Jpg2pdf PRO is an upgraded version of the jpg2pdf software.
Another great feature of jpg2pdf PRO is its automatic detection of the jpeg image type, whether it is rgb, gray, or cmyk, and then creating the correct pdf accordingly. Furthermore, this software can automatically check if the jpeg image is rgb, gray, or cmyk and then create the correct pdf or pdf album.
One thing to note is that jpg2pdf PRO goes the extra mile in detecting cmyk images that are made by Adobe Photoshop. In this case, the software will use inverted colours to create the pdf, as it appears that Adobe Photoshop writes inverted data in CMYK JPEG files. This means that 0 represents 100% ink coverage instead of the expected 0% ink coverage.
Overall, if you need a powerful jpeg to pdf converter that offers advanced features and automatic image detection, jpg2pdf PRO is the way to go.
