convert PDF to JPG doesn't do high-quality images
Your PDF to JPG file converter doesn't give very impressive results sorry!
Note the original is 1500x1200mm and nice clean lines and text but when I ask it to convert to JPG (or PNG or TIFF) with High or Max size, it pops out a piddly little 24KB file of 1024x820 pixels!
Thanks for using Acrobat web and providing your feedback. We are currently reviewing your issue internally and will get back on this.
