Shrink a PDF so it fits email and upload limits, without sending it to a server.
Runs on your device. Your file is not uploaded.
Free to open and preview. Downloading the result needs PDF Tower: $89.99 a year or $12.49 a month. See pricing
What it does
PDF Tower rewrites the file on your device, recompressing images and removing unused data, and shows you the new size before you save.
How it works
- Choose a PDF.
- Pick a compression level and check the new size.
- Download the smaller PDF with a PDF Tower plan.
