Grab Scroll Anytime, Anywhere

It’s now possible to grab and scroll through the PDF pages even if the text-copying protection feature is disabled. Just click or touch anywhere within the previewer and move the pointer device.

NOTE: In the older version (2.0), this feature was automatically turned off if the text-copying protection feature was disabled.

Redefined Touchscreen Experience

Our team worked hard to improve touchscreen support to give you a more seamless PDF previewing mobile experience. You can now use your fingers to pinch zoom in/out and swipe to navigate anywhere within the PDF pages with ease! Perfect for viewing long documents on the go! 📑

Powerful and Adaptive in Many Ways
