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, this approach is especially useful for web images, allowing users to get a sense of the image content even with slow internet speeds.

Example of an image output as a progressive JPEG (jpeg-progressive=true): Example of an image output as a progressive JPEG (<code>jpeg-progressive=false</code>)

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.

Example of an image output as a baseline JPEG (jpeg-progressive=false): Example of an image output as a baseline JPEG (<code>jpeg-progressive=false</code>)

See the API specification for more information about this parameter's value ranges and format.
