How to Resize Images for Websites
Choose practical image dimensions, preserve aspect ratio, and avoid blurry or distorted website graphics.
Step-by-step instructions
1. Choose the display size
Determine how large the image will appear in the layout, including high-density screens where relevant.
2. Preserve proportions
Keep the aspect ratio locked unless you intentionally need a crop. Stretching width and height independently distorts images.
3. Export and test
Save the resized image and inspect it on mobile and desktop. Compare visual quality and file size before publishing.

Does making an image larger improve quality?
No. Upscaling does not restore detail missing from the original image.
Should all website images use the same dimensions?
No. Match dimensions and aspect ratios to each component and use responsive images when practical.
