JPG vs PNG vs WebP: which format should you choose?
A practical guide to image quality, transparency and file size.
Choose JPEG for photographs
JPEG is widely supported and uses lossy compression. Lower quality discards detail to save bytes. It works well for photographs with many colors, but repeated editing and saving can create visible artifacts. JPEG cannot store transparency; choose a fill color when converting transparent images.
Choose PNG for sharp edges and transparency
PNG preserves image data without lossy quality reduction and supports transparency. It is useful for screenshots, diagrams and interface graphics. Photographs can be much larger in PNG. A browser PNG encoder does not offer the same quality slider as a JPEG encoder.
Choose WebP for web delivery
WebP supports transparency and can make photographic images smaller. The best format depends on the actual image and encoder, so compare the downloaded result. Check compatibility with the destination app or form before converting.
