Frequently Asked Questions

How do I convert an MP3 to WAV?

Drop your MP3 onto the converter and press Convert. Solmi decodes the compressed audio and writes an uncompressed 16-bit PCM WAV at the same sample rate, which you can play here and download. Everything happens on your device.

Does converting MP3 to WAV improve the quality?

No, and it is worth being clear about this: MP3 encoding permanently discarded audio data, and decoding to WAV cannot bring it back. What you get is an uncompressed copy of the compressed audio — the right format for editing and for software that will not read MP3, but not better-sounding than the source.

Why would I want a WAV instead of an MP3?

Because a lot of software insists on it. Hardware samplers, CD burning tools, some video editors, and certain plugin formats either refuse MP3 or decode it unpredictably. WAV is also the safer working format when you plan to edit repeatedly, since it does not re-compress each time you save.

How big will the WAV file be?

Considerably bigger — uncompressed stereo audio at 44.1 kHz runs about 10 MB per minute regardless of the source bitrate. A four-minute MP3 of about 5 MB becomes a WAV of roughly 40 MB.

Are my files uploaded anywhere?

No. The converter runs entirely in your browser: your file is decoded and re-encoded on your own device, and nothing is sent to a server. That is also why it is fast — there is no upload wait and no download wait, just the conversion itself.

Is the converter free?

Yes, completely free with no signup, no file-size paywall, and no watermark. Once your audio is converted, you can turn the track into a music video with Solmi's AI music video generator — also free to start.
