Putting several PDFs into one file is useful for application packs, invoices and meeting notes. The important part is deciding the reading order before combining anything. A successful merge should preserve the pages you need and make the final document easier to follow.
Step-by-step instructions
- Create a working folder and keep the source PDFs unchanged. Give each file a recognisable name rather than relying on a download number.
- Open Merge PDF and choose the documents. Check that none is password protected and that the combined selection fits the stated file limits.
- Use the file-order controls to put the cover or introduction first. Every selected document contributes all of its pages.
- Prepare the PDF and wait until the download link appears. Keep the tab open while the operation runs.
- Open the download in a PDF viewer. Check the boundary between each source document, the total page count and the final filename.
A practical example
For a job application, arrange a cover letter, CV and certificates in that order. If they contain one, two and four pages, the combined result should contain seven pages. Remove unnecessary blank pages from a working copy before merging if the recipient has a page limit.
Common mistakes and limits
Merging is not compression. A larger final file is not necessarily an error, and the tool does not optimise every embedded photograph. Digitally signed files, forms and complex navigation require careful checking after any PDF rewrite.
Frequently asked question
Can I combine only a few pages from each file?
Extract those pages with Split PDF first, then merge the extracted copies. Do not assume that selecting a file selects only the page currently visible in your PDF viewer.
