Drop PDFs to merge
PDF files only
How It Works
Drag and drop multiple PDF files, reorder them visually, and merge them into a single document — all processed locally in your browser using the pdf-lib library. Your PDFs never touch a server.
The tool reads each PDF's internal structure, preserves all pages, bookmarks, and formatting, then combines them into one continuous document. You can rearrange the order by dragging files before merging.
