JPG Progressive
jpg-progressive
Specifies whether or not a JPEG is loaded as a Progressive JPEG (jpeg-progressive=true
) or as a Baseline JPEG (jpeg-progressive=false
).
The default value is true
when not specified if the output format is a JPEG. If the output format is not a JPEG, then this parameter will have no effect.
Progressive JPEG (default value)
A Progressive JPEG loads in layers until the image is fully loaded. As a no-code alternative to lazyloading (opens in a new tab), this approach is especially useful for web images, allowing users to get a sense of the image content even with slow internet speeds.

Baseline JPEG
A Baseline JPEG loads from top to bottom. This method does not give an immediate view of the entire image at a lower quality but instead reveals the image in sections as it loads.
