Resize an Image for WordPress
Faster WordPress pages start before upload: resize to display size, compress, and use WebP, better speed and SEO.
Uploading full-resolution photos is the top cause of slow WordPress sites. Resize each image to the width it actually displays at (usually 1200–2048px), compress it, and convert to WebP for the smallest size. A featured image of 1200×628px works well. Our Resize, Compress and WebP tools do it in your browser.
| Content image width | 1200–2048 px (match your theme) |
|---|---|
| Featured image | 1200 × 628 px (also used for sharing) |
| Best format | WebP (smaller than JPG/PNG at same quality) |
| Target file size | Under ~150 KB where possible |

How to do it
- 1
Resize to the display width
Set the width to what your theme actually shows (often 1200–2048px), uploading a 6000px phone photo just slows the page.
- 2
Compress the image
Run Image Compressor so each image is light without visible quality loss.
- 3
Convert to WebP
WebP is markedly smaller than JPG/PNG at the same quality and is supported everywhere modern.
- 4
Upload the optimized file
Add the resized, compressed WebP to your media library, pages load faster and Core Web Vitals improve.
- Image weight is usually the biggest slowdown on WordPress, fixing it improves Core Web Vitals and SEO.
- Resize before upload. Relying only on the theme to scale still ships the giant original to visitors.
- The featured image (1200×628) doubles as the social share image via Open Graph.
