System requirements

VN Translator runs in the browser. For the smoothest experience, use a modern desktop browser.

Recommended setup

• OS: Windows / macOS / Linux
• Browser: latest Chrome / Edge / Firefox
• RAM: 8 GB+ recommended for large projects
• Storage: enough space for exported files + backups

Mobile support

You can open the docs and some tools on mobile, but serious translation work is best on desktop because:

• large JSON and .rpy files require memory
• long sessions are easier with a keyboard
• some features (like folder access) vary by browser

Browser features used

Some tools use modern APIs:

• File picker: for uploading a file
• IndexedDB: for stable local session storage (translation state, preview sync, auto-save)
• File System Access API (optional): for folder-based workflows (best on Chromium browsers)

If a feature is not supported in your browser:

• use a file-based workflow (export/import ZIP or single files)
• or switch to Chrome/Edge for advanced folder access

Connectivity

• Translation APIs require a stable internet connection.
• If you use a free service (Lingva/Google), expect occasional downtime or throttling.

Troubleshooting performance

If the UI becomes slow:

• translate fewer files at a time
• lower batch size
• close other heavy tabs
• clear old sessions (see: Privacy & security)
