How to merge PDF files for free
Need several PDFs as one document? You can combine them in your browser in seconds — drag them into the order you want and download a single file. No account, no upload, no watermark.
Just a web browser and the PDFs you want to combine. Everything is merged on your device, so your files are never uploaded to a server.
Merge PDFs in 5 steps
-
Open the Merge tool
Go to the Merge PDFs page. It's ready to accept files immediately.
-
Add your PDFs
Drag your files onto the page, or click to choose them. You can add as many as you like, and keep adding more at any time.
-
Put them in order
Drag the rows (or use the arrows) so the files line up in the order they should appear in the final document.
-
Name the output
Give the combined file a name so it's easy to find in your downloads.
-
Merge & download
Click Merge & download. The pages are copied across losslessly into one new PDF and saved to your device.
Order is exactly what you set with the drag handles. If one of the files is password-protected, unlock it when prompted — its pages are added as images so the rest of the document stays intact.
Frequently asked questions
How many PDFs can I merge at once?
There's no fixed limit — it depends on your device's memory. Combining a handful of everyday documents is instant; very large scanned files use more memory.
Does the order I add files matter?
You can reorder freely after adding them. Drag the rows into the sequence you want before merging — that's the order in the final file.
Are my files uploaded anywhere?
No. The merge happens entirely in your browser, so your documents never leave your device. See the Privacy Policy.
Can I merge on my phone?
Yes. Add PDFs from your Files app, email, or a cloud storage app, reorder with a tap, and download the combined file.
