AI services differ in upload size, page-count and practical browser constraints. Before splitting, use the AI PDF fit checker to inspect your file locally, then separate official provider rules from Split2AI guidance on the AI upload limits page. If device memory is your concern, the benchmark page documents observed results and their limitations.
Split2AI performs PDF splitting in your browser and does not send PDF contents, filenames or page text to a server for splitting. See the methodology for how guidance is verified, related tools for other workflow helpers, and About Split2AI for the product's scope and design principles.
