How to convert Audio to MP3

  1. 1

    Choose your Audio files

    Click the upload area or drag files onto it. Nothing is uploaded — files are opened locally.

  2. 2

    Adjust the settings

    Pick output format and audio quality, then press the convert button.

  3. 3

    Download the result

    Save each file individually or everything at once as a ZIP.

One converter for every audio format, including the awkward ones like WMA and AIFF. Pick the output format and quality; video files are accepted too and their soundtrack is extracted.

What is Audio?

MP3, WAV, M4A, FLAC, OGG and AAC audio — and the soundtrack of video files — are supported as input.

What is MP3?

MP3 is the universal compressed audio format. It plays on every device, car stereo and music app with small file sizes.

Is it private?

Yes. Unlike upload-based converters, ZapMorph processes files inside your browser tab, so the file stays on your device. It is never transmitted, stored or logged — close the tab and it’s gone.

Frequently asked questions

Is the audio converter free?

Yes, once a day. Convert one file up to 25 MB a day without an account. A free account gets one run a day on any Pro tool with files up to 50 MB; Pro and Lifetime plans are unlimited.

Are my files uploaded to a server?

No. The conversion runs entirely in your browser, so your files never leave your device. We only count how many files you convert — never their names or contents.

What is the maximum file size?

Up to 25 MB per file without an account, 50 MB with a free account, and 1 GB on Pro. Very large files also depend on your device’s memory.

Can I convert multiple Audio files at once?

Yes. Select several Audio files at once — up to 5 on the free plan or 50 on Pro — and download all results in a single ZIP.

Does it work on Mac, Windows, iPhone and Android?

Yes. It works in any modern browser — Chrome, Edge, Firefox and Safari — on desktop and mobile, with nothing to install.
