Free Online Document Translation

Doclingo’s AI translation service relies on high-performance servers, and each translation incurs computing and bandwidth costs. To sustain the free tier long-term without compromising quality, free tasks use a queuing system so every user can fairly access resources. You’ll be notified by email as soon as your task is complete — no need to stay on the page. If you’d like immediate processing, you can choose a paid plan to access the priority lane.

Doclingo's free version supports online translation of multiple file formats including PDF, Word, PPT, Excel, EPUB, SRT, and more. Translated documents support high-fidelity layout preservation and online preview. Image-based files involve OCR recognition costs, so the free version only provides a partial preview — full results require a membership upgrade.

The free version supports the same language range as the paid version, covering 90+ languages including English, Chinese, Japanese, Korean, French, German, Spanish, and more. Language options are not restricted for free users.

Yes. Doclingo can perform OCR (Optical Character Recognition) on scanned PDFs before translating, but the free version only provides a partial preview. To view the full translated results, you can register an account and use the complimentary member credits to experience the full OCR translation in member translation for free. The translation quality of scanned documents depends on the original scan clarity — the higher the clarity, the higher the recognition and translation accuracy.

To protect user privacy, files uploaded by free users are automatically deleted within 7 days after translation is complete. Member users' files are retained for 3 months. We recommend downloading your translations promptly within the retention period.
