HEIC FAQ
Is HEIC better than JPEG?
Depends on the job. HEIC is apple's default iphone photo format with excellent compression, and typically around half the size of JPEG at similar quality. JPEG still wins when you need guaranteed support everywhere, such as in email clients or legacy software.
Does HEIC support transparent backgrounds?
Yes. HEIC stores an alpha channel, so logos, icons, and cut-out graphics keep their transparent areas intact.
How large is a typical HEIC file?
typically around half the size of JPEG at similar quality. Actual size always depends on image content and quality settings — a detailed photograph and a flat two-color logo in the same format can differ by an order of magnitude.
