Start with visible images
Prioritize hero, LCP, and above-the-fold assets before long-tail gallery files. These are the images users wait on first.
Site Image Audit - free
Find the images silently slowing down your site in under a minute.
Paste any public URL. Optimagio statically scans mobile and desktop evidence, finds oversized raster files, missing modern formats, likely LCP candidates, image SEO gaps, caching, and render-blocking signals before using a cloud optimization credit.

ZIP Optimized assets with replacement maps
Turn a site audit into a short implementation plan.
Before any optimization credit is used, the audit shows what to fix first: visible image weight, oversized dimensions, missing modern formats, and manual blockers your team should review.
Resize to rendered dimensions
Use mobile and desktop evidence from the scan to stop shipping full-resolution originals into much smaller layout slots.
Convert safe same-origin files
Generate WebP or AVIF for raster assets you control, while keeping original-format fallback markup for compatibility.
Hand off exact fixes
Send developers the source URL, affected pages, replacement map, and manual blockers like cache headers, dimensions, alt text, or third-party assets.
