What this tool does
Combines several PDFs into one. The order of the files you select becomes the page order of the result, so numbering file names makes ordering easier.
How to use it
- Select all the PDFs at once.
- Check that the file name order matches the page order you want.
- Run it to produce a single merged PDF.
- Open the download and verify page count and order.
Worked example
Running it on a single three-page PDF returns three pages. A three-page file plus a two-page file gives a five-page PDF.
Frequently asked questions
- I want a different order.
- Prefix file names with 01_, 02_ and select them again. To reorder after merging, use the reorder PDF pages tool.
- Are bookmarks and form fields preserved?
- Page content is copied, but document-level bookmarks and form structures are not guaranteed to survive. Check the merged file yourself.
What this tool does not cover
Files are processed in your browser and not uploaded. Unlock password-protected PDFs first, and keep a copy of your originals before merging.
