The quality of the enlargements is great. Yet the image upload size is a problem for me. You can not upload anything over a3 size, or 4000 px. I also get a 5mb limit but sometimes this has changed to 10 mb, i do not know why. I try to upload a 3990 x 3990px image, to try and enlarge to 16000px image. Yet every time it says the image is to many mb. I noticed the link to tinypng to shrink the image but the free version is omly up tp 5mb. Tinypng paid version is up tp 75mb, Why is this software so redtrictive? As much as i love it, it is no good to me.Shame.
