Choose the file you actually need
The image splitter exports PNG, JPG or WebP pieces, individually or together in a ZIP with their source coordinates. The poster maker exports a PDF with one poster tile per paper sheet. The contact sheet maker places several images together in a PDF. The calculator works from pixel dimensions and needs no image file.
A practical starting point
Working with paper? Start with the poster maker and check the page count before exporting. Working with separate digital crops? Use the splitter. Need help with printer scaling or tile boundaries? The guides explain the choices with small examples.
