Install Checklist

Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
File size is a light 14.04 MB, so it installs quickly even on modest connections.
This build is signed by "Michael Troger" — always verify the developer name matches what's listed on the app's official store page before installing an update.
After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

Frequently Asked Questions

Is PDF Wallet free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does PDF Wallet require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is PDF Wallet safe to install?
We link to the exact APK published by Michael Troger. We do not modify the file. Still, as with any sideloaded app, scan it with a reputable antivirus before opening it, and only grant permissions the app genuinely needs.
