Doclingo
Doclingo translates PDF and Office documents while keeping the original layout intact. It handles PDF, Word, PowerPoint, Excel, scanned files, and images, with bilingual side-by-side output and support for 90+ languages. No sign-up is required to start on the free tier.
The platform routes work through several large language models, including DeepSeek, ChatGPT, Gemini, Claude, and Qwen, and uses its own layout recovery algorithm to reconstruct tables, images, and complex formatting after translation. PDF PRO adds smart OCR for text embedded in images, highlight-to-translate, glossaries, and online editing for post-translation tweaks.
Researchers reading academic papers, legal teams working through contracts, and foreign trade designers translating PDF drawings are the core users. The platform also ships iOS and Android apps, a suite of PDF utilities, and an API for enterprise batch processing.
Doclingo reports ISO 27001, SOC 2, HIPAA, and GDPR compliance certifications on its homepage, and serves over 500,000 users according to site statistics.
