Posterize PDF
Divide each page of a PDF into a grid of smaller sub-pages. This is the tool for printing a single page across multiple sheets of paper, which you then tile together to create a large poster or banner.
How It Works
- Upload a PDF file.
- Set the number of rows and columns to define the grid (e.g., 2 rows x 2 columns splits each page into 4 sub-pages).
- Optionally specify a page range to limit which pages get posterized.
- The preview canvas shows a grid overlay on the current page so you can visualize the cuts.
- Navigate between pages to check the overlay on different pages.
- Click the process button. Each grid cell becomes its own page in the output PDF.
Features
- Configurable row and column count for flexible grid sizes
- Live preview with grid overlay showing exactly where pages will be divided
- Page range filter to posterize only specific pages
- Page-by-page navigation in the preview
- Cached page snapshots for fast preview navigation
- Dashed red grid lines clearly mark the cut boundaries
Options
| Option | Description |
|---|---|
| Rows | Number of horizontal divisions (default: 1) |
| Columns | Number of vertical divisions (default: 1) |
| Page range | Which pages to posterize (blank = all pages) |
Use Cases
- Printing a poster-sized PDF across standard A4 or Letter sheets to assemble on a wall
- Creating large banners from a single-page PDF design
- Splitting oversized technical drawings into printable tiles
- Making large-format prints without access to a wide-format printer
Tips
- A 2x2 grid turns one page into 4 pages. A 3x3 grid turns one page into 9. Plan your grid based on how large you want the final assembled output.
- The preview overlay helps you verify that important content does not fall on a cut line. Adjust rows/columns if needed.
- For the reverse operation (fitting multiple pages onto one sheet), use N-Up PDF.
