While JPG files are good for image formatting and circulation, there are limits to what you can efficiently do with a JPG. It is not easy, for example, to work on a JPG image that has been edited more than once, nor is it easy to print a good quality JPG either.
Every time you save your edited JPG, the lossy compression which JPGs use will start deleting extra data (in the form of pixels) to make smaller files.
Thus, you will not be able to add image effects without affecting the quality. The quality of a printed JPEG also depends on pixel dimension. Besides the pixel loss during compression, the pixel dimensions for print and screen are different and your printed JPG may differ than the one on screen.
To solve this, simply use the PDF format. Professionals working in all types of image and graphic design production are wary of the importance of converting JPG into PDF file.
