What does interlaced PNG mean?

Interlaced means that the image is first sent as a coarse image using each 8x8th pixel, then in each pass the resolution is doubled until the complete image is sent. This may give the impression of a blurry image showing up first that then improves in resolution when loading the image on a web page.

What is PNG compression level?

The ‘Compression level’ setting when saving PNG files determines the final file size of your image and also affects how long it will take to save. The highest compression rate (0 is lowest and 9 is highest) will make the smallest file, but it will also take the longest to save.
