Why Are My Website Images So Large?

Images are large because the file still contains pixels for print, retina, or lossless UI. The website asked for a picture, not a master. Convert to WebP and cap width; the 'mystery weight' disappears.

Five usual culprits

iPhone HEIC exported as JPEG at full resolution. PNG screenshots. Figma @2×. Plugin-generated 'backup' originals. Designers sending TIFF. All of them become reasonable WebP files in one drop.

Why it matters

  • CMS 'max upload size' is not a quality policy.
  • Themes display at 800 px and still link a 5000 px file.
  • Nobody looks at Network → Img until PageSpeed yells.

How to do it

  1. Sort the media library by size. Convert the top 100.
  2. Set max width to the theme's large size.
  3. Replace. Repeat monthly if many authors upload.

Settings that work

If you do nothing else: 1600 px / 80% on everything raster except logos (SVG).
