Rasterbator.app
Turn any image into a wall-sized tiled poster PDF
Rasterbator.app turns any photo into a printable multi-page poster PDF directly in your browser. Choose A4, Letter, A3, or a custom page size; set the page grid, margins, overlap, crop marks, and optional halftone effects; then download a ready-to-print PDF. Local files stay in the browser, no account is required, and generated PDFs have no watermark.
