Extracting pages from a PDF means selecting a subset of pages and creating a new document with only those selected. It is useful for isolating chapters, separating sections of a report, or creating excerpts from long documents.
OnlinePdfEditor lets you select pages individually or by range, displaying thumbnail previews of each page to make selection easier. It supports non-contiguous ranges written as comma-separated lists: you can extract pages 1-3, 7, and 12-15 in one operation by typing '1-3,7,12-15'. The new PDF contains only the selected pages in the order they appear in the original document.
The technical difference from related tools is precise: 'Extract Pages' creates a new PDF with the chosen pages leaving the original unchanged; 'Delete Pages' creates a new PDF with everything except the indicated pages; 'Split PDF' separates the document into multiple files by range. If you also want to change the page order in the final result, use 'Organize PDF' which allows drag-and-drop in addition to selection. All these tools operate in the browser without uploading the file to a server.
