CoTrans is an open-source, free-of-charge manga and image translator that’s quietly making waves among comic lovers. Powered by VoileLabs and carved with a GPL‑3.0 license, this lightweight tool lets you translate text embedded in images—right on the web. It embraces easy sharing options, including Ko‑fi, Patreon, Afdian, Discord, and GitHub for those generous souls wanting to support its dev journey.
What’s on CoTrans?
- Web-based magic: Upload an image or comic (like manga panels), and CoTrans translates text directly in place—no layout destruction, no headache.
- Multiple script support: Ideal for image translation workflows; includes a userscript compatible with sites like Pixiv and Twitter for on-the-fly translating.
- Wide language coverage: Processes Japanese, Chinese, English, and Korean source content—output available in a broad selection of target languages, including Simplified/Traditional Chinese, English, Vietnamese, French, Russian, and more.
- Translation engine variety: Powered by multiple translation backends—Google, DeepL, Papago, Youdao, Baidu, GPT-3.5/4, m2m100 for multilingual coverage, and even “none” (which strips the text so you can manually overlay your own).
- Backed by a solid foundation: Built on the manga-image-translator project (by zyddnys), CoTrans adds a collaborative web-app layer to an already robust open-source base.
