Is it safe to compress sensitive PDFs on an Android phone?
With PdfXpo, it is the safest method available. Because our technology uses local browser-based processing, your files never leave your Android device.

Do I need a specific browser to use PdfXpo on Android?
PdfXpo is optimized for Google Chrome, which is the default for most Android users, but it also works flawlessly on Samsung Internet, Opera, and Firefox. As long as your browser supports modern web standards and WebAssembly, you can enjoy fast, local PDF compression with no additional setup.
Can I save my compressed PDF directly to Google Drive on Android?
Yes. When you download your optimized PDF from PdfXpo, your browser will save it to your local 'Downloads' folder. You can then use the 'Share' or 'Upload' function within Android to move that file directly into Google Drive, OneDrive, or any other cloud storage service of your choice.
