About extract even pages
Even pages correspond to the reverse sides when the file starts on a front side and contains each side in order, with none missing. Isolating them answers a different question from isolating the fronts: instead of “give me the content”, it is usually “show me what is on the backs”. Auditing a scanned batch for stray handwriting, initials or terms printed only on reverse sides means looking at the even pages as a set, which is far quicker than paging through the full document. The other common use is the second pass of a manual duplex print, where this document goes through the printer after the odd pages. The selection is made against physical page positions and the chosen page objects are copied into a new document with their fonts and images intact. If the original page count is odd, this extract is one page shorter than the odd-page extract, since there is no even counterpart to the final page in the file. A one-page PDF has no even pages to extract and produces an error rather than an empty document.
How to extract even pages
- 01
Open the scanned PDF
Drop in the document whose reverse sides you want isolated.
- 02
Extract the evens
Press the action button; pages 2, 4, 6 and onward are collected automatically.
- 03
Review or print
Download the result to audit the backs, or send it through the printer as the second duplex pass.
What this tool does
- One action selects all even-positioned pages; these are the reverse sides only when the scan starts on a front and has no missing sides
- Fast way to audit a scan batch for content hiding on the backs
- Relative order preserved, so evens still line up with their fronts
- Lossless copying — nothing is re-compressed for the review copy
Limitations worth knowing
Every PDF tool has constraints. Stating them plainly is more useful than discovering them halfway through your work.
- Parity is based on physical page positions, so one missing page in the scan swaps fronts and backs from that point on.
- With an odd page count, the final page has no even counterpart in the file, so this extract is one page shorter. A one-page PDF has no even pages and produces an error rather than an empty output.
- Genuinely blank backs are still pages and will appear in the output; delete them afterwards if you want only pages with content.
How your file is handled
This tool runs entirely inside this browser tab. When you choose a file, your browser reads it from your own disk and hands the bytes to JavaScript running on this page — no network request carries your document anywhere. You can confirm that yourself: open your browser’s developer tools, switch to the Network panel, and run the tool. You will see no upload.
Nothing is stored after the fact. Closing or reloading this tab discards the file, the result and everything derived from them, because none of it ever left your machine. Read how local processing works.
Questions about extract even pages
Why does my even extract have one page fewer than the odd one?
Because the source has an odd page count. The final page is odd and has no even counterpart, so the even set is one shorter — this is expected, not a truncated result.
Can I use this to check whether the backs of a scan are blank?
Yes, that is one of its best uses. Reviewing a short even-page document is far faster than scrolling a long scan, and it surfaces handwriting or terms printed only on reverse sides.
How do I remove the blank backs entirely?
Extract the evens to see which are blank, then run Delete PDF Pages on the original using the original page positions, not the extract's renumbered positions. Page 1 of the even extract is original page 2, page 2 is original page 4, and so on: multiply the extract position by 2. Confirm those pages in the original before deleting them.
