Note: The lower the threshold number, the more intense the sharpening effect.  Convert images to WebP: WebP is an image format that makes images on the web smaller by 25-35%. Enable or disable the toggle according to your preference. We recommend keeping the toggle enabled, as disabling it may affect your site's loading time.
    
Enabled: (Recommended) Images are converted to a WebP format. Disabled: Images display in their original file format. This may affect site loading time.   Automatically resize images: Wix automatically resizes gallery images to optimize media loading time and maintain site visitor's viewing experience. Click the drop-down to choose when images are resized. We recommend keeping the setting set to Always so that your site's loading time is not affected.
    
Always (recommended): Gallery images are automatically resized to improve your site's loading time. Gallery Only: Only media in the main view of the Pro Gallery are resized. Images in the Expand Mode display in their original resolution. Never: Media load in their original resolution. This may affect your site's loading time, but also allows for better pinch zoom / zoom in with the magnifying glass in the Expand mode.  FAQsClick a question below to learn more about setting the image quality for gallery images:What is the recommended resolution to upload my image in?We recommend you upload the best possible quality media files to your gallery to ensure the best results. Make sure to upload images / videos of at least 2560 X 1440 pixels in resolution. We optimize them to the exact dimensions displayed on screen, without any loss of quality.Does sharpening my image affect the contrast of the whole image?No. Sharpening your image does not affect the contrast of the whole image. The sharpening tool only increases the contrast of the edges of lines within the image. The brighter sides of edges become brighter while the darker sides become darker. 

Note: If you use a very low sharpening threshold, the algorithm may recognize image noise as edges or borders. This can make the image noise more noticeable since the contrast of the noise is increased. What can I do if my images look over-saturated?If your images look over-saturated or too contrasted, try decreasing the values in the Sharpening section.Note:By default, browsers automatically apply aliasing to images to prevent distortion. This is to reduce visual artifacts and other glitches that can result from images displayed in their original quality. A browser's down-scaling algorithm may lead to data loss in high-resolution images. As a result, rendering full-resolution images smaller than the image's actual size affects image quality. This generally results in a smoothening of colors or blurring of the image on your live site in comparison to the original file.
