The same collage looks different on an A4 sheet, a 20×30 photo print and a channel banner — each format has its own proportions and resolution needs. So the photos don't get cropped or stretched, it's easier to set the canvas to the target format up front instead of adjusting it at the end. Choose a format from the list and the editor opens at the right size — all that's left is to arrange your photos.
For print, quality matters as much as proportion: the A4 and 20×30 layouts are built for high resolution so the print stays sharp, and the PDF export runs at 300 DPI. Social covers, on the other hand, are matched to each platform's exact dimensions so nothing hides behind an avatar or the interface. Every format is built online, right in the browser, free and without sign-up.
