PaperKit › Merge PDF

Merge PDF

Combine multiple PDF files into one PDF in the order you choose, fast and free in your browser. No upload, no signup, and free to use in your browser.

How to use Merge PDF

Drop two or more PDFs.
Reorder them if you like.
Click Run — you’ll get one PDF.

Combine a report and its attachments into one PDF

Add at least two PDFs in the order you want them combined. PaperKit copies all pages from the first file, then the next, into a new document. Your source files remain unchanged and the documents are processed on your device.

Check the order before merging

For an application packet, add the cover letter first, the form second, and supporting documents last. Check the file list before running the merge and review the resulting preview. Files with different page sizes keep those sizes; merging does not resize or reformat their content.

Choose pages before combining files

Merge includes every page of every selected file. If you only need an appendix or a single statement, extract those pages first. To change the order inside the finished document, use Reorder Pages. Existing PDF bookmarks, forms, and digital signatures should be checked in the output rather than assumed to survive a merge.
