Merge PDF Files into One Document
Add two or more PDF files, arrange them in the order you need and export one combined document. Toolistify should show the number of files, total pages, estimated output size and verified privacy behavior before the merge begins.

How to combine PDFs
- Add the PDF files.
- Review file names and page counts.
- Arrange the files or pages.

- Open the output and check that every page is present.
What may change during a merge
Depending on the library and files, interactive forms, digital signatures, bookmarks, attachments, comments, encryption and accessibility tags may not be preserved. The page should list tested behavior rather than saying that every feature remains unchanged.
Password-protected PDFs
Explain whether encrypted files are unsupported, require a password locally or are uploaded for processing. Never request or log a document password unnecessarily.
FAQs
Can I reorder individual pages?
Yes. You can reorder pages of a file containing 2 or more pages.
Will merging invalidate a digital signature?
Modifying a signed PDF can invalidate or remove signature validity.
Are files stored after merging?
Files become available for download once you are ready. Save them on your device because Toolistfy does not store them.
Can I merge very large files?
Merging small files is available for free, but for very large files a Pro plan is available.
