JPG vs PNG vs WEBP vs AVIF — Which Should You Use?
A practical, benchmarks-driven comparison of the four most common image formats used on the web today.
Choosing the right image format is one of the highest-ROI performance decisions you can make. Here's the short version: use WEBP for most photos, PNG for logos and screenshots that need transparency, AVIF when you can afford slower encoding, and JPG only when compatibility with ancient browsers is required.
In our benchmarks, a 1920×1080 hero image was 380 KB as JPG, 210 KB as WEBP at quality 80, and 140 KB as AVIF at quality 60 — all visually identical.
OneClick.pics supports every one of these formats natively. Convert freely, and use the max-KB slider to fine-tune quality.
