Linear Raw: DNG Converter

Linear Raw is a high-performance utility designed for photographers who need to convert RAW image files from most major brands into professional-grade 16-bit Linear DNGs directly on their Android devices.

Linear Raw provides the bridge between your camera and mobile editing suites like Snapseed and Lightroom, without compromising image quality.

High-Fidelity Conversion - Powered by the industry-standard LibRaw C++ engine, Linear Raw bypasses standard mobile image processing. It extracts the raw sensor data and preserves the full dynamic range in a 16-bit Linear DNG format, giving you maximum flexibility for color grading and exposure recovery in post-production.

Professional Metadata & Calibration - Don’t lose your technical data. Linear Raw extracts comprehensive EXIF and MakerNote information, including:
• ISO, Shutter Speed, and Aperture.
• Focal Length and Lens Model.
• Camera Body Serial Number.
• Precision sensor calibration: Black/White levels, CFA (Bayer) patterns, and model-specific color matrices.

Efficient Batch Workflow - Convert entire shoots at once. Our robust background service allows you to queue multiple RAW files directly from an external card reader and continue working or switch apps while the conversion completes.

Privacy-First & Offline - Your photos are your business. Linear Raw performs all conversions 100% on-device. No images are ever uploaded to a server, and no internet connection is required for the conversion process.

Modern Design - Built with Jetpack Compose, Linear Raw features a beautiful, responsive interface with full Dark Mode support and optimized layouts for both phones and tablets.
