Merge PDF
Combine multiple PDF files into one in your browser, in any order. Private — nothing uploaded.
About this tool
This tool combines several PDF files into one, in the order you choose — handy for stitching together scanned pages, bundling documents for an application, or joining chapters into a single file. It runs entirely in your browser, so your documents are never uploaded.
When you'd merge PDFs
- Combining separately scanned pages into one document.
- Bundling a CV, cover letter, and certificates for a job application.
- Joining receipts or invoices into a single file for records.
How to merge PDFs
Select two or more PDF files. They're listed in order and joined exactly that way, so choose them in the sequence you want the pages to appear. Click merge and the combined PDF downloads. All pages from each file are kept.
Because the merge happens locally with an in-browser PDF library, sensitive documents never leave your device. Note that password-protected or encrypted PDFs need to be unlocked first. To turn images into a PDF instead, use Image to PDF.
Frequently asked questions
How do I merge PDF files?
Select two or more PDFs. They are combined in the order listed, and the merged file downloads — all in your browser.
Are my PDFs uploaded to a server?
No. The merge happens entirely in your browser using an in-browser PDF library, so your documents never leave your device.
In what order are the PDFs combined?
In the order they appear in the list after you select them. Choose the files in the sequence you want the pages to follow.
Is there a limit on the number or size of files?
There is no fixed limit, but very large files depend on your device's memory since everything is processed locally.
Why won't my PDF merge?
Password-protected or encrypted PDFs cannot be merged until they are unlocked. Make sure each file is a standard, unlocked PDF.
