Document translation with AI
Doc2Lang is an AI-powered document translation service for files such as PDF, Word, PowerPoint, Excel, EPUB, HTML, IDML, subtitles, images, video, and audio. The product focuses on translating content with context in mind while preserving the original layout, formatting, and structure where possible.
The workflow is built around uploading a file, previewing part of the translation for free, and paying only if the result looks right. The site also supports OCR for scanned PDFs and ZIP batch upload for translating multiple files in one pass, making it suitable for both single-document jobs and larger file collections.
Key features
OCR for scanned documents
Built-in OCR extracts text from scanned PDFs and image-based pages so they can be translated without manual retyping.
Batch ZIP upload
Upload a ZIP archive, let the system extract the files, and select which documents to translate while keeping folder structure organized.
Preview before purchase
The translation flow uses a free preview before payment, so you can review a sample before paying for the full file.
Custom terminology control
A custom glossary lets you define terms for brand names, technical vocabulary, and recurring phrases across documents.
