Keep the original WAV
Many WAV files contain uncompressed PCM audio. MP3 discards information: use it as a distribution copy and keep the original for editing. Size savings depend on the source encoding and chosen bitrate.
File processing
The file is uploaded and processed on the server. Processing deletes the original when it finishes; the MP3 is deleted after a complete download or through temporary-file cleanup. Technical conversion data is logged.
Frequently asked questions
Can I recover the original WAV from the MP3?
No. Saving an MP3 as WAV cannot restore data discarded during compression.
How large will the copy be?
Size mainly depends on duration and total bitrate. The size calculator provides an estimate, not a measurement of the file you will generate.
