One-click tool that flips the page order of your PDF so the last page becomes the first and vice versa. Perfect for fixing reverse-scanned documents, double-sided scanner output and any PDF where the pages came out the wrong way around.

Your files never leave your device.
How it works:
Processing...
Drop a PDF onto the upload zone or pick it from your device. The file is processed locally in your browser; nothing is uploaded.
ZentoPDF reads the page tree, reverses the order so page N becomes page 1, N-1 becomes page 2 and so on, and rebuilds the document accordingly.
Click download to grab a new PDF whose pages run from the original last page to the original first page. The source file stays untouched on your device.
Most often when a scanner produced pages in the wrong order: e.g. you scanned a stack face-down so the document ended up reversed, or your duplex scanner output odd pages from end to start. Reversing the PDF in one click is much faster than re-scanning everything.
Yes. The whole document is reversed as a single sequence. If you only need to reverse part of the document (e.g. pages 10–20), use our Extract Pages tool to pull those pages first, reverse the extract here, then re-merge them with Merge PDF.
Yes. ZentoPDF only changes the page order in the page tree; every page object, including its annotations and form fields, is kept intact. Bookmarks that pointed at a specific page now still point at the same page object, even though its page number has changed.
No. The whole operation runs locally in your browser using pdf-lib. Your original PDF and the reversed output never leave your device.
Yes — 100% free, no signup, no watermark, no daily quota. Reverse as many PDFs as you like, as often as you like.
