The image is decoded, resized, converted, and exported with Canvas APIs on the visitor's device. Hosting cost stays close to a normal static site.

Put this tool on one old domain first and track indexing, crawls, page speed, and backlinks before adding more sites.

Later, add lightweight related pages such as image size guides, format comparisons, converter examples, and SEO image checklists.

The browser performs the heavy work, so a cheap VPS or static host is enough for a long-running pilot.
