What is Block Poster Pro?
Block Poster Pro makes it easy to turn images, PDFs, TXT, Markdown, and DOCX files into big printable posters. You upload your file, pick paper size and orientation, choose how many pages wide you want the poster, and get a preview of the tiled layout before export. The app runs in the browser for the current image workflow, so it feels fast and private. It includes practical print controls like margins, overlap, contain or cover fit, cut marks, and row or column labels to help you trim and assemble the pages neatly. It is built for everyday printers, so you can create wall-sized prints at home, at school, or in the office without using a wide-format printer.
