Imaxio SEO Image Renamer and Alt Text is a lightweight plugin built for site owners who want better image SEO without manually renaming files or writing alt text for every upload.
It analyzes images added to the WordPress media library and produces descriptive filenames and alt tags meant to reflect what each image actually shows, saving time on a task that is often skipped altogether.
The plugin connects to an AI provider chosen by the site owner: Google Gemini, OpenAI, or Claude. Each image is converted to Base64 and sent to that provider only when the user clicks the AI Image Rename button in the media library, along with a text prompt asking for a structured response.
A site owner needs their own API key from the selected provider, since the plugin does not include one, and results appear directly in the Media Library and Attachment Details modal once processing finishes.

Key Features of Imaxio SEO Image Renamer and Alt Text
Bring your own AI provider. Site owners connect their own API key for Google Gemini, OpenAI, or Claude, choosing whichever provider they prefer. There is no intermediary service between the site and the AI provider.
Project scope for context. A global Project Scope field lets the site owner describe their niche or audience, such as a specific type of online store. The AI uses this description so generated filenames and alt text stay relevant to the site’s actual content.
One-click renaming. Clicking the AI Image Rename button in the media library triggers the process without extra confirmation steps. The physical file is renamed right away, removing the friction of manual editing.
Automatic model selection. The plugin detects and selects fast, cost-efficient models from the chosen provider, such as lighter versions of GPT, Gemini, or Claude. This keeps processing quick without requiring the site owner to pick a specific model.
Duplicate filename protection. Before renaming a file, the plugin checks whether a file with the generated name already exists. If it does, a timestamp is appended so existing files are never overwritten.
Live updates without reloading. Once an image is processed, its new title, alt text, filename, and file URL update immediately in the Media Library and Attachment Details view. No page refresh is needed to see the results.

Good to Know About Imaxio SEO Image Renamer and Alt Text
The plugin is free and open-source, though each AI provider may charge for the images it processes, typically small amounts per image. The developer notes that renaming only affects the main physical file, not existing thumbnails, so it works best on images renamed right after upload and before insertion into a post.
If an image has already been embedded in published content, renaming it afterward may break that image’s link in the post. The developer also notes that Gemini users on servers located in the EU may encounter a quota error unless they link a billing account in Google AI Studio.
