Block Poster is a free online tool that turns any JPG, PNG, or WebP image into a tiled PDF for printing on standard paper sizes. All processing happens in your browser, so images never leave your device and no account or watermark is required. You choose the paper size, number of pages, orientation, and overlap, see a real‑time preview of the layout, and then download a multi‑page PDF. The tool supports A4, US Letter, A3, Legal, and Tabloid sizes and adds configurable overlap and margins to make page alignment straightforward. The service is aimed at educators, DIY crafters, home decorators, and event planners who need large‑scale prints without a print shop. It works on any modern desktop, laptop, tablet, or phone and requires no installation.
