JPEG, PNG, or WebP: picking the right image format

JPEG, PNG, or WebP: picking the right image format

The format you save an image in changes both quality and how fast your page loads.

— JPEG: best for photographs. Small files, smooth colors, no transparency.
— PNG: best for logos, screenshots, and anything needing a transparent background. Sharper edges, but bigger files. Don't use PNG for photos, it bloats your page.
— WebP: a newer format that makes both photos and graphics smaller than JPEG or PNG at similar quality. Use it when you can.

The easy path: install an image-optimization plugin that converts uploads to WebP automatically, so you don't choose each time.

In plain words: photos as JPEG or WebP, logos as PNG or WebP, and let a plugin handle conversion.
