About Block Poster
Block Poster is a free online tool that helps you create large wall posters from any image using your regular home printer.
Our Mission
We believe everyone should be able to create beautiful large-format prints without expensive professional printing services or specialized equipment. Block Poster makes it simple: upload an image, configure your grid, and print.
Your Privacy Matters
Block Poster processes everything in your browser. Your images are never uploaded to any server. We don't use cookies for tracking, and we don't collect any personal data. Your creative work stays completely private.
How It Works
Block Poster uses modern web technologies including the HTML5 Canvas API for image processing and pdf-lib for PDF generation. Everything runs client-side in your browser, which means your images never leave your device.
