How to Make PowerPoint Images in 300DPI for PDF

By Stephanie McCampbell

Dots per inch or "dpi" is a measurement of the quality of an image. Typically, the higher the dpi, the better the quality of the image. A high-quality image is important for printing posters or other large format images or graphics. Adobe Acrobat Professional files are called Portable Digital Format or "pdf," a high-quality digital file suitable for use in commercial offset printing. Converting your PowerPoint slide to a .pdf will make it acceptable for high-quality, larger format printing.

Step 1

Open the slide presentation in Microsoft PowerPoint. Click "Print."

Step 2

Click the drop-down menu arrow next to "Name" in the print pop-up window menu. Select "Adobe PDF," as your printer. Click the "Properties" button located right next to the printer name drop-down menu.

Step 3

Select the "Adobe PDF Settings" tab. Place a check mark in the "View Adobe PDF Results" box to allow Adobe Reader or Professional to open your .pdf file for viewing.

Step 4

Select the "Layout" tab and click the "Advanced" button. This will open up the "Adobe PDF Converter Advanced Document Settings" pop-up menu. Click the "Plus Sign" next to the "Graphic" menu option to expand the graphic options.

Step 5

Click the "dpi" setting next to "Print Quality," in the graphic options, to change the dpi. A drop-down menu should appear to allow you to change the dpi settings. Select "300 dpi" from the menu. Click "OK" to close the options pop-up window. Next click "OK" to close the "Adobe Document Properties" pop-up window.

Step 6

Click "OK" once more to close the "Print" pop-up window and open the "Save As" window. Name your file in the "File Name" dialog box and be sure to check that the "Save As" type is set to pdf. Select the location to save the pdf file. Click Save to create your pdf. Once the conversion is complete, your pdf will open in your Adobe Acrobat program.
