How to extract selected pages from a PDF

Use workspace positions rather than printed labels

A PDF can have an unnumbered cover, Roman-numbered introduction, or scanned labels that do not match its page positions. The split workspace counts pages from the beginning of the file, starting at 1.

For example, if a file begins with a cover followed by printed pages 1 through 10, the page labelled 4 is position 5 in the PDF. Open the thumbnail or page preview and verify the content instead of relying on the printed label alone.

Scroll sideways to compare all columns.

Choose ranges around the information you need

Use the range controls available in the workspace to select the required pages. Check the first and last page of each range, especially where a chapter, appendix, or supporting document begins.

An extraction creates a new output; it does not remove those pages from the original file on your device. Keep that source if you may need additional pages later. If you are building a new document from several sources, extract the relevant parts separately and use Merge PDF to assemble them in a deliberate order.

Check content as well as page count

A file with the right number of pages can still contain the wrong section. Inspect a recognizable heading on the first and last exported pages. Check tables or explanations that continue across a page boundary so you do not separate a chart from its legend or omit the start of a paragraph.

Selected pages may still contain information you do not intend to share. Extraction selects whole pages; it is not a redaction tool and does not remove individual names, images, or hidden information from those pages. Review the output itself before sending it.

Treat large documents as a resource-intensive task

Local processing avoids sending the PDF to a conversion server, but reading and rebuilding pages still uses device resources. The upload area’s current device limit is the relevant input constraint. A capable desktop is a better choice for a demanding document than several simultaneous mobile-browser tasks.

If the result is still too large for the destination, check whether compression is appropriate for the selected content. Splitting alone does not guarantee a particular output size because individual pages can contain large shared resources or detailed images.
