What changes
AVI files normally carry MP3 audio, which MP3 accepts as they are, so the converter copies the audio untouched: in seconds and with no loss. If not, or if you change the quality, volume or trim, the audio is decoded and compressed again, and loses a little more detail.
If it’s copied, the MP3 is the same size as the AVI's audio track: far smaller than the original, since the picture is gone. If it’s re-encoded, it gets smaller: MP3 stores the same content in less space.
How big the MP3 will be
At 192 kbps, 4 min of MP3 take 5.8 MB.
When it’s worth it
Choose MP3 for: Music, podcasts, and everyday sharing. Small files that play on almost anything.
Stay with AVI for: Legacy Windows video files.

Questions
Does converting AVI to MP3 lose quality?
Usually not. With the default settings the tracks are copied without re-encoding. Quality only drops if you change the quality, size or trim, or if the file uses a codec MP3 doesn’t accept.
What is the MP3 format?
A lossy codec where the audio is cut down by removing sounds the ear can’t hear, so a track keeps a reasonable size at a typical bitrate. It’s still the most widely playable audio format, which is why it’s the default for sharing music.
What is the AVI format?
Audio Video Interleaved, Microsoft's video container from the nineties and still one of the most common files around. It’s a simple wrapper, so whatever codec is inside can be old and heavy, and it was never designed for streaming.
Are the files uploaded?
No. The file is opened in this tab, converted here and saved from here. There’s no account and no watermark.
How many files can be converted at once?
Up to 200 per batch and about 2 GB per file, within the memory this device has available.
