Separating odd from even pages is the standard remedy for a single-sided scanner. Feed the stack once and you have all the fronts; flip it and feed it again and you have all the backs, usually in reverse. Being able to pull out just the odd or just the even pages is what lets you rebuild the document properly.
It is also how you print double-sided on a printer that cannot do it automatically: extract the odd pages, print them, put the paper back in the tray, then extract and print the even ones.
Pages are copied with pdf-lib rather than re-rendered, so both halves come out identical in quality to the source document.
The extraction runs in your browser. Neither the source document nor the extracted half is uploaded.
-edited suffix. Run the tool again with the other option to get the remaining half.If your document has an odd number of pages, the last sheet has nothing on its back, which is normal. If the second pass comes out upside down, use Rotate PDF to turn the even-page file 180 degrees before printing it.
No. It means the page’s position in the document — the first page is odd, the second is even, and so on — regardless of any numbering printed on the pages themselves.
Not in a single pass. Run the tool once for odd and once for even; the source document is unchanged either way.
No. Pages are copied as complete PDF objects, so text, fonts and vector graphics are preserved exactly.
Merge the odd and even files into one document, then use Reorder PDF to interleave the pages by dragging them into place. If the even half came out reversed, run Reverse PDF Pages on it first.
Yes — use Split PDF in extract mode, where you pick individual pages from a thumbnail grid.
No. The extraction is performed by pdf-lib inside your browser.
