We can prevent a lot of annoyance if we are well prepared and know the size of the image that will appear the best, before taking photos and posting them on social media. As like any new technology, social media changes fast. If the size of the image is larger than the given image size due to the much better resolution, it is worth to reduce the image size to its own size with an image editing program. For the best picture quality we should upload images with .png extension. Be aware when making graphics for Facebook ads, the text ratio can not pass 20%.
With this article we would like to give you some help to create the ideal appearance on social media surfaces.
