Runs locally

Detection, OCR, and inpainting all run on your machine via ONNX Runtime + DirectML. No page ever leaves your computer unless you choose a cloud translation provider.

GPU or CPU

DirectML picks up NVIDIA, AMD, or Intel GPUs automatically on Windows, and falls back to CPU if no compatible GPU is available.

Bring your own translator

Google Translate works out of the box without an API key. You can also plug in DeepL, DeepSeek, ChatGPT, Grok, Gemini, Claude, or OpenRouter with your own key.

Not just the desktop app

A Chrome extension and a Tampermonkey/Violentmonkey userscript translate manga images on any website, using the same local backend - including on iPhone and iPad Safari.

Current release ​

  • Version: v1.2.0
  • Platform: Windows 10 (1903+) / Windows 11, x64
  • GPU support: DirectML (NVIDIA / AMD / Intel) with automatic CPU fallback

What's new in v1.2.0

  • Google Translate is now the default provider and requires no API key.
  • Target-language handling fixed. Google translations now honor Simplified Chinese, Traditional Chinese, English, Japanese, French, and German selections instead of silently returning the source text on an upstream error.
  • Faster Google translation. OCR lines are translated in one batch, the working web endpoint is used first, and network connections are reused.
  • Smaller uploads. The desktop app, Chrome extension, and userscript compress images over 500 KB to a maximum 1920 px edge at JPEG quality 60, only when the result is smaller.
  • Chrome extension and userscript updated to v1.2.0 with matching defaults and controls.

See Hardware Requirements for disk space, RAM, and VRAM details.

Local vs. remote server ​

MangaTrans Reader bundles its own backend and starts it automatically on first launch (local mode) - nothing to install separately. If you're running the backend on another machine on your network (or a server), point the reader at it instead (remote mode) via Settings → Server.
