Translate text, PDFs, Word documents, images, and subtitles without uploading your content, and keep using it offline once the neural model is cached. ## 定价与套餐 Free: no account, subscription, or daily quota. Text translation is limited to 5,000 characters per request. Offline use requires the neural model and page resources to stay cached, and clearing site data removes the downloaded models. ## 关键功能与能力 - **Free text translation:** Type or paste text and translate it instantly in your browser, with automatic language detection, up to 5,000 characters per request and no daily quota. - **Document & e-book translation:** Translate EPUB, PDF, Word, PowerPoint, and Excel files while keeping chapters, layout, and formatting intact. - **Image & OCR translation:** Read text from images and scanned PDFs with on-device OCR and draw the translation back onto the picture. - **Subtitle & speech translation:** Transcribe audio and video with Whisper in the browser and produce bilingual SRT or VTT subtitles that preserve timestamps. - **Private, on-device engine:** AI processing happens locally with open-source Opus-MT neural models, so your content never leaves your device and works offline once cached. ## 主要用例 - **Translate confidential text (Freelancer):** A freelancer translates a client contract without uploading it to a third-party cloud service, keeping sensitive terms on their own device. - **Translate an e-book or PDF (Student or reader):** A reader translates a whole EPUB or PDF chapter by chapter while keeping layout, paragraphs, and reading order intact. - **Translate signs and photos offline (Traveler):** A traveler translates signs, menus, and scanned documents from photos using on-device OCR, and caches the model for offline trips. - **Generate bilingual subtitles (Content creator):** A creator transcribes a video with Whisper and exports bilingual SRT or VTT subtitles with timestamps preserved. ## 优势 - Completely free with no account, quota, or subscription - Strong privacy: translation runs on-device with no content uploads - Covers text, documents, images, subtitles, and speech in one tool - Works offline after the language model is cached ## 局限 - Text translation is capped at 5,000 characters per request, so long articles must be split - First use on an older or low-memory device is slow while the model downloads and compiles - Translation between two non-English languages routes through English, which can soften nuance - Quality is a step below large cloud models for subtle, high-stakes writing ## 常见问题 ### What happened to Multilingual.top?
