PDF workflow guide
When to merge, split, or reorder a PDF
These operations solve different problems. Choose based on whether you need to combine documents, extract pages, or change the sequence inside one document.
Merge separate documents
Use Merge PDF when several PDFs should become one. Before adding files, decide the final order: the first file becomes the beginning of the merged document. Use the page controls to adjust the sequence, then open the result and check the first and last pages as well as a few pages at each boundary.
Merging copies pages into a new PDF. Some document-level extras, such as bookmarks or interactive form behavior, may not carry over the way they did in the source files. If those features matter, keep the originals and verify the merged file in the PDF reader your recipients will use.
Extract or divide pages
Use Split PDF to pull out a page range or create smaller documents. Page ranges are inclusive, so a range such as 2-5, 8 includes pages 2 through 5 and page 8. Check that every number is within the document's page count. For a large document, smaller ranges can be easier to review and less demanding on browser memory.
Rearrange a single document
Use the PDF Page Organizer when pages within one PDF need to be moved, rotated, duplicated, or removed. Thumbnail views help spot misplaced or sideways pages. Review the complete sequence before exporting; deleting or duplicating a page changes the page count and order.
Keep a source copy and inspect the output
Browser-based tools create a new file and do not replace your original. Save the output under a new name, open it, and confirm page count, orientation, text legibility, and any important links or form fields. For legal, financial, or archival records, compare the output with the original before relying on it.
