Merge, Split or Extract PDF Pages: Pick the Right Operation
The right PDF operation depends on how many inputs and outputs you need, and whether you want to keep, remove or rearrange pages.
Merge combines several documents
Merge PDF appends the pages of multiple inputs into one output. Our sample A has A1 and A2; sample B has B1, B2 and B3. Merging A followed by B should produce five pages in that sequence. Merging does not automatically compress image content or remove repeated pages.
Split makes separate output files
Use Split PDF when one document needs to become several files. Choose one file per page, or define groups such as 1–2 and 3–5. Page positions are the numbers shown in the preview, which can differ from page numbers printed inside the document. Overlapping groups intentionally repeat a source page across outputs.
Extract keeps a selected set together
Extract PDF Pages produces one new document from selected pages in their source order. For example, selecting B1 and B3 keeps those two pages together. Use Reorder PDF Pages if you then need B3 before B1. Delete PDF Pages takes the opposite approach: select unwanted pages and retain the remainder.
Verify the document beyond its page count
Open the download in a PDF viewer and check the sequence and appearance. Keep signed originals: modifying a document can invalidate signatures. Interactive forms, bookmarks and attachments are not guaranteed to carry over. Removing pages is not a verified redaction method for confidential data.
