O.Translator

O.Translator is an online document translation service that translates files such as PDF, Word, PowerPoint, Excel, and EPUB into 100+ languages while preserving layout. Users upload a document, choose a target language and translation mode, review a partial preview and task quote, then confirm to translate the full document and download the result. The site states OCR can read scanned PDFs and images, supports files up to 1GB, offers a glossary for terminology, online editing of translations, and team sharing of projects and glossaries. It also offers related tools for academic paper translation via arXiv links, comic (CBZ/CBR) translation, video-to-audio extraction, text translation with custom rules, and audio/video subtitle translation. Translation is billed in credits based on tokens, a document analysis fee, and the selected mode. Unpaid documents are deleted 15 days after task creation and paid documents after 30 days.
