Doc2Lang
Doc2Lang is a document translation service built around context-aware AI rather than word-for-word machine translation. Upload a file, preview a sample of the output for free, and pay only when you are satisfied with the quality.
The product covers far more than office documents. It handles Excel, Word, PDF, PowerPoint, CSV, EPUB, HTML, and InDesign IDML files, plus video, audio, images, and subtitle formats like SRT, WebVTT, and ASS. Built-in OCR handles scanned PDFs and image-based content without a separate preprocessing step.
Doc2Lang targets teams and individuals who need translated files that still look like the originals. Layout, fonts, tables, and slide formatting stay intact across formats. Custom glossaries, translation styles, and a retranslate workflow give you control over terminology and tone when the first pass is not quite right.
Billing is pay-per-use with no subscription required. Token-based pricing scales down as volume increases, and bulk credit packs waive the minimum charge for frequent users.

Does Doc2Lang require a subscription?
No. Doc2Lang uses pay-as-you-go billing with no monthly fees or subscription. You pay per translation based on token count, and can also buy credit packs that never expire.
How does Doc2Lang pricing work?
Pricing is based on tokens (roughly one character equals one token in English). Rates drop with volume: $0.50 per 1K tokens for 1-20K tokens, $0.25 per 1K for 20K-60K, and $0.10 per 1K for 60K and above. Pay-as-you-go has a $5 minimum charge, which credit purchases can waive.
Is my data secure on Doc2Lang?
File transfers use HTTPS encryption. You can delete uploaded files at any time, and documents not manually removed are automatically deleted after 14 days. OpenAI processes translations via API without retaining your document data.
