You can easily reduce document size and compress your PDF files on Mac using the Preview app and Xodo's online PDF compressor.

Dealing with large PDFs you can’t email? Running out of storage space on your Mac?

Good news! Compressing PDFs on your Mac is easier than you think.

You already have the Preview app on your device, and you can also use Xodo to reduce the size of your PDFs online, from any browser.

So let's make your PDFs more manageable and easier to share.

How to Compress a PDF on Mac with Preview

You can use the Preview app to quickly compress your PDF on Mac. Simply follow these steps:

  1. Open Preview.
  2. Open the PDF you want to compress.
  3. Go to File > Export.
  4. Select Reduce File Size In the Quartz Filter drop-down menu.
  5. Click on Save.

Note that this method is ideal for common PDFs that contain simple text, graphics, or other visual elements.

However, for documents composed mainly of images or high-resolution photos, such as digital brochures, magazines, or print productions, this method is not as effective.

A more efficient compression tool like Xodo should be used.
