Turn any PDF — or web article — into audio you'll actually listen to. PDF2Audio reads your PDFs aloud with natural AI voices — word for word, or as a lecture or a two-host podcast. Books get their own chapters, so a whole book plays like an audiobook. Paste a link, or share a page from Safari, and listen to the article instead of reading it. WHY PEOPLE USE IT • Read aloud: every word of your PDF, narrated clearly. • Book mode: whole books, with chapters you can jump between. • Lecture and podcast styles that explain the material. • Web articles: paste a link or share from Safari — the article, not the menus and ads around it. • Starts playing in about a minute — listen while the rest is made. • Mini player: audio keeps playing while you move around the app. • Continue listening: pick up where you stopped, right from the Library. • Quiz, key terms and section summaries to help you study. • Read along with the full transcript. • Sleep timer, adjustable speed, and your place saved — on iPhone and on the web. • Page range: convert just the pages you need. • Scanned PDFs work too — text recognition runs on your device. • 13 voices, 18 languages. • Library, playlists and downloads for offline listening. FREE TO START Your first 50,000 characters are free. When you need more, subscribe for a monthly allowance or buy credits once — they never expire. Subscriptions renew automatically until cancelled in iOS Settings. PRIVACY Your PDFs and links are used only to create your audio and are never sold or used for ads. No ads, no tracking.
