LiveMerge PDFs
Combine multiple PDFs into a single file.

Frequently asked questions
Are my PDFs uploaded anywhere?
No. The PDFs are merged in your browser via pdf-lib. No server, no log, no intermediate step. Close the tab and the source files are gone, only the merged result stays in your Downloads.
How many PDFs can I merge at once?
No artificial limit from Plainjar. In practice, 20-50 normal PDFs work smoothly; many tens of MB total can get slow on weaker devices since everything runs in browser memory.
Does this work with password-protected PDFs?
No, encrypted PDFs throw an error. Remove the password first (with the 'Remove PDF password' tool coming soon, or in the originating application). Then they can be merged here.
Do bookmarks, links and form fields survive?
Pages and in-page hyperlinks keep working. PDF bookmarks (the table-of-contents structure) are lost. Form fields stay structurally but can collide if multiple PDFs use the same field ID, review after merging if forms matter.
