Seenalt — AI Alt Text & Image Optimizer

Automatically generate accurate ALT text for images using AI vision technology and optimize images to WebP/AVIF formats.

Erdinc Bulat

Erdo Image Optimizer is a complete Image SEO & Performance Suite for WordPress. Convert images to WebP/AVIF, bulk-fix alt text, sanitize filenames, enable lazy loading, clean up unused media, and run a 6-point SEO audit — all from a single, modern dashboard.
Most image optimization plugins stop at compression. Erdo goes further: every image in your media library receives a professional SEO health score (out of 6 points). You will know exactly which images are hurting your Google rankings and how to fix them, in bulk, in minutes.
<h4>Why Erdo Image Optimizer?</h4>
<ul>
<li>Image SEO Audit (6 Points): Every image gets a score from 0 to 6 based on alt text, filename quality, title, contextual relevance, dimensions, and format. Fix failing criteria with one click — no guesswork.</li>
<li>WebP & AVIF Converter: One-click conversion from JPEG, PNG, GIF, and HEIC/HEIF to WebP or AVIF. Smart Quality mode automatically finds the smallest file size that still looks great.</li>
<li>Bulk Alt Text Generation: Automatically generate descriptive alt text from filenames for every image missing it. Fix hundreds of images in seconds — critical for accessibility and image SEO.</li>
<li>Filename Sanitizer: Transforms messy uploads like <code>IMG_1234 (copy).JPG</code> into SEO-friendly <code>professional-web-design.webp</code> at upload time. Bulk-rename existing images with automatic database reference updates.</li>
<li>Unused Media Cleanup: Scans your entire library to find images that appear nowhere on your site. Free up disk space and stop confusing search crawlers with orphaned files.</li>
<li>Lazy Loading & WebP Serving: Inject <code>loading="lazy"</code> into content images automatically. Serve WebP to compatible browsers via <code>.htaccess</code> rewrite (Apache) or PHP <code><picture></code> fallback (all servers).</li>
<li>Background Queue & WP-CLI: Bulk-convert thousands of images via WP-Cron — close the browser tab and let it run. Full CLI support: <code>wp erdo convert</code>, <code>audit</code>, <code>restore</code>, <code>stats</code>, <code>clean-cache</code>.</li>
<li>BunnyCDN & REST API: Upload converted images directly to BunnyCDN storage. Headless access via <code>/wp-json/erdo/v1/stats</code> and <code>/wp-json/erdo/v1/audit</code> REST endpoints.</li>
</ul>

Erdo Image Optimizer: Compress & Convert to WebP/AVIF (SEO Audit, Alt Text, Lazy Load)


Expected another "compress and done" plugin and got a complete image SEO toolkit instead. The standout for me is the 6-point audit score on every image. It tells you exactly which ones have weak alt text, bad filenames or the wrong format, and you fix them in bulk instead of one at a time. The WebP/AVIF conversion handles HEIC from iPhone photos too, and it keeps your originals with one-click restore, so there's basically no risk in trying it.



What sold me as a developer was the depth under the hood. Full WP-CLI support (wp erdo convert/audit/restore), real REST endpoints, a background queue so big libraries keep converting after you close the tab, and clean i18n. That's an unusual amount of care for a free plugin, and it's clearly built to WordPress standards, proper nonces, capability checks and escaping throughout.



Runs smoothly, does what it promises, and no upsell nagging. Highly recommended, and I'm looking forward to where this one goes.


More than a compressor a real image SEO suite


Not just another compressor - the 6-point SEO audit on every image and bulk alt text generation alone save hours of work. WebP/AVIF conversion with automatic original backup makes experimenting risk-free, and the WP-CLI commands and REST API endpoints show this was built by a developer for developers. Highly recommended.


Finally an image plugin that takes SEO seriously

Compress & convert images to WebP/AVIF. SEO-audit every image, bulk-fix alt text, filenames & unused media. Lazy loading & BunnyCDN.
