Convert
WAV to MP3
Convert WAV audio to MP3. You are starting from WAV, which is uncompressed PCM: perfect fidelity at roughly 10MB per minute. MP3 is the safe default: every player built in the last 25 years reads it. WAV is lossless and MP3 is lossy, so this discards audio data in exchange for a much smaller file. Runs on your own Vistalyth Tools instance. Files never reach a third party.
Features
- Bitrate and sample rate control
- Tags, artwork, and track metadata carried across wherever MP3 supports them

What you can do

Self-hosted. Your files never leave your network.
Vistalyth Tools runs entirely on your own infrastructure. Files processed with WAV to MP3 are never uploaded to third-party servers. Deploy a single Docker container and process files with full privacy, no watermarks, and no usage limits. Open source under AGPL-3.0.
Frequently asked questions
- Will WAV to MP3 lose quality?
- Some, unavoidably. Pick a bitrate you are happy to live with, because the discarded detail is gone for good and re-encoding upward later recovers nothing.
- Are tags and cover art kept?
- Yes, wherever the target has somewhere to put them. MP3 carries the common fields; anything exotic in the source may not survive.
- Anything peculiar about WAV I should know?
- WAV has no standard tag block, so artist and title fields most likely do not exist in the source to carry over.
- Can I convert a whole folder at once?
- Yes. Batch conversion applies the same settings to every file and returns them together.
