How the PDF Merge & Split works
This tool reads and rebuilds your PDF files entirely inside your browser using an open-source PDF engine. Nothing is uploaded to a server — your documents never leave your device.
Best for
- Combining multiple PDFs into one document
- Splitting a large PDF into individual pages
- Pulling out a specific page range from a longer document
Good to know
- Password-protected or encrypted PDFs aren’t supported — remove the password first
- Very large PDFs (100+ pages or large embedded images) may take longer to process on older devices
- Scanned PDFs (image-only, no real text layer) merge and split fine, but page content itself isn’t altered or improved
Frequently asked questions
Is there a page or file size limit?
No hard limit, though very large PDFs (100+ pages or big embedded images) take longer since everything processes on your device rather than a server.
Can I merge password-protected PDFs?
Not directly — remove the password first in a PDF reader, then merge or split as normal.
Are my documents uploaded to a server?
No, the entire merge or split happens locally in your browser using an open-source PDF engine.
