Convert browser-supported audio to MP3, WAV or FLAC with bitrate, mono, volume and batch ZIP controls.
Get started
Choose up to five MP3, WAV, M4A, AAC, OGG, FLAC or WebM files your browser can decode.
Select MP3, WAV or FLAC output. Adjust bitrate, mono mixing and volume if needed.
Convert, listen to the results and download files individually or as a ZIP.
Know the limits
20 MB per input, 80 MB combined, five minutes each and 80 MB combined output. Browser decoding varies. All output is 44.1 kHz; WAV/FLAC use 16-bit PCM. No M4A/OGG export, DRM bypass, metadata preservation or recovery of lost detail. FLAC is lossless relative to processed PCM. Larger conversions may strain mobile memory.
Try the workflow
Keep your original documents and review the output. You can also browse all guides or contact Team Hypomnema.
