When this tool is useful
Merging PDFs is useful when you need to put related forms, reports or scanned documents into one file. Files that are encrypted, damaged or unusually large may need to be prepared first.
How to use it
- Choose two or more PDF files.
- Set the files in the order you want their pages to appear.
- Merge the documents and review the page sequence in the downloaded PDF.
Common uses
- Combining report sections into one file
- Putting forms and supporting documents together
- Preparing a single PDF for email or upload
Select files in the order you want them to appear. If only some pages from a source document are needed, extract those pages first and then merge the resulting PDFs.
Tips for a reliable result
Select files in the final page order and check each source document for rotation or blank pages first. Keep the originals until you have reviewed the merged PDF.
Frequently asked questions
How do I combine PDF files into one?
Select the source PDFs in the order you want, run Merge PDF and download the combined document.
Will merging change my original PDF files?
No. The tool creates a new file and does not overwrite the source documents.
Can I merge password-protected PDFs?
Encrypted PDFs may be rejected by the browser library. Only process documents you are authorised to access, and use an unencrypted permitted copy if needed.
