Zoom Score

How zoom-friendly is any webpage? Paste a URL — we check the source image resolution, hi-res variants, and detail density. In 10 seconds.

We fetch the page once and score it. We don’t store your identity. Cached results are anonymous and expire in 30 days. Some marketplaces (Etsy, Amazon) may block our fetch — if so, try a direct image URL.

How it works

  1. Source resolution (40 pts) — biggest native image we can reach on the page.
  2. Hi-res variants (20 pts) — does the site expose larger crops via srcset or CDN params?
  3. Image count (15 pts) — how many distinct product-worthy images are discoverable.
  4. Pixel density (15 pts) — pixels per byte — a proxy for compression quality.
  5. Lazy-load hygiene (10 pts) — modern formats (WebP/AVIF) and proper loading hints.
