Block poster maker 1

Create, preview, and print tiled posters from photos or AI art. BlockPoster.ai is an online block poster maker that turns a photo or AI-generated image into a large poster printed across ordinary sheets of paper. Users can crop an image, choose paper size and poster dimensions, adjust margins and overlap, preview the tiled layout, and download a PDF with assembly guides. Photo uploads and PDF pages are processed locally in the browser. Free PDFs include a watermark and are limited to 150 DPI and five sheets across; paid options provide watermark-free HD downloads and AI image-generation credits.
