BlockPoster.ai

BlockPoster.ai lets you turn a single image into a wall-sized block poster spread across regular printer sheets. Upload a photo or generate artwork with AI, then crop, set paper size, margins, and overlap, and preview the layout before downloading a tiled PDF. You can start free with watermark-capped 150 DPI exports or upgrade for HD, watermark-free downloads up to 300 DPI, batch ZIPs, and monthly AI credits. Photos process locally in your browser for privacy and quick iteration. View startup
