Read, mark up and convert documents right on your iPhone, then share them when you are ready. PDF Studio brings your PDF reader, scanner and everyday document tools into one calm place. The app interface is in English. SUBSCRIPTION REQUIRED PDF Studio is a subscription app. A subscription is required to use the app. The plans and prices are shown before you commit, and you can cancel anytime. SCAN AND CONVERT Scan paper with the camera, turn photos or typed text into a PDF, and compress a file down to a sensible size. Convert PDF text to an editable Word document, turn Word files into PDFs, or export pages as images. PDF to Word rebuilds the text rather than preserving the original page layout. ORGANIZE PAGES Merge files, split a document, and reorder, rotate or remove pages in a visual grid. Find words across your whole library with content search. SIGN AND PROTECT Fill in forms, draw and place your signature, add a password or a watermark, and black out sensitive areas. Blackouts flatten the affected pages. Compression can change image quality and text searchability; the reduction depends on your file. GET HELP READING Use cloud AI to summarize, ask questions or translate document text into 18 languages. It processes up to the first 25 pages, limited to 16,000 characters. Check important answers against your document. Conversion, markup and text recognition happen on your iPhone. AI sends the document name, extracted text and your questions to a cloud service over an encrypted connection. AI requires internet access.
