How to resize images for a website
Website images should match their rendered aspect ratio and should not be dramatically larger than necessary. Correct dimensions reduce transfer size, improve layout stability, and help pages display consistently across templates.
WebP is efficient for many modern sites. JPG remains useful for photographs and broad compatibility. PNG is best reserved for transparency, screenshots, and graphics that need lossless edges. Keep original source files and let your CMS generate additional responsive sizes when supported.
Frequently asked questions
What size should website images be?
The correct size depends on the rendered container. Common starting points include 1200 x 630 for social previews and 1600 x 900 for article heroes.
Should I use WebP, JPG, or PNG?
Use WebP for efficient modern delivery, JPG for compatible photographs, and PNG for transparency or sharp graphics.
Does resizing improve website speed?
Reducing oversized pixel dimensions usually lowers download size and decoding work, which can improve performance.
Are images sent to a server?
No. Resizing and export happen locally in your browser.
