Description
SEOPix optimizes your WordPress images for SEO in one click. When you upload an image, AI analyzes it and:
- Compresses — up to 90% smaller without quality loss
- Renames — generates SEO-friendly filenames based on image content (e.g. IMG_4523.jpg vintage-leather-bag.webp)
- Generates alt-text — descriptive, keyword-rich alt-text in 7 languages
- Converts format — WebP, JPEG, or PNG
Works automatically on upload or manually from the Media Library. Supports bulk optimization.
Features
- Auto-optimize on upload (can be toggled off)
- Manual “Optimize” button in Media Library
- Bulk optimize selected images
- Platform presets: Web, Shopify, Etsy, Amazon, Instagram
- Alt-text in 7 languages: EN, FR, ES, DE, IT, PT, NL
- Shows compression savings per image
- No server-side processing — uses seopix.co API
How It Works
- Install the plugin
- Get a free API token at seopix.co
- Enter the token in Settings SEOPix
- Upload images — they’re automatically optimized
Pricing
The plugin is free. Image processing uses credits from your seopix.co account:
- Free: 15 credits/month (1 credit = 1 image)
- Credit packs: from $14.99 (500 images, never expire)
- Subscriptions: from $4.99/month (100 images/month, credits accumulate)
External services
This plugin relies on the SEOPix API (seopix.co) to process images. Without this service the plugin cannot compress images, generate SEO filenames, or produce alt-text — all image analysis and AI processing happens on SEOPix servers, not on your WordPress site.
SEOPix API — https://www.seopix.co/api
What it is used for: compressing images, generating SEO-optimized filenames from image content using AI, generating multilingual alt-text using AI, and checking the remaining credit balance on your SEOPix account.
What data is sent and when:
- When an image is optimized (either automatically on upload, manually via the “Optimize” button in the Media Library, or through the “Optimize with SEOPix” bulk action), the plugin sends a
POSTrequest tohttps://www.seopix.co/api/process-singlecontaining: the image file binary, your SEOPix API token (as a Bearer token in theAuthorizationheader), and the optimization options you configured in Settings SEOPix (platform preset, output format, alt-text language, filename language, and optional max width/height). The request also includes asourcefield set to"WordPress plugin"so SEOPix can track plugin usage. - When the Media Library, Settings page, or WordPress admin bar loads (and an API token is configured), the plugin sends a
GETrequest tohttps://www.seopix.co/api/auth/extensionwith your API token in theAuthorizationheader, in order to retrieve and display your current credit balance. - After an image is processed, the SEOPix API returns a temporary signed URL pointing to the optimized image stored on SEOPix’s own CDN (hosted on
seopix.co). The plugin then fetches that URL with aGETrequest to download the optimized image and replace the original in your Media Library. No additional user data is sent in this download request.
No personal information about site visitors, site administrators, post content, or any data other than what is listed above is ever transmitted. The plugin never contacts any other third-party service.
This service is provided by SEOPix (operator of seopix.co). By using the plugin you agree to the SEOPix terms and privacy policy:

Changelog
1.0.4
