PDF Splitter

Splitting PDFs is the inverse of merging and just as common — extracting a single chapter from a textbook PDF, separating a multi-receipt batch into individual receipts, or grabbing the signature page out of a contract. Like the merger, this tool runs entirely in your browser, so confidential documents never leave your machine.

Two splitting modes cover the common cases. 'Page ranges' lets you specify which pages go into each output file with a flexible syntax (`1-3, 5, 7-9` produces three output PDFs). 'One file per page' produces one PDF per page in the input — useful when each page is a discrete document like a batched scan. Multi-file output is packaged as a ZIP for easy download. The range parser validates input carefully and reports friendly errors for out-of-bounds or reversed ranges. Uses `pdf-lib` for splitting and JSZip for packaging.
