How to Extract All Odd or Even Pages From a PDF
Updated 2026-07-10
To extract all odd or even pages from a PDF, open the PDF Split & Extract tool, tap Odd (or Even) in the quick-select bar to instantly highlight every matching page, then choose Extract selected pages to save them as one PDF. It runs entirely in your browser — your file is never uploaded — so even confidential scans stay on your device.
Why you'd want only the odd or even pages
The most common reason is a double-sided document scanned on a single-sided (simplex) scanner. Since the scanner can only capture one face at a time, people scan the whole stack face-up to get the fronts, then flip the stack and scan again for the backs. You end up with a PDF where all the odd-numbered pages are the fronts and the even-numbered pages are the backs (or vice versa) — jumbled together in one file.
Other real cases where odd/even extraction helps:
- Print layout prep — pulling only odd pages so they land on right-hand (recto) sheets in a booklet.
- Removing blank backs — many duplex-scanned documents have empty even pages; grabbing just the odds drops the blanks.
- Separating a two-up handout where fronts and backs are different content types.
Whatever the reason, the method is the same, and the PDF Split & Extract tool handles it without a page limit, watermark, or account.
Step by step: pull out every odd (or even) page
- Open the PDF Split tool and drop your PDF onto the page. A thumbnail of every page appears so you can see exactly what you are selecting.
- In the quick-select helpers, tap Odd to select pages 1, 3, 5, 7… or Even for pages 2, 4, 6, 8… The matching thumbnails highlight immediately.
- Confirm the selection visually. If you need the opposite set, tap Invert to flip odds and evens in one click.
- Choose your output. Save one combined PDF keeps all the selected pages together in a single file — this is what you want for separating fronts from backs.
- Click extract and the new PDF downloads. Optionally enable strip metadata first to remove author, creation-date, and software tags from the result.
That is the entire process. Because everything is computed locally, extraction is essentially instant even on large documents.
Reassembling a double-sided scan (interleaving fronts and backs)
Extracting odds and evens is usually step one; the goal is often to rebuild the document in correct reading order. Here is the classic workflow:
- Extract the fronts (the odd pages) into one PDF using Odd.
- Extract the backs into a second PDF using Even. Note the ordering: when you flip a stack and re-scan, the backs frequently come out in reverse order. If your scanner did this, your even pages run last-to-first.
- Interleave the two files so pages alternate front, back, front, back. Send both PDFs to the PDF Merge tool, where you can order and combine them into a single, correctly sequenced document.
If your backs were scanned in reverse, extract them and reverse that half before merging so page 2 lines up with page 1. A quick visual check of the thumbnails after merging confirms fronts and backs are paired correctly.
More ways to use Odd/Even and the other quick-selects
The All / None / Odd / Even / Invert helpers are designed to make bulk selection painless:
- All then Invert after tapping a few pages lets you select everything except those pages.
- Combine a quick-select with manual taps — start from Even, then tap to add or remove a stray page.
- Prefer typing? Use the page ranges field with values like 1-3, 5, 8-10 instead of the quick buttons.
- Need one file per page instead? Choose a separate PDF per page, delivered as a .zip.
If your real goal is to drop pages rather than keep them, use Remove / delete selected pages — tap Even, then delete, to strip out every blank back and keep only the fronts.
Tips, edge cases, and privacy
- Odd/Even counts document pages, not printed page numbers. Selection follows the physical page order in the file, so a cover page shifts what counts as odd.
- Large or scanned PDFs work fine; image-heavy files just take a moment longer to render thumbnails.
- No signup, no watermark, no page cap — split a 2-page or a 2,000-page file the same way.
- Nothing is uploaded. The PDF Split & Extract tool processes your document entirely in the browser, so sensitive contracts, medical records, or ID scans never leave your computer. When you close the tab, the file is gone — there is no server copy to worry about.
