No, the image quality isn’t automatically adjusted based on the connection speed of the visitor’s browser.
However, FastPixel resizes images to fit neatly within the placeholder based on the visitor’s viewport. For example, for a 100x100px placeholder, an original image that is 800x800px will be resized to fit properly.
Additionally, images are automatically converted and served based on the visitor’s browser capabilities. If WebP is not supported, the original format (e.g., JPEG, PNG, GIF) will be served instead.
