JPG vs PNG vs WebP: Which Image Format Should You Use?
2026-06-22
Three formats cover almost every everyday image: JPG, PNG and WebP. Choosing the wrong one means bloated files or lost quality. The good news is the decision is simple once you know what each format is built for.
JPG — for photographs
JPG (or JPEG) uses lossy compression tuned for photographs: skies, skin, scenery, anything with smooth gradients. It throws away detail your eye won't miss and produces small files. The trade-off: it can't store transparency, and it gets blocky on sharp edges and text. Use JPG for camera photos and any richly colored image where small size matters.
PNG — for graphics and transparency
PNG is lossless: it reproduces every pixel exactly, and it supports transparency. That makes it perfect for logos, icons, screenshots, line art and anything with crisp edges or flat color. The cost is size — a PNG photo can be many times larger than the JPG equivalent. Rule of thumb: PNG for graphics, never for photos (unless you truly need lossless). If your PNG is actually a photo, convert it to JPG to shrink it dramatically.
WebP — the modern all-rounder
WebP, from Google, does both jobs: it has a lossy mode (smaller than JPG at the same quality) and a lossless mode with transparency (smaller than PNG). Typical savings are 25–35% over JPG and often more over PNG. Every current browser supports it, so for images that live on a website, WebP is usually the best choice. Convert your existing assets with JPG to WebP or PNG to WebP.
The 10-second decision
Is it for a website? Use WebP. Need transparency or a crisp logo/screenshot? PNG (or lossless WebP). A photo to email or upload to a form? JPG. Whatever you pick, you can compress it further afterwards — all in your browser, nothing uploaded.
