Frequently Asked Questions
Can I rotate individual pages?
Currently PDFStack applies the same rotation to all pages. Rotate, then use Organize PDF to reorder or remove pages as needed.
Does rotation reduce quality?
No. PDF rotation changes a metadata flag — pages are not re-rendered, so there's no quality loss.
Can I rotate multiple PDFs at once?
Yes — add multiple PDFs and they'll all be rotated by the same angle.
Is it private?
Yes. Everything runs in your browser.
