Different situations call for different image formats. A logo needs PNG for transparency. A photo needs JPG or WebP for small file size. A modern website should use AVIF for best compression.
When to Use Each Format
JPG
Universal photo format. Lossy compression, no transparency. Every device supports it.
Best for: Photos, social media, email attachments, maximum compatibility.
PNG
Lossless, supports full transparency. Larger files but perfect quality.
Best for: Logos, icons, screenshots, graphics with text, transparent backgrounds.
WebP
Google's modern format. 25-30% smaller than JPG, supports transparency.
Best for: Web images — the default recommendation for most web use cases.
AVIF
Newest format. 50% smaller than JPG, supports transparency and HDR. Growing browser support.
Best for: Maximum compression. Future-proofing your website.
