How to make a PDF smaller
Drop your PDF in the box, choose a level and press Compress PDF. The result shows the size before and after. "Light" keeps your text; "Balanced" and "Strong" save more space by turning each page into a picture.
Common mistakes
- Using Balanced or Strong on a PDF you need to search or copy text from: the text becomes part of the picture.
- Opening a PDF with a password: remove the password first, the tool cannot open it.
