Linear Raw is the only free app that batch converts almost any RAW image into the highest quality 16-bit DNG. No internet or account required, all processing is native on device. If you experience any issues, please reach out to the developer at linear.raw@gmail.com

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 LibRaw C++ engine, Linear Raw 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 - Linear Raw extracts comprehensive EXIF 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. 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 - 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.
