Merge PDF: all your documents in one file
Merging PDFs puts several files one after the other into a single PDF. It comes up all the time: supporting documents for an application, test results you send to a patient, the month's invoices for your accountant.
Most PDF merge services upload your files to their servers. Here the merge happens in your browser: the documents never leave your computer or phone, so you can use it for sensitive documents too.

Before you merge your PDFs
Are my files uploaded anywhere?
No. Merging happens entirely in your browser. The files aren't sent to any server, not even ours, so you can safely merge medical, accounting or personal documents.
How do I keep only some pages of a PDF?
In the "Pages" field under each PDF, type the pages you want, separated by commas: "1-3,5" keeps pages 1, 2, 3 and 5. "4-" means from page 4 to the end. Leave it empty to include every page.
Can I add photos or scanned documents?
Yes. Each JPG or PNG photo becomes one A4 page, portrait or landscape depending on its shape, placed wherever you put it in the list. Phone photos keep the right orientation.
Why can't I merge a password-protected PDF?
PDFs with a password or protection are encrypted, and merging them would produce blank pages. Open the file with its password, choose Print → Save as PDF, and add the new file.
Does page quality change?
No. Pages are copied as they are: text stays selectable and images aren't recompressed. If a PDF has a fillable form, fill it in before merging.
Is there a file limit?
Up to 40 files of 100 MB each at a time. Because merging happens on your device, very large files on an older phone may take a while. In that case, merge them in two rounds.
