So im a primary student that just started to use coreldraw for my task of making a design of a food packaging. So there's 2 image, one is a background and one is a nugget pict with transparent background that i downloaded from google. I put the nugget pict above the background pict, then i save the file as a PNG. When i open the file, the nugget pict still has the transparent background shown, which is a mosaic background that covers the first background image. Can someone help me how to get rid of this mosaic transparent background?
If you are referring to this mosaic....
Then the file you downloaded was not transparent. Generally, you need to follow the link to a "Download" button to get the file you are after.
Try going back to the file and looking for some link that says "Download this file now" or "Download Original"
