Merge PDF → Single PDF (Client-side)

Choose multiple PDF files and merge them into one PDF using only HTML + JavaScript (no server required). Uses pdf-lib library.

How to use

1. Select two or more PDFs.
2. Click Merge PDFs. When finished, a merged file will be downloaded.

Notes

This runs completely in the browser. Large files may use significant memory. If you need server-side merging, ask and I’ll provide a Node.js example.
