Merge PDF files
Pick several PDFs at once, put them in the order you want and download them as one document.
How to use it
Select the files
Choose all the PDFs in one go from the file picker, or drag them from a folder onto the page. You can add more later.
Put them in order
Drag a file up or down the list, or use the arrows. Sort by name puts numbered files like 01-cover and 02-report straight.
Merge and download
One PDF comes down, with the pages in the order of the list. Nothing is uploaded — the merge happens in your browser.
What carries over
Text, links and fonts
Pages are copied as they are. Text stays selectable and searchable, nothing is flattened into an image and the quality does not drop.
Bookmarks, forms and signatures
The bookmark outline of the original files does not carry over, fillable form fields may stop working and digital signatures become invalid.
Common questions
Is there a limit on how many files I can merge?
No fixed limit. Everything happens in your device's memory, so a phone runs out sooner than a laptop with very large files — a few dozen ordinary documents is no problem.
Can I merge only some pages of a file?
Take the pages you need first with Split PDF, or delete the rest in Edit a PDF, then merge the results.
A file will not go into the list
It is most likely password protected or damaged. Password-protected PDFs cannot be opened here; remove the password first. The other files still go in.
Are my files uploaded?
No. The files are read in your browser and the new PDF is written there too; nothing goes over the network.
