While designing content for your Digital Displays I am sure you have run into the issue when saving your files and asked yourself "Which file format should I use?" There are advantages to both file formats however understanding why one is better than the other will bring many benefits such as quicker file transfers and less storage space required.
JPG's
JPG is a popular file format typically used because of its ability to provide great looking photos and images while keeping file sizes low. You will be surprised at how much smaller your files can be if you save them as a JPG vs a PNG. You just need to make sure that you do not need to have a transparent background and the level of quality of the JPG is acceptable for your application.

Can you see a difference? Well neither will most of your viewers however the PNG will be almost 10x larger then the JPG of the same image! The JPG file comes in at a reasonable 1/2 a meg while the PNG file is almost 5 megs.
Now lets pretend for a moment that you have 10 images. That means if you used JPG you would have approximately 5 megs total to upload. On the other hand if use PNG you would need to upload nearly 50 megs of data! Not only will using JPG for your photo's save you time when uploading your photo's, you'll also notice that your players will load the images much quicker as well!
JPG result in more data loss then PNG
These benefits however result in the loss of image data and results in a decrease in image quality. If you look carefully at these zoomed in images you will notice that the crispness has been lost in the JPG (first image) and this will get progressively worst the more you edit and save the image. If you plan on doing any additional photo editing or changes in the future I would highly recommend using PNG instead to preserve the quality of your image.
PNG's
PNG is a lossless image format meaning that it will preserve all the original data in the original image. The problem is all that data takes up a lot of room and if you are saving photo's you can eat up a lots of memory very quickly. I would only recommend using this format if you have a need to insure that no quality is lost in the image (such as keeping a master copy of your picture for editing) or if you need to have a transparent background. This can be a very important issue when designing your content as you may want to do things such as have a logo placed over your background image.
