What this does
Decodes the sound and encodes it in the new format. Tags such as artist and title, cover pictures and recording-device details are not carried over.
What it can’t do
Restore quality. Converting an MP3 to WAV makes a larger file, not a better one.
A worked example
A voice memo saved as M4A will not attach in an older system that expects MP3. Converted at 128 kbps, it plays there.
Questions
- Which format should I choose?
- MP3 plays on everything. WAV and FLAC keep every detail and suit editing or archiving; FLAC is about half the size. OGG is small and good, but not every device plays it.
- What quality should I pick for MP3?
- 192 kbps is fine for music and more than enough for speech. 320 kbps is the highest MP3 allows.
- Can I convert a video's sound?
- Yes. Add a video and you get its sound in the format you choose.
Your file stays on this device
The tool above runs in a sealed frame that cannot send your file anywhere. It works with airplane mode on, and the counter above it stays at 0. Here is how you can check that yourself.
