Combine Multiple PDFs into One File
Upload two or more PDF files and this tool merges them into a single PDF, in the order you choose. Reorder the files with the up and down arrows or by dragging them before merging.
The merge happens on our server: your files are uploaded, combined into one PDF, and the resulting file is streamed back to you for download. Nothing is stored afterward.

Frequently Asked Questions
Is this Merge PDF tool free?
Yes, merging your PDF files is completely free.
Can I change the order of my files?
Yes. Use the up and down arrows next to each file, or drag them, to reorder before merging — the files are combined in that exact order.
What's the difference between "By files" and "By pages"?
"By files" lets you reorder and remove whole PDF files before merging. "By pages" shows every page as a thumbnail, so you can remove or reorder individual pages — even across different files — before merging.
Are my files kept private?
Your PDF files are uploaded to our server only for the duration of the merge, processed in memory, and discarded immediately afterward — they are not stored.
Is there a limit on the number of files?
There is no fixed limit on the number of files, but each uploaded PDF must be 50 MB or smaller.
