How to choose the right format: JPEG vs PNG vs WebP vs AVIF

A practical guide to picking the best image format for photos, graphics, and transparency.

format comparison

Choosing the right format depends on the content: use JPEG or WebP for photos, PNG for graphics or transparency, and AVIF or WebP for the best compression when supported. For photos, WebP typically reduces size 25–35% vs JPEG at similar quality. For logos or UI assets, PNG or lossless WebP keeps sharp edges. For transparent photos, compare PNG vs WebP (lossless) to keep quality with smaller size.

When to use each format

  • Photos: WebP (or JPEG when compatibility is required)
  • Graphics/Logos: PNG or lossless WebP (preserve edges)
  • High efficiency: AVIF/WebP when supported

Quick decision guide

  • Need transparency? Prefer PNG or lossless WebP
  • Max savings for photos? Choose WebP or AVIF
  • Legacy compatibility? Use JPEG
