When Should You Convert JPG to PNG?

You need transparency support

Placing logos, product cutouts, or icons over colored backgrounds requires PNG to prevent an opaque white rectangular background.

You plan repeated edits & re-saves

JPEG degrades quality cumulatively with each save. PNG preserves full pixel integrity without generational loss.

Your graphics have sharp text & line art

JPG creates noticeable compression halos around sharp edges and typography. PNG renders every stroke with pixel-perfect clarity.

Keep JPG when file size is priority

PNG files are significantly larger. For web galleries, blog hero banners, and social posts, keep photos in JPG or WebP.
