Frequently asked questions
What's the difference between WAV and MP3?
WAV is uncompressed and lossless, so files are large. MP3 uses lossy compression; the same recording is usually 5–10 times smaller.
Which quality should I choose?
192–256 kbps is enough for music and 128 kbps for speech. 320 kbps is the highest MP3 quality.
How many files can I convert at once?
There is no fixed limit; files are processed one after another. Download the finished ones as a single ZIP.
Are my files safe?
Yes. The conversion happens entirely in your browser; your files are never sent to a server.
