Find image issues before they slow down your website
Images are often the heaviest part of a webpage. Large JPGs, oversized PNG files, missing dimensions, and weak alt text can hurt page speed, accessibility, and search performance. PicFlow AI's Website Image Scanner gives you a quick audit of public page images so you can see which files are worth compressing, resizing, converting, or improving before publishing.
The scanner is especially useful for bloggers, ecommerce stores, landing pages, portfolios, agencies, and developers preparing pages for better Core Web Vitals. After scanning a page, continue with the image compressor, image converter, image resizer, or image SEO analyzer.
What the scan results mean
PicFlow estimates total known image weight, potential savings, missing alt text, missing width and height attributes, and format opportunities such as converting JPG or PNG files to WebP. These checks are practical signals rather than a full Lighthouse audit, but they are enough to identify common image problems quickly.
