At MyPostcard, you are not bound to any specific formats, resolutions, or sizes, except that your picture should have a minimum resolution of one megapixel and should not be larger than 10 Mb. We will automatically adapt the size of the picture after your upload. During the process of adaptation, it is possible that some parts of your picture are cut off. However, you may check your picture within the preview and resize and move it as you like until the perfect cut-out is found. You may use pictures in 3:2 proportion as well as import square pictures e.g. from your Instagram archive.
