What is PDF Merge & Split?

Merge multiple PDF files into a single document or split a PDF into individual pages — all directly in your browser. Upload your files, rearrange the order for merging, or select which pages to extract when splitting. The tool uses the pdf-lib library for high-fidelity PDF processing without any server uploads. Your documents stay completely private on your device.
