What changes
Both formats are lossy. Converting decodes the file and compresses it again, so it loses a little more detail on top of what the original had already lost: the result is slightly worse than the file you started with.
The file 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

Questions
Does converting M4V to MP3 lose quality?
A little. Both formats are lossy, so the file is compressed again and loses a bit more detail.
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 M4V format?
An MP4 container holding MPEG-4 Simple Profile video, which is what Apple devices record by default. The file is essentially an MP4 with another extension, and how it plays can differ between Apple devices and Android phones.
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.
