Free and open source. Every release is checksummed and signed — verify your download.

What you're getting

A desktop application, not a web service. It opens PDFs from your disk, changes them, and writes them back. There is no account to create, nothing is uploaded, and every feature is available immediately — there is no paid tier to hold anything back.

Installing

Windows

Run the .exe. The build is Authenticode-signed, so Windows should install it without a SmartScreen warning. If you do see one on a brand-new release, SmartScreen reputation takes time to accumulate — check the publisher name, and verify the checksum if you want certainty.

macOS

Open the .dmg and drag the app to Applications. The build is not yet notarised by Apple, so the first launch needs right-click → Open rather than a double-click, which lets you approve it explicitly. Verifying the checksum first is a reasonable habit.

Linux

The .AppImage is self-contained. Mark it executable and run it:

chmod +x VerusPDF-linux-x64.AppImage
./VerusPDF-linux-x64.AppImage

Older versions

Every release stays available at a permanent versioned URL, so a build is never replaced or withdrawn. The pattern is https://downloads.veruspdf.com/v1.2.3/VerusPDF-windows-x64.exe, substituting the version you want. The release manifest lists the current version along with the size and SHA-256 of each file.
