How to use this PDF tool

What this tool does

Odd-positioned and even-positioned source pages are copied into two new PDFs. Reversal helps reconstruct face-up duplex scan stacks.

Odd output uses positions 1,3,5…; even output uses positions 2,4,6… with the chosen reversal applied.

Odd and even refer to positions in the selected range, not printed page labels stored inside the document.

Supported formats

Input must be a valid PDF readable by the browser libraries. Processing capacity depends on page complexity and available device memory.

FAQ

Does deinterleave odd and even pages upload my documents?

No. The selected files are read and processed by JavaScript in your browser. The page does not send the PDF contents to a processing server.

Can deinterleave odd and even pages process password-protected PDFs?

No. Remove the password with the document owner's permission before using this tool. Encrypted or damaged files may be rejected by the PDF libraries.

Will deinterleave odd and even pages preserve forms and annotations?

Basic page artwork is retained where pages are copied, but interactive forms, links, scripts, and advanced annotations may be flattened or omitted.

Why can a large PDF fail in the browser?

PDF processing uses device memory. Very long documents, complex vector pages, and high-resolution visual comparisons can exceed the memory available to the browser tab.

Which browsers work best for deinterleave odd and even pages?

A current desktop version of Chrome, Edge, Firefox, or Safari is recommended. Keep the tab open until the output download becomes available.
