腾讯翻译君

Tencent Fanyi Jun (also known as Tencent Translator or 翻译君) is a machine translation service developed by Tencent, primarily designed to facilitate cross-language communication for individual users and professional scenarios. The platform offers three main translation modes: text translation, image translation, and document translation. For text translation, users can input up to 2000 characters per request, with automatic language detection that identifies the source language from a list including Simplified Chinese, English, Japanese, Korean, French, Spanish, Portuguese, German, Italian, Russian, Arabic, Thai, Vietnamese, Indonesian, Malay, Hindi, and more. The system then provides a translated output in the target language selected by the user. The auto-detect feature reduces the need for manual language selection, making the process smoother for casual users who may not know the origin language. Image translation allows users to upload pictures containing text—such as screenshots, photographed signs, menus, or documents—and the service extracts the embedded text using optical character recognition (OCR) before translating it. This is particularly useful for travelers reading foreign street signs, restaurant menus, or product labels without needing to manually type each word. The document translation feature supports uploading files in common formats (such as PDF, Word, Excel, PowerPoint, and text files) and returns a translated version while preserving the original layout as much as possible. This is beneficial for business users who need to quickly digest foreign-language reports, contracts, or presentations without switching between tools. The service is accessible via a web interface and also offers API endpoints for developers to integrate translation capabiliti
