How can I verify the PDF isn't uploaded?

Open your browser's DevTools (F12) and go to the Network tab, then use the tool. The only requests you will see are this site's own script files (PDF.js with its worker for the page previews, and pdf-lib), which load when the tool first needs them, and blob: entries for the page previews, which your browser holds in memory. None of them sends your PDF to our servers. All processing happens in your browser tab.

Why split a PDF without uploading?

Some files are not appropriate to send to a third-party service, and some networks block uploads altogether. Processing locally avoids both problems.

Is the quality of the extracted pages preserved?

Yes. Pages are copied from the source PDF without re-encoding. Text, images, and formatting are identical in the output.

What is the extracted file called?

It keeps your file name and adds -extracted, so report.pdf downloads as report-extracted.pdf. The new file starts with empty document properties, so the original's title, author, and dates are not carried over.

Split PDF Without Uploading

Extract pages from a PDF entirely in your browser. All processing runs in your browser, with no third-party service involved. Drop your PDF, enter the page numbers or ranges you want to keep, and download the result.

How it works

Picking a file with the file input only hands the bytes to the browser. pdf-lib parses those bytes in memory and copies the pages that match your range expression into a fresh document, leaving the other pages' content behind, and the result is offered for download. The entire workflow runs in your browser tab, and our servers are not involved at any point.

Processing runs in your browser

All processing happens inside your browser tab. pdf-lib handles everything in memory; our servers are not involved at any point. You can verify this yourself in your browser's DevTools Network tab.
