(AVIF / WebP / fallback) and CSS background-image URLs. The SEO Audit tab's
image count is different by design: it counts logical <img> elements.
SVGs are skipped because they're vector; re-encoding them as raster would lose quality.
Why Optimise Your Images?
Images account for the majority of a typical web page’s total weight. Unoptimised images slow down page loads, hurt search engine rankings and increase bandwidth costs. By choosing the right format, quality level and dimensions you can often reduce file sizes by 60–95% with no perceptible loss in quality.
This tool goes beyond simple compression. Upload an image or scan an entire web page to get a side-by-side comparison of every modern format at multiple quality levels, so you can make an informed decision about the best trade-off between file size and visual fidelity.
How It Works

- Compare formats: see your image converted to AVIF, WebP, JPEG and PNG at different quality levels
- Pick the winner: the smallest file is highlighted automatically with exact savings shown
- Download: grab individual files or a ZIP bundle with ready-to-use
