Why Compress a PDF File?

Compressing a PDF file isn’t just about saving space—it’s about making your workflow smoother.

It also helps optimize storage on your computer or cloud service, leaving room for more important things. With pdfFiller, you can compress PDF files without losing quality, keeping your documents sharp and professional.

Compressing PDF Files on Windows

Windows users have solid free options to compress PDFs without needing extra software subscriptions. Here’s how to do it using tools you might already have or can easily get.

Using Microsoft Word

Microsoft Word isn’t just for typing—it can double as a PDF compressor. Follow these steps:

  1. Open Your PDF: Launch Microsoft Word and click “File” > “Open.” Select your PDF. Word converts it into an editable format automatically.
  2. Save It Smaller: Go to “File” > “Save As” and pick “PDF” as the format. Before saving, click “Options” and choose “Minimum size (publishing online).”
  3. Click Save: Hit the save button, and you’ll have a compressed PDF ready to go.

This works well for basic compression, though it’s light on customization.

Compressing PDFs on Mac

Mac users can also compress PDFs without spending a dime, thanks to built-in features and free online options. Here’s how.

Using Preview

Preview, the default PDF viewer on Mac, makes compression simple. Here’s what to do:

  1. Open the PDF: Double-click your PDF to launch it in Preview. If it doesn’t open automatically, right-click and choose “Open With” > “Preview.”
  2. Export with Compression: Click “File” > “Export” in the top left corner. In the dialog box, find the “Quartz Filter” dropdown and select “Reduce File Size.”
  3. Save It: Pick a spot to save your file and click “Save.” Your PDF is now compressed.

It’s fast and free, though it might lower image quality more than you’d like.
