Block Poster Maker
Image Generation
"BlockPoster.ai is a browser-based block poster maker for turning one image into a large poster you can print and assemble at home. Upload a JPG, PNG, WebP, or PDF page, or create original artwork with AI, then choose your paper size, orientation, poster width, margins, overlap, crop behavior, and Fit or Fill mode. The workspace shows a live poster grid before export, so you can see how many sheets your design will use and how the final image will be divided.
