Choose media to optimize

Cimo optimizes new images in the browser before they reach the WordPress Media Library. Cimo Premium adds bulk optimization for images, videos, and audio already in the library. Select existing files to process them in one operation without server-side processing.

For new video and audio, processing happens during upload, before the files are added to the Media Library. Options let you downscale video resolution and adjust audio quality. Premium can also automatically optimize images, videos, and audio uploaded through popular form plugins, including Gravity Forms, WPForms, Ninja Forms, Formidable, and Fluent Forms.

Set image behavior

Smart Optimization selects compression settings for each image to reduce manual adjustments. Under Settings > Cimo, you can set WebP quality and maximum image dimensions, control WordPress image scaling, and manage thumbnail generation. The page also shows optimization statistics.

The Recommended preset sets WebP quality to 80%, the maximum image dimension to 1920px, and thumbnail generation to disabled.

Check how images appear

Low Quality Image Placeholders show a subtle placeholder for images in native image blocks while the full image loads, then fade in the loaded image. Stealth Mode hides Cimo branding and interface elements while its optimization functions continue to work.

Use Cimo with your editor

Cimo is intended for the native WordPress Block Editor and works with integrations with Elementor, Divi, Breakdance, Bricks Builder, Oxygen, Beaver Builder, WPBakery, Stackable, Spectra, Kadence, Greenshift, GenerateBlocks, and WooCommerce. Divi support is partial: dropping files is not supported.

Install and configure

1. Install and activate Cimo Premium in WordPress.
2. Open Settings > Cimo and review image, thumbnail, and scaling settings.
3. Apply the Recommended preset or configure the settings manually.
4. Upload new media as usual, or select existing files in the Media Library for bulk optimization.
5. Use form-extension processing, video and audio options, placeholders, or Stealth Mode as needed.

Cimo works in modern Chrome, Firefox, Edge, and Opera browsers. In Safari, images are optimized but keep their original format; WebP conversion is not supported.
