About This Tool
Split PDF is a free-to-use online PDF split tool that requires no installation and no registration — just open and use. It splits a single PDF into multiple independent PDF files by custom page ranges or a fixed page count, with support for multiple flexible intervals. All processing happens locally in your browser, so your files are 100% private and never uploaded to any server. Whether you are splitting chapters, extracting key pages, or reusing content, this tool has you covered — upload and split with results rivaling professional PDF editors. (Note: "free" refers to daily free quota, not unlimited; for high-volume or professional needs, consider the membership plan for more quota.)
