Combine several PDF files into a single document, in the order you choose, without uploading them to any server: the merge happens in your own browser with the same library many desktop apps use. It's handy for putting a course's reading list, a month's invoices, or a report's chapters into one file.
Before merging, you can see each PDF's page count, so you can confirm nothing is missing or that you didn't upload the wrong version by mistake.
How to use
- 1Upload the PDF files you want to combine.
- 2Reorder them with the arrows or by dragging them: that will be the order of the final document.
- 3Check the page count of each file to confirm they're the right ones.
- 4Click “Merge PDF” and download the combined document.
What you can do
- Combine any number of PDFs
- Reorder files before merging

How many files you can merge
There is no fixed file limit: add as many PDFs as you need. How long the final document takes to build depends on the total file size and your device's speed, since everything runs locally.
Order matters
The final document follows the list's order, top to bottom. Use the move-up and move-down buttons (they work with the keyboard too) or drag each file into place before clicking “Merge PDF”.
Damaged or password-protected PDFs
If a file can't be read — because it's damaged or protected with a password the tool can't bypass — it's clearly flagged in the list and can't be merged until you remove it. The other valid files aren't affected.
Frequently asked questions
Are my PDFs uploaded to a server?
No. Files are read and combined in your browser; they are never sent over the internet.
Can I merge password-protected PDFs?
It depends: if the password only restricts permissions (like editing), the tool can usually still read it. If the PDF requires a password to open at all, you'll need to remove it first with whatever program set it.
Does it keep the original PDFs' quality?
Yes. Pages are copied as-is, without re-compressing text or images.
Is there a page or size limit?
The tool doesn't set a fixed limit, but very large files (above roughly 50 MB) may take longer to process depending on your device.
Can I change the order after uploading the files?
Yes, at any point before clicking “Merge PDF”, using the arrows or by dragging each file.
