Compress Images for a Faster Website (Without the Blurry Mess)
Images are the heaviest part of most web pages. Oversized hero photos are the #1 reason a site fails Core Web Vitals. Here is a practical workflow: resize first, then compress, then pick a modern format.
Resize before you compress
A 4000-pixel photo displayed in an 800-pixel slot wastes roughly 96% of its pixels. Resizing to the real display size (or 2× for retina screens) is the single biggest saving, before compression even starts.
Find the quality sweet spot
For JPG and WebP, quality 75–85 is the sweet spot for photographs: file size drops sharply while artefacts stay invisible at normal viewing distance. Go lower only for thumbnails. Compare the before/after size and preview — a good compressor shows you both.
Measure the result
Aim for under 200 KB for hero images and under 75 KB for inline content images. If a page still feels slow after compression, the problem is usually the number of images, not their size — lazy-load anything below the fold.
