Merge PDF
Combine PDFs in the order you want with the easiest PDF merger available.
Select PDF files to merge
Drag and drop them here
Merge PDF combines two or more PDF files into a single document. Drag files into the order you want, then download the merged PDF. Because the merge runs in your browser with pdf-lib, your files are processed on your device and are not uploaded to a server.
What you can do with the Merge PDF
No file-count limit we impose
Add as many PDFs as your browser's memory allows — there's no artificial cap like the hourly task limits some competitors apply.
Drag-to-reorder before merging
Arrange files in exactly the order you want with drag-and-drop or the up/down controls, before you combine them.
No file size limit we impose
Large PDFs are fine — processing happens on your device, not a rate-limited server.
100% private by design
Merging runs entirely in your browser using pdf-lib — your files are never uploaded anywhere.
