Essentially, you’re compressing an image twice and losing more and more quality along the way. When you upload a JPEG to Facebook, that image will be compressed again, this time by Facebook itself. Why PNG Works Better With FacebookĪs I mentioned above, JPEG uses a lossy compression and discards some of the information resulting in a loss of quality. Due to a wider range in color, shadows and gradients are much smoother in PNG-24. Photoshop gives you two different PNG options: PNG 8, which uses up to 256 colors, or PNG-24, which uses up to 16 million colors. PNG uses lossless compression and results in a bigger file size with better quality. JPEG uses a lossy compression this means that some information is discarded when it is saved, which in turn affects the quality of the image. JPEG- What’s the difference?īoth are file formats that use compression to reduce the image file size, however, each format uses compression in a slightly different manner. Using files smaller than 99kb is just good practice when it comes to website development, and it’s also advice that comes from Facebook itself. Why do I recommend keep image files under 99kb? I have found that using a PNG-24 format works best for my Facebook business page covers and a high quality JPEG works best for my personal Facebook covers. After I enter my desired hex code I check to see if Photoshop generates an error, in this case it did, which you'll see in the next screen shot. To be safe, I always choose the "Only Web Colors" option.
