Reverse page order
Flip the document back to front.
This tool runs entirely in your browser. Your file is never uploaded, and you can verify that in your browser's network tab. Verify it yourself: open your browser's network tab and watch. You will see one small request asking whether you have tasks left - a tool name and a hash, never the file.
What this does
This turns the document back to front: the last page becomes the first and so on. Pages are copied rather than re-rendered, so it costs nothing in quality.
Almost always to fix a scanner. Document feeders that stack their output face-up produce a PDF that reads from the last page backwards, and the fix is a single pass through this tool. It is also useful for documents in right-to-left binding order that were assembled left to right.
How it works
- Drop the PDF onto this page.
- Leave the page range empty to reverse the whole document.
- To flip only part of it, give a range - those pages are reversed among themselves and everything else stays where it is.
- Press Reverse.
- The download starts on its own.
Reversing a range does something more careful than it might sound. The selected pages swap positions among themselves, and every page outside the selection stays exactly where it was. Reversing pages 3 to 6 of a ten-page document leaves pages 1, 2, 7, 8, 9 and 10 untouched. A naive implementation that lifted the range out and put it back would shuffle the surrounding pages, which is a subtle way to lose a document's structure.
If your scan is both reversed and double-sided, this tool is only half the fix. Scanning a double-sided stack on a single-sided feeder produces two files - fronts in order, backs reversed - and what you need is Alternate and mix, which interleaves them and reverses the second automatically.
Bookmarks are re-pointed at the pages' new positions, so a table of contents keeps working after the flip.
Everything happens in your browser, so a 500-page scan is reversed without a byte being uploaded.
Questions people ask
- My scanner produced the pages backwards. Is this the fix?
- If you scanned single-sided and the output reads from the last page, yes - one pass through this tool corrects it. If you scanned a double-sided stack in two passes, you have two files and you want Alternate and mix instead, which interleaves them and reverses the second for you.
- Can I reverse only part of the document?
- Yes. Give a page range and only those pages are reversed, among themselves. Everything outside the range stays in place.
- What happens to bookmarks?
- They follow their pages to the new positions, so the table of contents still works afterwards.
- Does reversing change quality or file size?
- No. Pages are copied as they are, so text stays text, scans keep their resolution, and the file size is essentially unchanged.
