Frequently Asked Questions
Clear answers regarding conversion, privacy, and technical capabilities.
How much smaller will the MP3 file be compared to WAV?
A standard WAV file is uncompressed PCM audio (around 10 MB per minute). Converting to a 192 kbps MP3 reduces the file size by approximately 85% to 90% with virtually no audible loss.
Are any audio frequencies lost during conversion?
MP3 uses psychoacoustic perceptual coding. At 256k and 320k bitrates, the output is considered transparent, meaning human ears cannot distinguish it from the original uncompressed WAV.
Is there a limit on how many files I can convert?
No! There are no daily conversion quotas; a ten-minute processing limit applies to each media job. Since conversion uses your local device resources, you can convert as many files as you want.
