Compress PDF

Makes a PDF much smaller by rewriting every page as a JPG image. Ideal for scans and job applications that are otherwise too large to email.

How it works
  1. 01Choose a PDF or drag it into the box.
  2. 02Choose a level: “Medium” is usually enough. “Strong” for viewing on a screen, “Light” if you still want to print it. Grayscale saves extra space.
  3. 03Tap “Compress PDF” and download the smaller file. Your original stays unchanged.

Every page is drawn in your browser, saved as a JPG and placed in a new PDF, at the original size of the page. That is why scans and photos shrink a lot, while text-only PDFs hardly shrink at all: They are already very compact, and the tool then tells you so instead of offering you a larger file. Large PDFs with many pages take a few seconds per page, a little longer on a phone.
