Shrink oversized WAV files into MP3s you can actually send. Drop in a WAV and Solmi re-encodes it as an MP3 in your browser, typically cutting the file to around a tenth of its size while staying transparent at higher bitrates. No upload, no signup, no watermark.
Drop your WAV onto the converter, pick a bitrate if you want something other than the default 192 kbps, and press Convert. Solmi decodes the WAV and encodes an MP3 on your device, then offers it for playback and download.
A CD-quality stereo WAV runs about 1,411 kbps, so a 192 kbps MP3 is roughly a seventh the size and a 128 kbps MP3 roughly a eleventh. A five-minute song drops from about 50 MB to somewhere near 5–7 MB, which is what makes it emailable.
320 kbps for music you want as close to the source as MP3 gets, 192 kbps as the sweet spot for general listening and sharing, and 128 kbps when small size matters more than fidelity — podcasts, voice, or drafts. Higher bitrates mean bigger files and nothing else.
Yes, by design — MP3 is a lossy format and discards audio data to shrink the file. The gap from an uncompressed WAV is genuinely hard to hear at 192 kbps and above on typical gear. Keep the original WAV if the file is a master you will edit again later.
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.
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.
