Frequently Asked Questions
Common questions about Cimo – Free Instant Image Optimizer & WebP Converter
Unlike server-side plugins, Cimo processes everything in your browser. No external APIs, no server processing, no waiting - just instant optimization as you upload.
When you upload an image into your Media Manager (let's say a .jpg), you'll notice that after uploading, it will be a .webp image! You will also find some additional information in the Media Manager about your uploaded image.
Cimo works in all modern browsers including Chrome, Firefox, Edge, and Opera. This currently does not work with Safari, please use one of the browsers mentioned. If you use Safari, the image will just upload as it normally would.
Yes! Unlike other plugins that charge per image or have monthly quotas, Cimo's image optimization and compression is completely unlimited and free forever.
No! Cimo processes everything locally in your browser. Your media assets never leave your device until they're uploaded to your WordPress site, nor do they go to another server for processing.
Our browsers right now are quite powerful and already have the capabilities for converting images to different formats. At the very core, the conversion is done via a clever use of JavaScript's Canvas API to process your images in the browser right before they're uploaded to WordPress. This means faster uploads, no server load, and complete privacy.
Currently WebP conversion is fully supported.
Currently, Cimo optimizes images during the upload process. For existing images, you can re-upload them to get the optimization benefits.
Yes Cimo can convert video and audio files, but that's in our premium version, check out website for more information on it.
Actually, it speeds them up! Since images are compressed before upload, they transfer faster and take up less storage space.
