Combine several PDF files into one — privately in your browser.
Processed locally — your files are never uploaded.
How do you merge multiple PDF files into one?
Each source PDF is loaded and all of its pages are copied, in order, into one new PDF document, with content intact. For example, merging a 3-page cover and a 2-page appendix produces a single 5-page PDF. Everything happens in your browser, so your files are never uploaded.
Understanding your result
Pages are copied with their content intact, and files are combined in the order you select them.
Formula and method
Each source PDF is loaded and all of its pages are copied, in order, into one new PDF document.
Assumptions and limitations
Password-protected (encrypted) PDFs may not merge. Remove the password first, then try again.
