How to compress a M4A file

- 3 Drop your M4A files, then download them lighter.
How Morfile makes your M4A files lighter
Morfile re-encodes the sound at a lower bitrate, chosen to reach the size you want.
Aim for an exact size
In the app, choose a target size: under 1, 2, 5, 10 or 25 MB, or any value you like. Morfile finds the best quality that fits, and tells you clearly if it can’t be done.
Frequently asked questions
Is it free to compress a M4A file?
M4A compression is part of Morfile Pro: 24-hour pass for €3.99 or lifetime access for €24.99, no automatic renewal. JPG, PNG, WebP and PDF compress for free.
Is my M4A file uploaded to a server?
No. Compression happens in your browser, on your device. Even a big video is processed with no upload time.
Will I lose quality?
Light compression is invisible. Strong makes the file as light as possible, with a loss you can see up close. For images, a slider compares before and after.
How do I get under an email size limit?
In the app, choose the “under 25 MB” target size (Gmail, Outlook) or “under 10 MB” for stricter mail services. Morfile does the rest.
