Translate PDF
The Immersive Translate extension introduces a free PDF translation feature within the browser, allowing users to translate PDF documents while preserving their original layout. You can download either a translated-only version or a bilingual version of the PDF, with the original and translated text displayed side by side. Powered by advanced AI translation engines, Immersive Translate delivers professional-quality results in one click—whether you're translating academic papers or multilingual business contracts.

PDF PRO
Immersive Translate has also launched a PRO version of its PDF translation feature, powered by AI and specifically designed to handle the most complex PDF files. Academic papers filled with formulas and documents containing intricate tables and images have always presented challenges for PDF translation, often resulting in garbled text or disordered formats that are hard to read. The AI-driven PDF parsing technology ensures efficient and accurate parsing of these elements, allowing for the most professional translation of such documents while fully preserving formulas and charts.

Translate EPUB
Immersive Translate makes it simple to create bilingual EPUB eBooks. With one-click EPUB translation, you can quickly convert foreign-language files into cleanly formatted bilingual or single-language versions that are fully compatible with major eBook readers. Export an EPUB file from platforms like AO3, translate it using Immersive Translate, and import it directly into your Kindle or other reading devices for a seamless bilingual reading experience.

Mouse Hover Translation
Hover your mouse over any paragraph on a webpage and press a keyboard shortcut (such as Ctrl) to instantly display the translation beneath it. Immersive Translate treats each paragraph as the smallest translation unit, preserving context and making foreign-language content easier to understand and learn from.

Input Box Translation
Type text into any input field on a webpage (e.g., “Hello World”) and press the space bar three times to translate it into your target language (default is English, customizable). This feature works across common web scenarios, including search, writing, and chat. Translate instantly without leaving your current page.
