Suppose the cover resolution is 800 × 800, the size is 500kb. I want to change it to keep the resolution unchanged and reduce the quality. Use adjust cover, fill in 800 with max size, and lower the quality. There is no response after confirmation.
Suggestion: when using adjust cover, you can customize the max quality and adjust the cover quality, such as no more than 200KB, while the resolution remains unchanged.
Mp3 tag is very easy to use. I hope it will be better and better.
