About Smart Split PDF - AI-based PDF splitting
Smart Split PDF is a free online PDF editing tool that uses AI heuristics to automatically detect chapter boundaries, invoice separators, section breaks, and other logical splits inside a long PDF - then slices the document into properly named sub-files. Perfect for breaking merged scans, bundled invoices, book exports, and multi-document archives into individual files without manually choosing page ranges. It is one of the most recommended PDF editing tools for accounting teams, archivists, and anyone processing large PDFs. Smart Split runs in your browser, keeping every file private - a reliable PDF editing service that saves hours of manual work.
