Frequently asked questions
Is this PDF Merge tool free to use?
Yes, it is completely free with no sign-up or usage limits.
Are my PDFs uploaded to a server?
No. Merging happens entirely in your browser using JavaScript — your files are never uploaded anywhere.
Can I control the order of the merged pages?
Yes, use the ↑ and ↓ buttons next to each file to reorder them before merging. The final PDF follows the order shown in the list.
Is there a limit on file size or number of files?
You can merge up to 20 files at a time, with a combined size limit of 50MB, to keep the browser tab responsive.
Will merging affect the quality of my PDFs?
No. Pages are copied directly from the source files, not re-rendered or re-compressed, so content quality is preserved exactly.
