Web pages
Use WebP or AVIF
Both are supported by all modern browsers. WebP is the safe default. AVIF shaves off another 10–15% if your audience is on recent browsers.
Photos to share
Use JPEG
JPEG is universally understood by every device, messaging app and email client. Keep quality between 75–85 to balance file size and sharpness.
Logos and icons
Use PNG
PNG supports full transparency with no quality loss, making it the right choice for graphics that sit on coloured or patterned backgrounds.
