Image translation
Upload or drop an image. Choose Tencent OCR to recognize text and coordinates, then translate with a text model. Edit and export the image. PNG, JPEG and WebP, up to 20 MB; Tencent OCR inputs are converted or compressed automatically.
The vision model recognizes text and coordinates; text uses the homepage text translation service.
Enable a model that supports image input under Model settings → Image / vision models in the admin console.

Free document translation: what is included
Bilin Translate translates PDF and Word files online with bilingual previews and downloads. Guests can start without registering. Free models use no translation credits; other models use the allowance shown in the interface.
- PDF and Word
- Translate PDFs with readable text, DOCX and DOC files while retaining the layout where possible. Check complex tables, equations and page breaks.
- Free models and allowances
- Free models have no daily platform credit limit. File size, concurrency and service availability still have limits; check the current interface.
- Images and scans
- Image translation can recognize text in images. This does not mean that every scanned PDF supports direct OCR translation; check the scanned-document guide first.
