Large images slow down websites and fill up storage. The good news: you can usually cut 60โ90% of an image's size with almost no visible difference. Here's how.
WebP is the sweet spot in 2026 โ typically 25โ35% smaller than JPEG at the same quality, with wide browser support. Use JPEG for maximum compatibility, and reserve PNG for graphics that need transparency.
Quality is the biggest lever. At 70โ80% most photos look identical to the original but weigh a fraction. Below 60% you may start to see artifacts in fine detail.
If your image is 6000px wide but displayed at 1200px, resize it first. Capping the longest side at 1920px (or 1280px for the web) massively reduces size on top of compression.
