Big ideas, ordinary paper.
You do not need a large-format printer to make something worth putting on your wall.
Rasterbator Online helps you split a picture across ordinary sheets of paper, download a printable PDF, and assemble a larger poster at home, in a classroom, or at work.
Made for the practical details
Paper size, margins and overlap affect how a poster fits together. Our workspace keeps those decisions visible, so you can see the sheet layout and finished image size before downloading. Original mode preserves the look of your picture; optional single-color or full-color halftone dots turn it into a graphic poster.
Your device does the work
Image processing and PDF generation happen in your browser. Your selected picture is not uploaded to us. The tool is free, does not add a watermark, and does not require an account.
An independent project
Rasterbator Online is independently developed. For questions about the website, contact support@rasterbatoronline.com. It is not affiliated with The Rasterbator or other Rasterbator sites. The general technique of printing a large image over smaller sheets is often called tiled printing; halftone rendering represents light and shade with dots.
