原文外掛簡介
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

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 POST request to https://www.seopix.co/api/process-single containing: the image file binary, your SEOPix API token (as a Bearer token in the Authorization header), 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 a source field 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 GET request to https://www.seopix.co/api/auth/extension with your API token in the Authorization header, 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 a GET request 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:
