How to use this tool
- Choose files or drag them into the workspace. Matching inputs get the output format shown on this page.
- Check the output format and image quality for each file. Existing files in your queue keep their settings.
- Start the conversion, then download individual results or the completed batch. Your original files are unchanged.
Quality and format notes
WAV stores uncompressed PCM audio, so files are large; MP3 compresses them to a fraction of the size with playback that works practically everywhere. Choose a lower bitrate for voice recordings and a higher one for music, then compare the results in the workspace.
MP3 is lossy, so the conversion cannot be undone; keep the original WAV as an archive copy. Unusual WAV layouts beyond standard PCM may fail to decode.
Frequently asked questions
Which bitrate should I choose for the MP3?
192 kbps suits most music and 128 kbps is fine for speech. Higher bitrates preserve more detail at the cost of larger files; the workspace reports each result's size so you can compare.
Will the MP3 sound identical to the WAV?
MP3 discards some audio data by design. Most listeners cannot tell the difference at higher bitrates on ordinary equipment, but archival and production work should stay in a lossless format.
Why is my WAV file so large?
WAV stores every sample uncompressed — roughly 10 MB per minute for CD-quality stereo. That makes it ideal for recording and editing, and impractical for sharing, which is what MP3 is for.
