🧭 Overview

LangBatcher is a powerful desktop tool for local batch translation of files, documents, and structured content.

Add files or entire folders – and LangBatcher handles the full translation process:

• Translates JSON, PO, TXT, Markdown, HTML, PDF, DOCX, XLSX, PPTX, and images
• Automatically detects file types and applies suitable translation strategies
• Protects placeholders, keywords, regex patterns, and structured content
• Fills missing PO entries without overwriting existing translations
• Processes code and config files using safer key-value heuristics
• Supports multiple target languages in a single run
• Uses local AI models for offline-first translation workflows

Perfect for developers, agencies, shop owners, localization workflows, internal teams, and recurring translation tasks.

🚀 Highlights

• Offline-first batch translation in 100+ languages
  Translate large volumes of files locally on your desktop – no cloud required, powered by local AI models.

• Smart file type detection
  LangBatcher does not treat files as plain text but selects the safest processing strategy based on file type.

• Wide format support
  Process documents, structured text files, Office files, PDFs, images, and code/config files in a single queue.

• PO translation with missing-only mode
  Fill only missing msgstr entries in .po files while keeping existing translations untouched.

• Safer code & config translation
  Translate only human-readable content in files like Python, JavaScript, TypeScript, YAML, TOML, INI, CFG, .env, or properties files.

• Keyword & placeholder protection
  Protect product names, IDs, variables, template placeholders, and other critical content from unintended translation.

• Regex rules & dictionary corrections
  Use protection patterns and post-translation replacements for consistent terminology, branding, and fixing known translation issues.

• Multiple target languages per run
  Generate multiple language outputs in a single batch with status tracking, progress visibility, and partial results retention.

• PDF & image workflows
  LangBatcher uses best-effort redraw for PDFs and local OCR/replacement logic for image-based content.

• Cross-platform desktop tool
  Available for Windows, macOS, and Linux.

💡 Typical Use Cases

• Translate language files for apps, tools, or websites
• Automatically complete missing entries in PO files
• Prepare JSON, YAML, or config files for multilingual projects
• Export PDFs, Office files, and documentation into multiple languages
• Localize product texts, help files, and Markdown documentation
• Translate images with text using local OCR workflows
• Maintain consistent terminology with dictionary and protection rules
• Standardize recurring translation processes using presets
