Image formats affect file size, transparency, visual quality and compatibility. JPEG, PNG and WebP are common formats for web and everyday graphics, but each has different strengths.
JPEG
JPEG is widely supported and commonly used for photographs. It generally uses lossy compression and does not support transparent pixels. Repeated saving can introduce additional compression artefacts.
PNG
PNG supports lossless compression and transparency. It is useful for logos, icons, screenshots and graphics with sharp edges. Photographs saved as PNG may be larger than comparable JPEG or WebP files.
WebP
WebP supports lossy and lossless compression as well as transparency. It can be efficient for web images. Consider software and device requirements if your images are used outside modern browsers.
Quick selection guide
- Photos: JPEG or WebP is often suitable.
- Transparent logos: PNG or WebP.
- Screen captures with fine text: PNG can preserve crisp edges.
- Modern website imagery: consider WebP and test the final result.
