Frequently asked questions
How does the PDF halving tool work?
It duplicates each original spread page and crops the left and right halves with exact coordinate boundaries, outputting two sequential single pages for every spread.
Does splitting reduce text or scan quality?
No. Vector text, images, and scanned pages are preserved with zero re-compression or quality degradation.
Can I split Manga or right-to-left books?
Yes! Switch the reading order to 'Right then Left' so the right page is placed first in the sequential output.
Are my PDF files uploaded to a remote server?
No. The entire process runs locally on your computer inside browser memory.
