What Block Poster is
Block Poster is a web tool that divides an image into printable pages for assembling a large poster with a home printer. It accepts JPG, PNG, and WebP files and provides controls for paper size, page count, orientation, margins, and overlap, with a live layout preview. Supported paper sizes include A4, US Letter, A3, Legal, and Tabloid. The free plan exports one PDF up to 300 DPI, adds no watermark, and requires no account. BlockPoster Pro adds Batch Studio for up to 10 images, with a combined 50 MB limit, 20 megapixels per image, and 100 total print pages excluding covers. Each image becomes its own tiled PDF, downloadable separately or together in a ZIP. Pro costs $4.99 a month or $39 a year. Images and project content are processed locally in the browser. Browser drafts and named presets may disappear if browser data is cleared, so downloaded files can serve as backups.
