Why Filenames Affect Image SEO
Google's image publishing guidelines state: "The filename can give Google clues about the subject matter of the image. For example, my-new-black-kitten.jpg is better than IMG00023.JPG."
This is not speculation. Google's own documentation confirms filenames are a ranking signal. Every image on your site with a camera-generated filename (IMG_, DSC_, DCIM_, Screenshot_) is a missed ranking opportunity.
Picture Optimizer rewrites filenames based on what the AI sees in the image. The output: lowercase, hyphen-separated, ASCII-only slugs that describe the image content.
