Your audience can only do so much. It is up to you the designer to deliver a
presentation that is optimized and robust enough to be emailed downloaded
or printed if you plan to share with your audience.
After adding images to your PowerPoint presentation, your PowerPoint file (PPT)
may become very large. For example, I have one PPT of three slides and five
pictures that is over six megabytes! Such files are unwieldy, especially for
sending via email.. Email attachments are typically encoded in a format that
makes binary files expand. That six megabyte PowerPoint becomes ten megabytes
when sent as an attachment.
When you add pictures to PowerPoint, they are stored in an unutilized
format. For example, if you crop a picture, the parts that were cropped are
still taking up space (so you can un-crop later if needed). If the picture is at
high resolution, then the fine details remain regardless of how the picture is
reduced in height and width. For example, you might add a picture from a four
mega pixel digital camera that is 2000 by 2000 pixels in size. If you resize this
to a 1 inch square in the PowerPoint slide, the resolution will be 2000 dots per
inch (dpi)! By comparison, recommended print resolution is 200 dpi while screen
resolution is only 96 dpi.
For typical print or screen viewing, you can remove the fine detail and
cropped parts of the pictures to reduce the file size. PowerPoint 2003 (or 2007)
has a built-in feature to compress the pictures in a presentation. Also do not
embed pictures that are of a BMP format . BMP files do not compress use Jpg or
gif files formats instead To compress pictures, follow these simple steps:
Once the picture is inserted in the Presentation then click the Compress
Pictures option under Format > Picture Tools
Now be sure to check the Delete cropped areas of pictures option to
reduce the overall size of the presentation. Also select the appropriate target
The six megabyte file I described above becomes 200 KB when pictures are
compressed for the web, and 500 KB when compressed for printing. That represents
an order of magnitude reduction in file size. Remember, by compressing the
presentation, you lose the cropped parts of the pictures and the fine detail of
the pictures. If you need those again, make sure to save the original
presentation or the original pictures.
PowerPoint files don't always print the way they look on-screen. About 30% of
PowerPoint files encounter problems when moved from one computer to another --
graphics disappear or misprint, text and labels shift position, Greek letters
vanish. or the printer output is nothing but error codes. To further
complicate matters you may find the MAC or Linux users can print or download
your PowerPoint presentations because they may not have a compatible application
to view PPT files. Saving your power point presentation to another file in
a PDF format can greatly increase the success of sharing your document with
- Click the Microsoft Office Button,
point to the arrow next to Save As, and then click
PDF or XPS.
- In the File name list, type or select a name for the
- In the Save as type list, click PDF.
- If you want to open the file immediately after saving it, select the
Open file after publishing check box. This check box is
available only if you have a PDF reader installed on your computer.
- Next to Optimize for, do one of the following, depending
on whether file size or print quality is more important to you:
- If the presentation requires high print quality, click
Standard (publishing online and printing).
- If the print quality is less important than file size, click
Minimum size (publishing online).
- To specify various options for the file, click Options.
(Find links to more information on these options in the See Also
section.) Click OK.
- Click Publish.
If you want to make changes to the PDF after saving it, return to your
original 2007 Microsoft Office system file in which you created it and save the
file as PDF again.
