What image size is best for WordPress?

For most content images, keeping files around 100–200KB (and width no larger than needed) loads fast while still looking sharp on screen.

Do I still need an optimization plugin?

Compressing before upload reduces the need for one and keeps your media library small from the start. Converting to WebP shrinks files even further.

Oversized images are the number-one cause of slow WordPress sites — and page speed affects both bounce rate and SEO. Compressing each photo to a lean web-ready size before you upload keeps your media library light and your pages fast, without a plugin.

It all runs in your browser, so nothing is uploaded to a third-party optimizer.
