Converting WAV audio to MP3

Morphr decodes your WAV and re-encodes it as MP3, a compact format that plays just about everywhere. If the source was already lossy, going from one lossy format to another can’t bring back detail the first encoder removed.

WAV and MP3, explained

WAV is uncompressed PCM audio — the raw, lossless studio format. Files are large but hold the exact waveform. MP3 is the universal lossy audio format, playable on every device. It shrinks sound to a fraction of its size at a quality that is hard to fault for everyday listening.

Good to know

• • Your WAV files never leave your device — everything converts locally in the browser, so even confidential ones stay private.
• • Convert as many WAV files as you like at once; a batch comes back as a single ZIP.
• • No sign-up, no watermark and no size limit beyond your device’s memory.

The private way to turn WAV into MP3

With Morphr, the whole conversion runs inside your browser tab using your browser's built-in decoder, so your file is never uploaded to a server, queued, or stored. That makes it a safe choice for personal photos, scanned documents and anything you'd rather not hand to a third party.

Frequently asked questions

How do I convert WAV to MP3?

Drop your WAV file onto the converter above (or click to browse), and Morphr converts it to MP3 right in your browser. When it's done, click download — there's nothing to install and no account to create.

Will my formatting be preserved in MP3?

Your text and core formatting — headings, bold, lists and links — carry across. Things like multi-column layouts, text boxes and precise spacing may be flattened.

Are my files uploaded to a server?

No. The conversion runs entirely in your browser, so your WAV file never leaves your device.
