A 20×30 cm print is one of the most common sizes at photo labs: frames are easy to find for it, it fits in an album and looks good on a shelf. A 20×30 collage gathers several shots into one print — handy for a gift, a family selection or holiday memories. The canvas opens straight away in a 2:3 ratio, so the frames sit evenly and nothing gets cut off at the edges when printed.
For a sharp print, the layout is built for high resolution — labs print 20×30 with room to spare on quality. Save the collage as JPG or PNG to upload to a print service, or as PDF if you take the file to a shop. Each photo inside the collage can be moved and zoomed, the background and gaps are adjustable, and there are no watermarks on the result. All free and without sign-up.
