Split a PDF into odd and even pages

Deconstruct duplex scans into separate odd (front) and even (back) files. Reorder and realign double-sided paperwork in seconds.

Why this matters for scanned documents

Single-pass automatic document feeder (ADF) office scanners and manual flatbeds without automated duplexing force users to scan all front sides first, flip the paper stack over, and scan all reverse sides. This yields a confusing document where pages are either completely inverted or grouped together.

By splitting the file into odd and even files, you can quickly verify each side, purge blank reverse pages, and merge them back in proper numerical order. If your file only needs a specific chapter cut out, you can split by a page range instead.

How the two files are organized

The tool outputs two distinct PDF files: [name]-odd-pages.pdf (containing pages 1, 3, 5, 7...) and [name]-even-pages.pdf (containing pages 2, 4, 6, 8...). You can download either file individually or bundle both together as a ZIP.

Frequently asked questions

Manual document scanners and feeder trays without automated duplex hardware scan all front sides first, followed by all back sides. Splitting by odd and even allows you to inspect, verify, and re-collate the two page sets in proper sequence.
