What Is PDF Compression?

PDF compression is the process of reducing the size of a PDF file. It can make documents more convenient to upload, email, store, and share. The amount of size reduction depends on the PDF's contents and the compression method used.

  • Smaller file size: Reduce the space a PDF occupies.
  • Easier sharing: Make documents more convenient to send.
  • Faster uploads: Smaller files can be easier to upload when connection speed is limited.
  • Document storage: Help manage collections of PDF files.
  • Image-heavy PDFs: Files with images may have more room for size reduction, depending on their contents.

  • Reduce the storage space used by supported PDF files.
