Privacy-focused, GPU-accelerated media converter built in Rust
Transmute is a high-performance media conversion tool that processes images and PDFs locally on your machine with optional GPU acceleration. No cloud services, no telemetry, no network calls — your files never leave your device.
- Format Conversion: Convert between PNG, JPEG, WebP, TIFF, BMP, GIF, and PDF
- Image Compression: Optimize images with adaptive quality settings
- Multi-Image to PDF: Merge multiple images into a single PDF document
- Batch Processing: Convert multiple files in parallel with progress tracking
- GPU Acceleration: Optional GPU-accelerated processing via wgpu (Vulkan, Metal, DX12)
- Natural Language Commands: Execute conversions using natural language
- CLI & GUI: Choose between terminal interface or graphical application
- Android Support: JNI bridge for native Android integration
- Privacy-First: Zero network I/O, all processing happens locally
- Configurable: Persistent settings with TOML configuration file
