Why Edit PDFs on Android?

Android devices have some unique advantages when it comes to PDF editing:

Seamless Google Drive Integration
Your PDFs are likely already in Google Drive. With Android, you can open PDFs directly from Drive, edit them in BoostPDF, and save back to Drive - all without leaving your phone.

Works on All Android Devices
From budget phones to flagship Samsung Galaxy and Google Pixel devices, BoostPDF works the same way. One tool that works across all Android versions and manufacturers.

S Pen and Stylus Support
If you have a Samsung Galaxy Note, Galaxy S series with S Pen, or any Android tablet with stylus support, you can use it for precise drawing and signatures. The pressure sensitivity makes signatures look natural.

Split-Screen Multitasking
Android's split-screen mode lets you view the PDF in BoostPDF while referencing another document or email in the other half of the screen. Perfect for filling out forms with information from elsewhere.

Android Share Menu
Once you've edited your PDF, use Android's powerful share menu to send it via Gmail, WhatsApp, Slack, Google Drive, or any app installed on your device. One tap, infinite options.
