Merge PDF — frequently asked questions

How many PDF files can I merge at once?
You can merge as many PDF files as your browser can hold in memory — typically dozens of documents at once. There is no fixed limit and no signup required.
Will merging reduce the quality of my PDFs?
No. Merging copies the original pages exactly, preserving text, images, fonts, and formatting. The output is identical in quality to the source files.
Can I change the order of pages after merging?
The files merge in the order you add them. To rearrange individual pages, use the Organize PDF tool after merging.
Are my files uploaded to a server?
No. Merging runs entirely in your browser using your device, so your documents are never transmitted or stored anywhere.
