About This Tool

Sometimes you need to both split and merge PDF documents as part of a larger document management workflow. While this tool focuses on the merge side of the equation, it's designed to work seamlessly with our split tool for complete PDF handling. Start by merging your base documents here, then use the split tool if you need to extract specific sections. Or work in reverse - split large documents into sections, then merge selected portions into new documents. This flexibility gives you full control over your PDF workflow, all while maintaining the privacy benefits of local browser processing.
