PDF Merge & Split
Merge multiple PDF files into a single document, or split one PDF into separate pages/ranges.
Processed entirely in your browser — your files are never uploaded to a server.
Drag & drop PDF files here, or click to browse
Add two or more PDFs — they'll be combined in order
How it works
- Your PDF files load directly into your browser using the pdf-lib library — nothing is sent anywhere.
- To merge, each source PDF's pages are copied in order and appended onto a new, empty PDF document.
- To split, the page range you choose is copied out of the original into a new PDF, leaving the source file untouched.
- The result is assembled and handed straight to your browser as a download — no upload, no waiting on a server.
