How is this different from other online PDF tools?

Most online PDF tools send your files to a remote server for processing. This tool processes everything locally in your browser using client-side JavaScript. Your files are never transmitted to any server, which means your document content stays entirely under your control.

Are my PDF files uploaded?

No. Your files are read directly by your browser. Your files are never transmitted over the network. The tool works entirely within the browser tab you have open.

Can I verify that files are not uploaded?

Yes. Open your browser's developer tools (F12), go to the Network tab, and watch for any outgoing requests while using the tool. You will see no file data leave your browser. The site may record an anonymous page-view count, which never includes your files and can be disabled.

Does this tool work offline?

Yes, once the page has loaded the tool processes your files entirely in your browser; tool functionality needs no network connection. You can disconnect from the internet and continue using it.

What happens when I refresh the page?

Because nothing is stored on a server, refreshing the page clears your current session. Any files you had selected will need to be selected again.

Does this tool store my files?

No. Files are held in browser memory only for as long as the page is open. Closing or refreshing the page discards them. Nothing is written to disk by the tool, and nothing is sent to a server.

Can this tool unlock password-protected PDFs?

No. This tool does not attempt to remove or bypass PDF password protection. If you know the password, the Unlock PDF tool on this site can remove it locally; then this tool can process the file.

What technologies does this tool use?

This tool uses client-side JavaScript and pdf-lib to copy the odd- or even-numbered pages into a fresh PDF entirely within your browser — your files never leave your browser.

Does this tool use WebAssembly?

No. This tool uses client-side JavaScript and pdf-lib for local PDF structure editing. No WebAssembly is involved.

How do I extract just the odd or even pages?

Pick one PDF from your device with the file picker, choose "Keep odd" or "Keep even", then select Extract. A new PDF with the matching pages is built in your browser and offered as a download named odd-pages.pdf or even-pages.pdf.

Does odd/even count from the printed page numbers on each page?

No. It counts the document's actual page order starting at 1, so the first page is odd, the second is even, and so on. If your PDF's printed labels start somewhere other than 1, the parity here may not match those labels.

Why is this useful for double-sided printing on a one-sided printer?

Extract the odd pages and print them, then flip the stack and print the even pages onto the blank sides. Because the tool preserves the document's 1-based page order within each set, the sheets line up for manual duplex printing.

Does the Extract Odd / Even Pages tool cost anything to use?

Extracting odd or even pages is completely free — no account, no sign-up, and no cap on how many PDFs you run through it, and it always will be. Every step happens inside your own browser: your PDF is read into local memory, pdf-lib copies the matching pages into a new document, and the result is handed straight back to you as a download — no file data is ever sent to a server or any external service.
