Folio

Folio is a free AI-powered PDF toolkit for iPhone. Scan documents into searchable PDFs with OCR, convert files to Word, Excel, PowerPoint or JPG, and merge, split, compress, rotate or reorder pages in seconds. Sign documents, fill forms, add annotations and protect files with passwords. Folio's built-in AI summarizes long documents, answers questions about any file, and extracts structured data such as tables, invoice totals and key dates. Everything runs in a fast, privacy-friendly native iOS app with Files and iCloud integration, so you can go from scan to finished, shareable PDF without leaving your phone. Built for students, freelancers and professionals who handle paperwork on the go.
