Questions about Compress Images
How do I reduce the file size of a photo on Mac?
Drop the photo into Compress Images and click Compress. Medium is a good balance of size and quality; Low gives the smallest files for sharing and the web.
Will compressed photos look worse?
High is meant to look the same as the original with smaller savings. Low trades some detail for much smaller files.
Is HEIC smaller than JPEG?
Usually, at similar quality. Choose HEIC as the format if the photos will be viewed on Apple devices; choose JPEG if they need to open everywhere.
