About

AI PDF Translate

Features

Translating a PDF used to mean copying text into a browser tab, losing all formatting in the process, then manually fixing terms the translator got wrong. This app handles the whole document at once โ€” keeping the layout as close to the original as possible โ€” so what you get back is actually readable. TRANSLATION ENGINES Free users get Google Translate and Bing. Paid plans unlock GPT-4o, Gemini 2.5 Flash, DeepSeek, and Doubao. For academic papers and technical documentation, DeepSeek and GPT-4o handle domain-specific terminology more accurately. For quick turnarounds on everyday documents, Google is plenty. You choose the engine; you're not locked into one. BILINGUAL MODE When turned on, the original text and translation appear on alternating pages in the same file. Useful for cross-referencing the source, or for anyone studying a foreign language alongside a translation. BACKGROUND PROCESSING Translation runs on the server. Once you submit a file, you can close the app and do something else. You'll get a push notification when it's ready to download โ€” no need to keep the screen on or wait around. WHAT IT HANDLES Academic papers, patent filings, technical manuals, financial reports, legal contracts โ€” if it's a PDF, you can submit it for translation. PLANS ยท Free: A monthly page allowance that resets each month, Google Translate only ยท Basic: 150 pages/month, all engines ยท Pro: 500 pages/month, all engines, priority queue ยท Credits: No subscription required โ€” buy a block of pages and use them whenever Subscriptions are billed through Apple and can be cancelled at any time in your device settings.
