About PDF Merging & Splitting

PDF merging combines multiple PDF files into a single document, preserving the original formatting and content of each file. PDF splitting extracts specific pages from a larger PDF, which is useful for sending only relevant pages or breaking up large documents. This tool uses the pdf-lib library to process PDFs entirely in your browser — your files are never uploaded to any server. You can merge as many PDFs as you need, drag to reorder them, and download the result instantly.
