How to reduce the size of a PDF file offline on a smartphone

Mobile apps are full of ads and rarely provide a compression feature in the free version, so we recommend using online services on smartphones. Moreover, they work well on different devices. However, here are a couple of alternatives just in case.

1. Small PDF

Tap on the plus and select Add from files.

Find the desired PDF file and open it, then select Compress… from the application menu.

Specify the compression level (only basic is available in the free version) and wait a bit. The finished file will appear on the main tab, from where it can be copied to another application through the "Share" menu.

2. Files

The built-in file manager in iOS, among other things, can compress PDF, so iPhone owners don't have to install anything.

Open "Files", find the desired PDF and, holding your finger on it, select "Optimize file size" in the "Quick Actions" section.
