrate you pick:

• 320 kbps – the highest MP3 quality. Best for music and for anyone who wants to stay as close as possible to the WAV.
• 192 kbps – a good balance of quality and size for everyday listening.
• 128 kbps – the smallest file. Great for speech, interviews, voice notes and dictation.

Keep your original WAV if you might edit the recording later. Edit from the WAV and convert to MP3 as the final step; repeatedly converting an MP3 only loses more detail.

When to convert WAV to MP3

• Sharing a song or demo by email or chat, where big attachments are rejected.
• Saving space on your phone or laptop for a library of recordings.
• Uploading audio to a website or app that asks for MP3.
• Field and voice recordings from recorders that save WAV by default.
• Playing in the car or on older players that handle MP3 best.

Example: how much space can you save?

Standard CD-quality WAV uses roughly 10 MB for every minute of stereo sound. The same minute saved as MP3 at 192 kbps takes about 1.4 MB, and at 128 kbps less than 1 MB. So a 5-minute song of around 50 MB as WAV becomes roughly 7 MB as a 192 kbps MP3 – small enough to send in most chat apps. Exact sizes depend on how your WAV was recorded; after converting, the page shows the real size before and after.

Can I convert WAV to MP3 without losing quality?

Not completely, because MP3 always discards some data. In practice, 320 kbps keeps the result so close to the original that most people cannot tell them apart on phones, laptops or car speakers.

Why use this free WAV to MP3 converter?

It is free, has no sign-up and adds no watermark. There is no daily limit. It works in up-to-date Chrome, Edge, Safari and Firefox on computers and in Chrome or Safari on phones; very old browsers cannot run it and the page shows a message in that case. Speed depends on your device, but because nothing is uploaded, you do not wait for a large WAV to travel to a server and back.

More audio tools

Have an iPhone voice memo or a song in M4A format? Use the M4A to MP3 converter. To keep only part of your new MP3, for example a 30-second ringtone, open it in the MP3 cutter. And if the sound you need is inside a video, the video to MP3 converter or theMP4 to MP3 converter will extract it.

Please only convert audio you own or have the right to use.
