How do I compress an image? (Old Editor)
You can compress images in almost any photo program, such as Adobe Photoshop. Simply save as Internet web size. It is recommended to save your images at the size you want it them to be displayed.
In addition, make sure your image is in RGB color mode and not CMY. To check this in Adobe Photoshop: Click the image > click Image Mode. This will ensure that your image is displayed in the best quality possible once uploaded to your Wix site.
Wix optimizes your images automatically for both site loading time and image quality. Therefore, provided that your image is less than 15mb, we do not recommend compressing it externally.
