Merge PDF guide and tips
Files are joined from top to bottom, so check the order before you merge. You can remove a file with the cross button.
All pages are copied as they are, including their size and rotation. If you only need some pages from a file, extract them first with the Split PDF tool.
Password-protected files cannot be merged. Remove the password in the program that created the file, then add it again.
Merge PDF FAQ
How many PDFs can I merge?
There is no fixed limit. The practical limit is the memory of your device, so very large batches may need to be merged in smaller groups.
Does merging change my pages?
No. Pages are copied without changing their content, size or orientation.
Are my files uploaded to a server?
No. Everything happens inside your browser on your own device. Your PDFs and images are never sent to our servers, so your documents stay private.
Is this tool really free?
Yes. It is free to use with no sign-up, no watermark and no daily limit. The site is supported by advertising.
