How to Reduce PDF File size

One of the downsides to creating a great PDF is the resulting large file size. Bloated PDFs take up too much space, are very inconvenient to the user, and can even slow down a computer. Luckily, there are ways to get rid of that excess baggage.

When attempting to reduce file size, you may want focus on removing disposable objects and reducing the size of images. Adobe Acrobat 9 Pro offers some of the most convenient options for doing so. If you need to shrink PDF file sizes down, you can try three different methods.

Use the Save As command in Adobe Acrobat 9 Pro:

  • step 1Choose Save As from the File menu. Instead of just adding on the changes you make with the regular Save function, the Save As option will shrink PDF file sizes by re-writing the entire file into a smaller one and eliminate the bloat.

  • step 2In the Images Settings section, choose a level of downsampling for your images.
  • When you downsample, you are actually decreasing the number of pixels in an image, ultimately deleting excess data from the overall file. With the right settings, you can reduce the size of a PDF file significantly while keeping the quality of detail.
