There is also an HYPERLINK "https://en.wikipedia.org/wiki/Interlace_%28bitmaps%29"interlaced "Progressive JPEG" format, in which data is compressed in multiple passes of progressively higher detail. This is ideal for large images that will be displayed while downloading over a slow connection, allowing a reasonable preview after receiving only a portion of the data. However, support for progressive JPEGs is not universal. When progressive JPEGs are received by programs that do not support them (such as versions of HYPERLINK "https://en.wikipedia.org/wiki/Internet_Explorer"Internet Explorer before HYPERLINK "https://en.wikipedia.org/wiki/Windows_7"Windows 7)HYPERLINK "https://en.wikipedia.org/wiki/JPEG"[13] the software displays the image only after it has been completely downloaded.
