Delphi’s JPEG library is very slow. How to improve its performance? I am looking for a fast Jpeg library-save and load jpeg images faster.
I only tested Jpeg.TJPEGImage
You can use libJpeg or libJpegTurbo. The latter is definitely very fast.

libJPEG Header conversion by Steffen Xonna. (21-03-2008)

Below you find an copy from the original libJPEG header.
