FLAC preserves the original audio without lossy compression. MP3 is smaller and more compatible, but it discards some audio information. The right workflow is to keep FLAC as the master copy and export MP3 versions for phones, players, uploads, or sharing.
Use 192k for everyday listening, 256k when you want a stronger quality target, and 320k when compatibility matters but you want the highest common MP3 bitrate. Lower bitrates are useful for voice or when file size matters more than music fidelity.
The FLAC decode and MP3 encode steps run inside your browser with FFmpeg.wasm. That keeps private recordings, stems, interviews, or music drafts on your device instead of uploading them to a conversion service.
No. FLAC is lossless and MP3 is lossy, so some detail is discarded. Use 256k or 320k when you want a smaller file while preserving more audible quality.
Yes. Choose 128k for smaller files, 192k as a balanced default, or 256k/320k when quality matters more than file size.
No. The FLAC is decoded and encoded locally in the browser with FFmpeg.wasm, and the MP3 is created as a local download.
Yes, if you care about archival quality. Treat the MP3 as a portable copy for sharing, car stereos, phones, or apps that do not handle FLAC well.
