 - `width` - The intrinsic width of the source image in pixels. Must be an integer without a unit. Required unless `unsized` is true.
 - `height` - The intrinsic height of the source image, in pixels. Must be an integer without a unit. Required unless `unsized` is true.
 - `sizes` - Defines what proportion of the screen you expect the image to take up. Recommended, as it helps serve the correct sized image to each device. [More info](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/img#attr-sizes).
-- `quality` - The quality of the optimized image, an integer between 1 and 100 where 100 is the best quality. Default 100.
+- `quality` - The quality of the optimized image, an integer between 1 and 100 where 100 is the best quality. Default 75.
 - `loading` - The loading behavior. When `lazy`, defer loading the image until it reaches a calculated distance from the viewport. When `eager`, load the image immediately. Default `lazy`. [More info](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/img#attr-loading)
 - `priority` - When true, the image will be considered high priority and [preload](https://web.dev/preload-responsive-images/).
 - `unoptimized` - When true, the source image will be served as-is instead of resizing and changing quality.
