How Split PDF Works
ConvertUnlimited utilizes pdf-lib, a modern JavaScript library for PDF manipulation that runs natively in your browser. When you upload a document, our tool parses its internal structure locally. Based on your specified ranges (e.g., "1-3" or "5, 10"), it creates a new PDF container and copies the specific page objects into it.
Because all logic is executed on your device's CPU and RAM, your documents are never transmitted over the internet. This local-first architecture ensures 100% privacy for sensitive files like medical records, legal contracts, and personal documents.
