Frequently Asked Questions
Why does my PDF lag when scrolling on Android?
PDF scrolling lag can be caused by excessively large file sizes, high-resolution images within the document, outdated reader apps, or insufficient device RAM.
Does clearing the app data delete my PDFs?
No. Clearing app data removes personal settings, cached files, and login info for the reader app, but it does not delete your actual PDF files saved on your device's local storage.
How can I make heavy PDF files scroll faster?
You can compress the PDF file size using an online tool, close other background apps to free up device memory, or switch to a more lightweight PDF viewer designed for mobile performance.
