What you need
Just an image (PNG or JPG) and a printer. No design software, no account, nothing to install. The whole block poster generator works online, on Windows, Mac, Linux, iPad, or phone.
Step 1 — Upload your image
Drag your photo onto the uploader, or paste an image URL. Your image stays in your browser — it is never uploaded to a server — which makes this a great privacy-first blockposters alternative.
Step 2 — Choose your size
Pick how many pages wide the poster should be (1–10), the paper format (A4 or US Letter), portrait or landscape, and whether each page has a border. The tool shows the final poster size live, so you know exactly how big it will be before you print.
Step 3 — Generate the PDF
Click Generate PDF. You get a multi-page file — one tile per page — with alignment marks so the sheets line up neatly when you assemble them.
Step 4 — Print and assemble
Print every page at 100% scale (turn off "fit to page"), then tape or glue the sheets together following the marks. Hang it up — your block poster is ready.
