U.S. Press Freedom Tracker

The U.S. Press Freedom Tracker is a website operated by Freedom of the Press Foundation (FPF) that brings together more than two dozen press freedom groups to systematically count and document all press freedom violations in the United States. The data we gather informs advocacy, journalism, and legal action.

The Tracker team also publishes a regular newsletter. Subscribe to stay informed about press freedom issues in the U.S.



Dangerzone is an open source desktop application that takes potentially dangerous PDFs, office documents, or images and converts them to safe PDFs. Dangerzone works on Windows, macOS, and Linux and uses container technology to convert the documents within a secure sandbox.

Dangerzone was originally created by Micah Lee, journalist/technologist and former FPF board member, and was inspired by the “Convert to trusted PDF” Qubes OS feature.



@FOIAFeed is an account on X, formerly known as Twitter, and Mastodon that highlights news stories that rely on the Freedom of Information Act, landmark U.S. legislation that protects the public’s right to request information from the government about its actions. FOIA is routinely threatened and undermined by public officials. We showcase its critical importance for public interest journalism, so that anyone can make the case for preserving and expanding FOIA access.
