How to Print a Large Image on Multiple Pages on PC or Mac

Using Rasterbator to Enlarge the Image

1. Go to https://rasterbator.net/ in a web browser. The Rasterbator is a popular website known for creating poster-sized wall art. This site works for both Windows and macOS.

2. Click Create your poster.

3. Select a source image. There are three ways to do this:

   1. If the image is online, type or paste its direct URL into the 'Load from URL' blank, then click Load.
   2. If the image is on your computer, click Browse… to open your computer's file browser, select the image, click Open, and then click Upload.
   3. Another way to upload an image from your computer is to drag it from a folder to the the 'Drag image file here' box.

4. Select your paper settings. Under 'Paper settings,' choose your desired options:^[1]

   1. Choose the size and format of the paper you're printing on, such as A5 (5.8' x 8.3) or US Letter (8.5' x 11'), from the first drop-down menu.
   2. Select either the Portrait (tall) or Landscape (wide) format.
   3. The default margin size is 10 mm, which should work for most home printers. Margins are necessary because most printers don't print all the way to the edge of the paper. If the margins are too small, some of the image will be cut off—if it's too big, you can always just trim off the edges.
   4. Overlap makes it easy to join the images together when you cut off the margins because the image will slightly overlap onto the adjoining sheets. Check the box 'Overlap pages by 5 mm' box for best results.

5. Choose the size of your poster. The 'Output size' section determines the size of your poster based on the number of sheets making up the image. The higher the number of sheets, the larger the size of the poster.

   1. Enter the number of sheets into the first box.
   2. In the drop-down menu, select wide or high.
      1. For example, if you type 6 into the 'sheets' box and select wide, the image will be the size of 6 sheets of paper across (wide). Rasterbator will figure out how many sheets tall the poster must be to fit the image.
      2. If you select tall, the example image would be 6 sheets tall, and Rasterbator would determine the width based on the image size.
   3. The grid lines on the preview show how many sheets of paper you'll be using.

6. Click Continue.

7. Select a style. Rasterbator lets you choose from an assortment of styles to add an artistic effect to your poster. Click a style (a preview will appear on the image), or select No effects to skip this step.

   1. Rasterbation and Black and white rasterbation are popular choices that print in a halftone style, comprised of many dots.

8. Click Continue.

9. Select your color preferences. If you selected a style, you'll be able to choose additional options for the final product.

   1. If you chose No effects, none of these menu options will affect your poster.

10. Click Continue.

11. Select your final style options. These options will vary depending on the style you selected.

    1. If you did not select a style, you can still browse through the drop-down menu at the top of the screen to add some effects to your final product. If you decide not to use any, select Enlarge from the menu.
    2. To make it easy to trim off the margins, check the box next to 'Crop marks.' This is optional, and is not necessary if you added the 5mm overlap.

12. Click Complete X page poster!. The 'X' represents the number of pages you're printing. The site will now build your image.

13. Download the PDF. Click OK or Save (the options vary by computer and browser) to download the finished image that's ready to print.
