Capabilities

What WPStories Image Optimizer Can Do

Discover the powerful features and capabilities

Automatic Image Conversion

Every image uploaded to your Media Library is automatically converted to your chosen format — WebP or AVIF. This includes featured images, gallery uploads, WooCommerce product images, and all auto-generated thumbnails.

  • Convert on upload — no manual steps required
  • Supports JPG, PNG, GIF, BMP, and TIFF input formats
  • Processes all WordPress thumbnails automatically
  • Configurable quality settings per format
  • Max dimension resizing to control output size

Bulk Optimization

Have thousands of existing images? The built-in bulk optimizer converts your entire uploads directory in one click. Progress tracking shows you exactly how many images have been processed and how much space you have saved.

Performance & SEO Benefits

Smaller images mean faster page loads. Google uses Core Web Vitals — especially Largest Contentful Paint (LCP) — as a ranking factor. By reducing image file sizes by 25-50%, this plugin directly improves your site speed and SEO performance.

  • WebP images are 25-35% smaller than JPEG with similar quality
  • AVIF images are 50% smaller than JPEG with better quality
  • Faster page loads improve bounce rate and user engagement
  • Works with all modern browsers (Chrome, Firefox, Edge, Safari)

Privacy & Server Friendly

Everything runs on your own server — no external APIs, no third-party services, no data leaving your site. The plugin uses PHP's built-in GD Library or Imagick extension, so it works on virtually any WordPress hosting environment.

  • No external API calls — 100% server-side processing
  • No data sent to third-party services
  • Works with shared hosting, VPS, and dedicated servers
  • Compatible with WordPress 6.0+ and PHP 7.4+

Frequently Asked Questions

What image formats can be converted?

JPG, PNG, GIF, BMP, and TIFF images can all be converted to WebP or AVIF.

Do I need Imagick installed on my server?

No. The plugin works with GD Library as a built-in fallback. However, Imagick is recommended for faster processing and better image quality.

Will this slow down my uploads?

For most images, the conversion adds less than 1 second to the upload time. The process runs in the background during the normal upload flow.

Can I keep the original files?

Yes. There is an option in the settings to keep the original JPG/PNG files alongside the converted WebP/AVIF versions.

Does this affect my SEO?

Yes — positively! Smaller images mean faster page loads, which improves Core Web Vitals scores. Google uses these metrics as a ranking factor, so this plugin directly helps your SEO.

What happens if my server doesn't support WebP or AVIF?

The plugin will display a warning in the admin area. You can switch to a supported format in the settings, or contact your hosting provider to enable the required PHP extension.

Can I bulk optimize my existing images?

Yes. The plugin includes a bulk optimize tool that converts all existing images in your uploads directory. Progress tracking shows how many images have been processed and how much space has been saved.

Is this plugin really free?

Yes, 100% free. There are no premium tiers, no hidden costs, and no upsells. It is released under the GPLv2 license.
