Merge PDF
Combine PDFs into one file, in the order you choose. Combine two or more PDFs into one file. Put them in the order you want, keep every page from each file, then preview the result and download one PDF.
What you can do
- Combine two or more PDFs into one file.
- Put the files in the order you want.
- Keep every page from each file.
How this works
Merge PDF files without uploading them. The pages are copied into one new file, in the order of the list.
Each page keeps its own size and turn. An A4 page next to a US Letter page stays that way, and a landscape page stays landscape.
This page leaves the file size alone. Merge PDFs for email joins the files the same way, then shrinks the photos inside so the result is easier to attach.
Limits
- Add 2 to 20 files.
- Each file up to 50 MB.
- Up to 100 pages.
Common Questions
Does this change my original PDFs?
No. You download a new file. The PDFs you chose stay where they were.
Can I merge PDFs without uploading them?
Yes. The merge runs in this browser, on your device. The PDFs are not sent to a server, so a contract or a scanned ID never leaves your computer or phone.
Is it free? Do I need an account?
It is free, with no account and no sign-up. The merged PDF has no watermark and no added pages.
Does merging lower the quality?
No. The pages are copied as they are. Text stays sharp and selectable, and pictures are not saved again. The merged file is about as large as the PDFs put together. To make it smaller for an attachment, use Merge PDFs for email.
What if I add the files in the wrong order?
Drag a file into place, or use the arrows, then merge. Nothing is downloaded until you do.
Is there a size or page limit?
Yes. Two to twenty PDFs, each up to 50 MB. The result can have up to 100 pages.
Are bookmarks kept?
No. Every page, with its text and pictures, is kept. The bookmark list from the original files is not carried into the merged PDF.
Can I merge PDFs on my phone?
Yes, in a current mobile browser. Use the arrows to set the order. Large files take longer on a phone, because the work happens on the phone itself.
What if a PDF is password protected?
A Password field appears when any PDF you added is locked, and the page says so. That one password is used for every locked file. Enter the password you already know. This tool will not guess it.
What if the PDFs use different passwords?
The merge stops and nothing is downloaded. One password cannot open files that were locked with different passwords.
Is the merged PDF still password protected?
No. The password is used only to open the files you added. The PDF you download opens without a password, and that password is not saved.
Is my PDF secure?
Yes. The files stay in this browser and are not uploaded. A password is used only to open a locked PDF, and it is not saved.
