How can I convert an album that is FLAC (high quality lossless) into an MP4 specifically without losing quality or is it even possible? (sopuli.xyz)

I have an album thats a bit more than 200MB, converted to just an audio only M4a or MP4 its still under 80MB

Is that 120+MB all chaff or is there another way to prevent losing all muh damn wheat

CONSTRAINT/NON-CONSTRAINTS

FILE SIZE DOES NOT MATTER AT ALL TO ME. JUST TO BE CLEAR

MUST BE AN MP4 "video" file. I get that MP4 is a container or whatever but that is a hard constraint—Please respect that

M4A/AAC are not acceptable. It must be within the container that is MP4, non-negotiable

Flac has all the sounds a computer can detect. "Lossy" formats (like AAC typically used in mp4 containers) strive to only retain the sounds a person can detect.

Unless you're a particularly astute listener AND are listening on high end gear you are unlikely to care about the difference in sound quality.

It might matter if you're going to do further conversions, though. If you want to convert the album to 2-3 lossy formats it's best to start with something lossless. But that's a pretty niche use case in 2025.
