About PDF Viewer

PDF Viewer (Package Name: app.grapheneos.pdfviewer.play) is developed by GrapheneOS and the latest version of Secure PDF Viewer 31 was updated on August 31, 2025. Secure PDF Viewer is in the category of Productivity. You can check all apps from the developer of Secure PDF Viewer. Currently this app is for free. This app can be downloaded on Android 8.0+ on APKFab or Google Play. All APK/XAPK files on APKFab.com are original and 100% safe with fast download.

Simple Android PDF viewer based on pdf.js and content providers. The app doesn't require any permissions. The PDF stream is fed into the sandboxed WebView without giving it access to the network, files, content providers or any other data.
Content-Security-Policy is used to enforce that the JavaScript and styling properties within the WebView are entirely static content from the APK assets along with blocking custom fonts since pdf.js handles rendering those itself.
It reuses the hardened Chromium rendering stack while only exposing a tiny subset of the attack surface compared to actual web content. The PDF rendering code itself is memory safe with dynamic code evaluation disabled, and even if an attacker did gain code execution by exploiting the underlying web rendering engine, they're within the Chromium renderer sandbox with less access than it would have within the browser.

PDF Viewer 31 Update

Notable changes in version 31:
• minor fixes for edge-to-edge support
• fix issue causing the text layer used for text selection to not rotate when the PDF is rotated within the app
• enable hardware memory tagging for use outside of GrapheneOS in the narrow cases where it's available
• update pdf.js to 5.4.149
• update other npm dependencies
• update AndroidX libraries
• update Android SDK and toolchain
