O Translator

This is the core of O Translator, and the reason people pick it over a text translator. Most tools can't preserve document formatting. This one can. The service reads the structure of your file and rebuilds it in the target language, so paragraphs, images, tables, and page flow stay where they belong. It handles PDF, Word, Excel, PowerPoint, EPUB, HTML, and TXT, and the company puts the file-type count above 40.

Beyond standard mode, O Translator offers a Professional tier that runs on advanced AI models including GPT-4.1 and Gemini Pro. It costs roughly three times the standard rate and is aimed at academic papers, legal contracts, and business reports where terminology and context matter more than speed. Standard mode handles most everyday documents at a fraction of the cost.

Scanned PDFs and image-heavy files normally can't be translated because there's no selectable text to read. O Translator runs OCR to pull text out of images first, then translates it. This is the only way to translate a scanned Word document or an image-heavy PDF you can't select text in. Scanned PDF pages are estimated at about 1,200 tokens each, and embedded images at roughly 500 tokens, so you get a cost estimate before committing.

Instead of a subscription, O Translator sells credits. One English word counts as roughly one token, and standard mode converts 3,000 tokens into a single credit. Buying bigger packages lowers the unit price, with discounts up to 40-50% at higher tiers. Credits never expire, so a purchase you make this year still works next year.

You can run a translation and read the complete result before spending anything. The service shows the finished output so you can judge quality first, then pay to download it. That removes the usual gamble of buying credits before knowing whether the translation is any good.

For teams that want to automate the work, O Translator offers a translation API and a developer center. You can plug document translation into your own pipeline instead of using the web interface each time. This is the path for anyone processing a steady volume of files programmatically. It's an AI translation tool you can call from code, not just a website you click through.

The platform steps outside office documents. It translates CBZ and CBR comic files in one click, transcribes and translates audio and video into subtitles, and can extract an audio track from a video. For anyone localizing webtoons, videos, or podcasts, these modes cover formats a document-only tool would ignore.

Text translation lets you define rules and a term base so specific words are handled the way you want. When matched text appears in a document, the system applies your rule and drops the chosen translation back into place. Teams share term bases too, which keeps terminology consistent across a whole project.
