Frequently Asked Questions

Why does my PDF automatically zoom in on mobile?

This usually happens due to a bug in specific versions of the PDF reader application, or occasionally because the creator of the PDF saved the file with default magnification settings embedded in the document's metadata.

Will updating my PDF app delete my downloaded files?

No, updating an app through the official Google Play Store or Apple App Store only replaces the application files. Your personal documents and downloaded PDF files will remain safely stored on your device.

How can I manually adjust the zoom level while reading a PDF?

You can manually adjust the zoom by using a pinch-to-zoom gesture. Place two fingers on your screen and pinch them together to zoom out, or spread them apart to zoom in.

What should I do if the 'Update' button isn't available in the app store?

If there is no 'Update' button, it means your device already has the latest available version installed. Try clearing the app cache via your device's Settings > Apps > Adobe Acrobat > Storage > Clear Cache, then restart the application.
