Doc2Lang is an AI-driven document translation platform that enables users to translate files across formats like Excel, Word, PDF, PowerPoint, CSV, EPUB, HTML, and IDML, as well as media files (video, audio, images, subtitles). It leverages advanced AI models (GPT) to produce context-aware, near-human translations while preserving original formatting, layouts, and embedded elements. Key features include built-in OCR for scanned documents and images, support for over 100 languages, a custom glossary for consistent terminology, free translation previews, and pay-per-use billing. The workflow is simple: upload a file, let the AI translate, preview a sample, and download the completed file after payment. Security measures include HTTPS encryption and the option to delete files from servers. Doc2Lang is suitable for businesses and individuals who need accurate, formatted translations without committing to subscriptions.
