SEOPix optimizes your WordPress images for SEO in one click. When you upload an image, AI analyzes it and:
<ul>
<li>Compresses — up to 90% smaller without quality loss</li>
<li>Renames — generates SEO-friendly filenames based on image content (e.g. IMG_4523.jpg → vintage-leather-bag.webp)</li>
<li>Generates alt-text — descriptive, keyword-rich alt-text in 7 languages</li>
<li>Converts format — WebP, JPEG, or PNG</li>
</ul>
Works automatically on upload or manually from the Media Library. Supports bulk optimization.
<h4>Features</h4>
<ul>
<li>Auto-optimize on upload (can be toggled off)</li>

<li>Platform presets: Web, Shopify, Etsy, Amazon, Instagram</li>
<li>Alt-text in 7 languages: EN, FR, ES, DE, IT, PT, NL</li>

<li>No server-side processing — uses seopix.co API</li>
</ul>
<h4>How It Works</h4>
<ol>

<h4>Pricing</h4>

<li>Subscriptions: from $4.99/month (100 images/month, credits accumulate)</li>
</ul>
<h3>External services</h3>
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:
<ul>
<li>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 <code>POST</code> request to <code>https://www.seopix.co/api/process-single</code> containing: the image file binary, your SEOPix API token (as a Bearer token in the <code>Authorization</code> 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 <code>source</code> field set to <code>"WordPress plugin"</code> so SEOPix can track plugin usage.</li>
<li>When the Media Library, Settings page, or WordPress admin bar loads (and an API token is configured), the plugin sends a <code>GET</code> request to <code>https://www.seopix.co/api/auth/extension</code> with your API token in the <code>Authorization</code> header, in order to retrieve and display your current credit balance.</li>
<li>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 <code>seopix.co</code>). The plugin then fetches that URL with a <code>GET</code> request to download the optimized image and replace the original in your Media Library. No additional user data is sent in this download request.</li>
</ul>
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:

SEOPix — AI Image SEO Optimizer

Automatically compress, rename with SEO keywords, and generate alt-text for your images using AI.

Bogdan Bendziukov

Looking for a WordPress image optimizer without an API key? Squeeze is a local WebP converter that lets you compress images in WordPress, convert uploads to WebP, and bulk compress your media library without ShortPixel-, Imagify-, or Smush-style monthly caps. Processing runs in your admin browser—unlimited squeezes, full privacy, and no uploads to third-party compression servers.
If you need a webp converter wordpress plugin, a shortpixel alternative without recurring API fees, or an image optimizer without api keys, Squeeze keeps optimization on your server and in your browser instead of a SaaS queue.
Unlike cloud-based plugins, Squeeze:
♾️ No compression limits — squeeze your entire Media Library, not just the first 100–500 images per month. 
☁️ No third-party servers — images never leave your site; processing happens locally in the browser (ideal for GDPR-sensitive and membership sites). 
⚡ Direct WebP conversion — convert JPG/PNG to WebP and replace the original file on disk (no duplicate copies cluttering storage). 
🖼️ Optimize on upload — compress in Gutenberg, GenerateBlocks, and the Voxel theme before files hit the server (Elementor on-upload squeeze is available in <a href="https://pluginarium.com/squeeze/#premium" rel="nofollow ugc">Premium</a>).
The result: smaller files, faster page loads, and lower hosting storage—without SaaS fees or API keys.
