No limits on files or pages
Many online tools cap free merges at a few files or a few megabytes. Here there is no cap, because your own device does the work; only its memory sets the practical limit.
Private by design
Your file is processed by your own browser, in memory. It is never uploaded, stored or seen by anyone, and the page’s security policy blocks it from sending data to other servers.
Frequently asked questions
How do I merge PDF without limit?
Add two or more PDF files. Drag them into the order you want. Click Merge PDF and download the combined file.
How do I combine PDF files into one?
Add the PDFs, drag them into the order you want, then click Merge PDF. The combined file downloads straight away. You can merge two files or dozens; the order of the list is the order of the pages.
Can I change the order of the files?
Yes. Use the arrows next to each file to move it up or down before merging. To reorder individual pages after merging, use Rearrange PDF Pages.
Is there a limit on files or size?
There is no fixed limit. The only constraint is your device’s memory; a normal laptop handles hundreds of pages or files of several hundred MB.
Does merging reduce quality?
No. Pages are copied without re-encoding, so text, vector graphics and images look exactly as they did in the original files.
Is it safe to use with confidential documents?
Yes. The file is opened by your own browser and processed in your device’s memory. It is never uploaded, so no server, including ours, ever receives a copy. That makes it suitable for contracts, IDs, medical or bank documents.
