Use PNG for logos, interface graphics, screenshots with text, and images requiring transparency. Use JPG for photographs and large continuous-tone images when smaller files matter more than perfect pixel preservation.
Häufig gestellte Fragen
Why is PNG larger than JPG for photos?
PNG preserves pixels losslessly, while JPG discards subtle detail to reduce file size.
Which format is better for screenshots?
PNG is usually better for sharp text and interface edges, although WebP can also work well.
Can JPG have a transparent background?
No. Choose PNG or WebP when transparency is required.
