What is The Maximum Size of a PDF That Can Be Compressed?

When dealing with large PDF files, compressing them becomes essential. Whether you’re sharing documents via email, uploading them to a website, or simply saving space on your device, reducing the file size can significantly improve efficiency. But what is the maximum size of a PDF that can be compressed?

Understanding PDF File Sizes

Before we dive into compression techniques, let’s understand how to determine the size of a PDF. You can check the file size using Adobe Acrobat or free Adobe Acrobat Reader:

Using Adobe Acrobat or Adobe Acrobat Reader:

  • Open the PDF file.
  • Go to File > Properties.
  • Look for the file size listed in the “Document Properties Description” tab.

  • Select “Get Info.”
  • Review the 'File Size' to ascertain the exact dimensions.

On a PC:
