PNG vs JPG

Use JPG for photographs and PNG for everything with sharp edges: screenshots, logos, diagrams and text. PNG never loses detail but makes photos several times larger; JPG keeps photos small but smudges lines and can’t be transparent.

Watch out with PNG

Photographs saved as PNG balloon in size. A holiday photo that is 3 MB as JPG can be 15 MB as PNG, because lossless compression can do very little with the fine grain of a real photograph.

Watch out with JPG

Re-saving a JPG again and again degrades it, because each save compresses the already compressed version. Keep an original and export to JPG once, at the end.
