How to compress a PDF

Shrink oversized attachments so they sail through email limits.

Step by step

  1. 1

    Upload your PDF and note the original size shown on screen.

  2. 2

    Pick Low, Medium or High compression.

  3. 3

    Run the compression and compare the before and after sizes.

  4. 4

    Download the smaller file if you are happy with the result.

Pro tip

Scanned documents benefit most; text-only PDFs are already close to optimal.
