Frequently asked questions
How do I merge PDF files for free?
Select two or more PDFs above (or drag them in), then click “Merge PDFs”. The combined file downloads instantly, with no sign-up, no watermark and no email required.
Can I change the order of the merged PDFs?
Yes. Files are merged in the order you add them, so pick or drag them in the sequence you want them to appear in the final document.
Are my PDF files uploaded to a server?
No. Merging happens entirely in your browser using JavaScript, so your files never leave your device, ideal for private or confidential documents.
Is there a file size or count limit?
There is no fixed limit, but very large files depend on your device’s available memory. On most computers you can comfortably merge dozens of PDFs.
Will merging reduce the quality of my PDF?
No. Pages are copied exactly as they are, so text stays selectable and images keep their original quality.
Is it safe to merge PDFs online here?
Yes. Because nothing is uploaded, there is no risk of your documents being stored or seen by anyone else. It is completely free and private.
