Quick answer
Choose PDF merge, add documents, arrange them with Move up and Move down, then export. Merging connects whole files in list order. Use PDF page editing to remove or rearrange individual pages.
Make a material checklist first
List the main document, appendices and supporting files in the intended reading order. Prefixes such as 01, 02 and 03 make checking easier, but the actual merge follows the list inside the tool.
Open each source, record its page count and inspect orientation and blank pages. A two-page document plus a three-page appendix should produce five pages. Convert photos to PDFs first rather than simply changing their extension.
For the technical background to page copying and merging, see the official PDF-LIB features and examples. A library’s feature set is broader than a particular interface; use this guide and the actual controls to identify supported actions.
Merge and arrange the documents
- 1Open PDF tools, select PDF merge and add the files. You can try the sample PDFs first.
- 2Use Move up and Move down to arrange files. Confirm the first document contains the intended opening page.
- 3For selected pages only, extract, delete or reorder in the PDF page editor, then use the saved file in the merge.
- 4Process and download. Open the result in another PDF viewer and check total pages, document boundaries and orientation.
- 5Check file size, naming and submission limits. Inspect the resulting appearance of stamps, forms and other complex content.
Scans, encryption and signatures
- Readable scanned PDFs can usually be merged, but merging does not add searchable text or correct skew.
- Encrypted, damaged or complex files may fail. A merger is not a way to bypass document permissions.
- Rewriting or merging can affect existing digital signatures. Confirm the recipient’s accepted delivery format when signature validation matters.
- Large documents depend on available device memory. Structural PDF compression may not substantially reduce scanned-image data.
Verify the actual delivery file
Two plus three pages should equal five, but a correct count is only the first check. Inspect document boundaries for duplicates, omissions, reversed pages and incorrect order. Fix issues in the page editor and export again if needed.
This operation merges files locally in your browser. Retain source materials and the final version, inspect the result and then submit it. Use an OCR workflow separately when you need text from scans.
Common questions
Will I still be able to copy text?
That depends on the source text layer and the rewrite result. Merging scanned images does not add text recognition.
Can I merge JPG and PDF together?
Convert images to PDF first, then merge as needed. Check page dimensions and orientation.
How do I move one page?
Use PDF page editing for individual pages. Moving an item in the merge list rearranges the entire source document.
