Merge PDF
Combine several PDFs into one file, in the order you choose.
- Takes
- PDF × many
- Returns
- PDF × 1
Runs in your browser

Nothing is uploaded. The merge happens in this tab.
Sending eight attachments when one would do is the problem this solves. Drop the files in, put them in the right order, and take back a single document with every page in it.
Using Merge PDF, step by step
- 01
Drop in two or more PDFs, or pick them with the file chooser.
- 02
Drag the rows to set the order. The queue is exactly the page order you'll get.
- 03
Merge, then download the combined PDF.
What people use it for
- Send a contract and its appendices as one file.
- Combine a month of receipts or invoices for an expense claim.
- Join chapters or sections that were scanned separately.
What goes in, and where it goes
- What it accepts
- Two or more PDF files. Anything that isn't a PDF is left out of the queue, and the page tells you how many were skipped.
- What you get back
- One PDF containing every page of every file, in the queue's order.
- Where your file is processed
- Merge PDF runs in your browser. Your files are read from disk into this tab, combined here, and handed straight to your downloads — they are never uploaded, and nothing is left behind when you close the tab.
Common questions
How many PDFs can I merge at once?
As many as you like. Each file has to be under 100 MB, because the work happens inside your browser tab and a file that size would run it out of memory — but there is no limit on how many you queue up.
Can I control the page order?
Yes. Drag the rows into the order you want before merging — the queue you see is exactly the page order of the result.
Can I merge a password-protected PDF?
No. A protected file is rejected by name, and PDFBull never tries to unlock it. Remove the password in the application that created it first.
