Large-format posters from your browser

About Rasterbator

Rasterbator helps you turn photos, illustrations, and blueprints into multi-page posters you can print on standard paper. You choose the scale and style, then export a print-ready PDF or ZIP from the same workspace.

Local Processing by Default

Poster previews and exports are generated in your browser. We do not run a server-side image pipeline for your uploaded source images.

Free Access, Supported by Ads

Rasterbator is free to use. To support maintenance, we may use advertising placements and will disclose ad technology in this policy set.

Clear Policies

Our About, Privacy, and Terms pages are written as product documentation: what happens to your data, what the service guarantees, and what it does not.

Privacy and Terms Stay Separate

Operational contact details live with the legal pages so product claims, privacy commitments, and policy updates stay in one consistent place.

Static Poster Workflow

Rasterbator stays focused on browser-local poster generation: choose a file, tune the grid, then export printable pages without accounts or a server gallery.
