When merging PDFs helps
Combining PDFs can make a set of documents easier to share or keep together. For example, you might put a cover page, a report and an appendix into one file, in the order you want someone to read them.
TestiFollow’s Merge PDF tool is free and anonymous. It processes your files in your browser; they are not uploaded to TestiFollow for merging.
How to merge your PDFs
- Open the Merge PDF tool.
- Choose or drop at least two PDF files into the tool.
- Check the displayed file order. Move files up or down to arrange them, or remove a file you don’t want to include.
- Click Merge PDFs.
- Download the merged PDF to your device.
The tool copies pages in the displayed file order. After downloading, check the page order and test any links, forms or annotations you still need.
Limits and things to check
- You can combine up to 20 PDFs. Each file can be up to 25 MB, with up to 100 MB combined, and the total must be no more than 300 pages.
- Password-protected or encrypted PDFs are not supported. Remove the password first, with the document owner’s permission.
- The tool copies pages structurally rather than turning them into images, and preserves their visible dimensions and orientation. However, advanced features such as bookmarks, forms, annotations, links and metadata may not all be preserved. Check any features you need in the downloaded file.
