Read in another language. Understand more. Remember what matters. PDFex helps you translate documents and turn your content into useful study material, all in one place. TRANSLATE YOUR PDFs Translate text-based PDFs while retaining their layout where possible. Open the translated PDF in the app, then save or share it. Scanned PDFs use text recognition and produce a readable translated PDF; their original layout is not retained. TURN CONTENT INTO STUDY MATERIAL Create concise summaries, quizzes, flashcards, matching exercises, fill-in-the-blank exercises and open-ended questions. Review wrong quiz answers and return to saved study progress. START WITH THE CONTENT YOU HAVE Import a PDF or text document, paste a supported YouTube link, upload an audio file, or translate text from a photo. YouTube captions must be available; supported formats and size limits apply. KEEP YOUR RESULTS TOGETHER Search your library, filter by result type, mark favorites and rename results so you can find them again. MADE FOR EVERYDAY READING AND LEARNING Use PDFex to explore an article, review course material, understand a document or practice what you have learned. AI-generated content can contain mistakes; check important information against your source. SUBSCRIPTION AND CREDITS An active subscription is required to create results. Each plan includes a credit quota, and the app shows the estimated credit cost before you start. On renewal, credits reset to the plan quota; unused credits do not carry over. Document length, file size and page limits apply. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://www.erayjs.com/pdfex/privacy
