Frequently asked questions
Yes, completely free. No account, no page limits, no restrictions.
No. PDF.js renders thumbnails locally in your browser, and PDF-lib rebuilds the PDF locally. Your document never leaves your device.
Click and drag any page thumbnail to a new position. The grid updates live to show the new order. Click "Apply Changes" when done to generate the reordered PDF.
Not after clicking "Apply Changes" — the new PDF is rebuilt from the current page set. To undo a deletion before applying changes, reload the page and re-upload the PDF.
There's no hard limit — the tool handles as many pages as your browser memory allows. For PDFs with 100+ pages, rendering all thumbnails may take a moment on older devices.
PDF-lib copies pages exactly as-is — no re-rendering, no quality loss. Text, images, and vectors are preserved precisely from the original file.
