Merge PDF files into one

Drop two or more PDFs, drag the cards into the order you want, and download a single combined file. The work happens on your device, so nothing is uploaded.

  1. 01

    Add your PDFs

    Drop them onto the page or use Add files. Each file shows a thumbnail of its first page and its page count.

  2. 02

    Set the order

    Drag the file cards. The top card becomes the first pages of the merged document; the next card follows, and so on.

  3. 03

    Merge and download

    Press Merge & download. The pages are copied into one new PDF and saved straight to your disk.

Why merge in the browser instead of uploading

Most free “merge PDF” sites upload your files to a server, process them there and email or link the result back. For a contract, a bank statement or anything with personal data, that is a copy of your document sitting on someone else’s machine.

This tool uses pdf-lib running in your own browser tab. Open the Network tab while you merge and you will see no file leave the page. There is also no size cap beyond what your device’s memory can hold.

Keeping the page order right

The merged file follows the order of the cards top to bottom. Reorder before you press the button — there is no way to shuffle pages inside the result afterwards without splitting it again.

If you only need some pages from a file, open Split first, extract the pages you want as a new PDF, then bring that into the merge.

Bookmarks, forms and signatures

Merging copies the visible pages. Interactive form fields and digital signatures are generally not carried across — flatten a form (print to PDF) before merging if the field values matter.

Outlines and bookmarks from the source files are not preserved either; the result is a clean, flat document.

Questions

Are my PDFs uploaded to merge them?

No. Merging runs in your browser with pdf-lib. Nothing is sent to a server — you can confirm this in the Network tab.

How many PDFs can I merge at once?

There is no fixed limit. The practical ceiling is your device’s memory; a few dozen ordinary PDFs is no problem.

Can I change the page order?

Yes. Drag the file cards before merging. The top card becomes page 1 of the result.

Will form fields or signatures survive the merge?

Usually not. Interactive fields and digital signatures are dropped. Flatten the form first if the values need to stay.

Is there a watermark or a daily limit?

Neither. Every feature is free with no watermark and no cap.

Open the merge tool

It opens ready to use. No sign-up, no watermark, no page limit.
