Frequently Asked Questions
What is splitting a page in half used for?
Two-up scans, book spreads, and side-by-side layouts often place two logical pages on one sheet. Splitting cuts them into separate, single pages for cleaner reading, printing, or reflow.
Does splitting reduce quality?
No. Each half is produced by cropping a copy of the original page, so text stays selectable and vector graphics stay sharp. Nothing is rasterized.
Can I move the fold off-center?
Yes. The fold position slider ranges from 10% to 90%, so you can split asymmetric layouts, gutters, or uneven margins wherever the seam sits.
Is my PDF uploaded anywhere?
No. Split PDF Page runs entirely in your browser using pdf-lib. For supported workflows, file contents are not uploaded for processing; site analytics and the assistant are separate.
