- Any embedded previews, thumbnails, or artwork found inside the M4A container
M4A metadata FAQs
What can I see in a M4A file?
Inspect iTunes-style tags (artist/album/title, track/disc numbers), artwork, gapless flags, loudness hints, and bitrate/sample rate/channels without altering M4A files.
Do you change or recompress my M4A file?
No. The viewer only reads metadata from your M4A file and shows it back—streams, pixels, and content stay untouched.
What if my M4A file has little or no metadata?
Some M4A files ship with minimal fields. We show everything present—if a tag is missing (like GPS or author), there simply isn't any data to display.
Can I verify attachments or previews in a M4A?
Yes. If the M4A contains embedded previews, cover art, fonts, or thumbnails, we surface those entries so you know what ships with the file.
Can I copy the M4A metadata for documentation?
You can copy the on-screen results to include in tickets, audits, or delivery notes without modifying the original M4A.
