Frequently Asked Questions
Everything you need to know about privacy and processing.
Absolutely. Your documents never leave your device. LocalPDF processes everything using your browser’s built-in engine — no server uploads, no cloud storage, no third-party access. Once you close the tab, the data is gone.
The Textbook Splitter takes a scanned two-page spread and mathematically cuts it down the spine into two separate pages. You drag the divider to the exact center of the spread, and LocalPDF crops each page using precise coordinate math — no image re-encoding, so text stays fully selectable.
There is no hard limit enforced by LocalPDF. Since processing happens on your machine, the only constraint is your device’s available memory. Most modern laptops and phones can comfortably handle files up to 100 MB+.
No. LocalPDF is a zero-account tool. There is no sign-up, no login, and no tracking. You open the page, drop your file, and get to work.
