Block Poster Pro
Turn images and documents into tiled printable poster PDFs
About Block Poster Pro
Block Poster Pro is for people who want a large wall print but only have ordinary office or home printers. Upload an image, or start from a PDF, TXT, Markdown or DOCX file, then pick a paper size, orientation and number of pages wide. The app shows the page grid before export, so the page count is clear up front.
The tool exports a PDF split across standard sheets with options for margins, overlap, contain or cover fit, and cut marks. Each page carries row and column labels, which makes assembling a multi-sheet poster easier. Processing runs in the browser, and the site notes that free exports include a watermark.
Its main difference from a generic PDF splitter is that paper proportions, margins and overlap are built into the grid, so the printed sheets line up when you tape them together. Teachers, makers, event planners and anyone printing a large temporary sign are the likely audience.
