Fluximage can rename your image files automatically based on what the image actually shows. Instead of keeping the camera-generated filename your device assigns, you get a clean, lowercase hyphenated slug that search engines can read and index.

How it works

When you enable SEO rename, Fluximage sends each compressed image to GPT-4o mini (OpenAI Vision). The model reads the image and generates a filename that describes the content — using any keywords or context you provide to match your product terminology. The output filename follows these rules:
  • Lowercase letters and hyphens only (e.g. red-nike-running-shoes)
  • Maximum 50 characters, not including the file extension
  • No special characters or spaces
  • Extension is added automatically based on the output format you chose

Providing keywords and context

The same keywords and context fields used for alt text also influence the SEO rename output. If you fill them in, the generated filename is more likely to include terms relevant to your product catalog or site.
  • Keywords — terms to incorporate (e.g. nike running shoes men)
  • Context — describe your site or product category (e.g. sportswear ecommerce store)

Language

You can select a language for the output filename. The slug is generated in that language, which is useful if your site URL structure is in a language other than English.

Plan requirement

SEO rename requires a Starter plan or higher. It is not available on the free plan.
Each image processed with SEO rename enabled uses 1 AI credit. If you also enable AI alt text for the same batch, both features together still count as 1 credit per image — not 2.
