OpenOffice is a free, multi-OS office productivity suite which allows users of many different systems to share office files. Keeping these files at a manageable size is important for efficiency of data transfer and minimal use of storage space. A file that can be read by many operating systems for free is useless if it's too huge to send efficiently. Images can be compressed in OpenOffice using an "extension" add-on and a few simple steps, saving space and creating smaller more manageable file sizes.
Things you need
Visit the OpenOffice Extensions website (found below in Resources) and click the "Get It" link that corresponds to your operating system to get the Presentation Minimizer extension. An automatic install wizard will open in a new window. If it does not automatically begin, click the link marked "here" to manually begin the installation.
Read the license agreement and click "accept". The OpenOffice Extension Manager will open in a separate window and install the Presentation Minimizer extension. The next time you start OpenOffice this extension will be available for use.
Open OpenOffice and click "Presentation." This will open up the OpenOffice Impress presentation-making program. Once Impress has begun, click through the steps in the Create Presentation wizard to set up your presentation.
Look for a small window labelled "Minimizer" once the Create Presentation wizard has finished and the presentation is available for viewing. Click on "Minimize Presentation." This will open a Minimizer wizard which will let you choose how to compress your photos.
Click on step "3. Graphics." This menu offers the options "Lossless compression" and "JPEG compression." Lossless compression will compress the images without loss of detail but save less space. JPEG compression lets you choose the percentage of quality lost to compression and save more space.
Click "Finish" once you have made your compression selections. A Save As dialogue will open.
Type in a filename and click on the desired location for the file. Click "Save". A copy of the presentation with compressed images will now be available at the save location.
