JPG vs PNG vs WebP vs AVIF: Which Image Format Should You Choose?

Quick answer

Use JPG for photos, PNG for transparency and sharp graphics, WebP for web optimization, and AVIF when you want stronger compression and modern compatibility is acceptable.

JPG

JPG is widely supported and ideal for photos. It creates relatively small files, but it uses lossy compression and does not support transparency.

PNG

PNG is useful for screenshots, logos, icons, line art, QR codes, and transparent backgrounds. It preserves sharp edges well but can create large files, especially for photos.

WebP

WebP supports good compression and transparency. It is a strong choice for websites because it can reduce loading time while keeping quality acceptable.

AVIF

AVIF can provide excellent compression, but compatibility and processing speed should be considered. It is useful for modern web performance optimization, not always for general file exchange.

Summary

Choose image formats by use case. Photos, transparency, website performance, and compatibility all lead to different choices.
