Cimo

Optimize all your images instantly and for free.

Cimo optimizes, resizes, and converts your images to WebP instantly as you upload them — right in your browser, before the files are ever added to your Media Library. From WordPress’ point of view, it’s as if the image was already optimized before you uploaded it, keeping your site’s load speed fast without compromising quality.

Visit Cimo’s website to learn more about how Cimo does things.

• Unlimited usage – upload as many images as you want
• Instant optimization – virtually no waiting time
• No extra server load, bandwidth, or external image-processing services

Note: Cimo works in all modern browsers (Chrome, Firefox, Edge, Opera). In Safari, images will be optimized but will keep their original file format. WebP conversion is not supported in Safari.

Image Optimization options:

• WebP quality – set the quality level for WebP conversion (1-100), defaults at 80%
• Max image dimension – automatically resize images to a maximum dimension while preserving aspect ratio
• WordPress automatic scaling – disable WordPress’s built-in 2560px image scaling
• Thumbnail generation – disable all WordPress thumbnail generation to save disk space
• Individual thumbnail sizes – selectively enable/disable specific thumbnail sizes
• Preset configurations – one-click “Recommended” settings for optimal performance
• Statistics dashboard – view total storage saved, compression ratio, and optimization metrics
