Reduce the size of one or more PDFs to make them easier to share, upload, and store.
The Reduced Size PDF feature creates a smaller copy of your PDF. Smaller files require less storage space, transfer faster, and are easier to send by email or upload to websites and cloud services. You can also choose which Acrobat versions should support the reduced-size file.
