Merge PDF
Advanced PDF & Document ManagementCombine multiple PDFs into one, in any order, entirely in your browser.
What is Merge PDF?
Merge PDF combines two or more PDFs into a single document in whatever order you choose. Add your files, drag them into place or nudge them up and down, then merge — all in your browser with pdf-lib, so nothing is ever uploaded. Page counts and total size are shown as you build the list.
How to use Merge PDF
Add two or more PDFs
Drop your files onto the drop zone or click to browse. Each one appears in a list with its page count and size; unreadable or encrypted files are flagged so you can remove them.
Put them in order
Drag a file by its handle to reposition it, or use the up and down arrows. The numbered badges show the exact order the pages will appear in the merged file.
Add more or remove files
Use the smaller drop zone at the bottom of the list to add more PDFs at any time, and click the X on any file to take it out of the merge.
Merge and download
Once at least two valid PDFs are listed, click Merge. The combined PDF is assembled in memory and downloads as merged.pdf — no upload, no watermark.
