How to Reduce a PDF's File Size

Updated

A form says your PDF must be under a certain size, and yours is far over it. Most of the time, the fix takes a few minutes once you know what's making the file large.

Why is your PDF so large?

CauseHow much it can shrink
Scanned pages or phone photosOften a lot, as every page is a picture
Photos in a report or brochureOften a lot
Mostly textLittle. It's probably small already
Many pagesDepends. Removing pages may help more

Step 1: compress it

Upload the file to Compress PDF and choose Balanced. The page shows the old and new sizes straight away. If it's still too large, go back to your original and choose Smallest file.

Step 2: remove what you don't need

Every page adds to the size. Blank pages, old attachments and extra copies can go with Remove PDF Pages. If you only need part of the document, use Extract PDF Pages instead.

Getting down to a small limit such as 200 KB

A very small limit is hard to reach with several scanned pages. There's no setting that hits an exact size, so try these in order:

  • Use Smallest file, and check whether the result is enough.
  • Rebuild plain typed pages with the Black and white style in Scan to PDF, which can make them smaller, and then compress the result.
  • Send fewer pages, if the form allows it.
  • Split a long document with Split PDF, if you can upload more than one file.

Check before you send

Open the small file and zoom in on names, dates and numbers. A form is no use if nobody can read it. If small print has become unclear, use a gentler level and find the size elsewhere, such as by removing pages.
