CalibRaw: RAW Photo Editor

CalibRaw is a free, open-source RAW photo editor for Linux, Android, Windows and macOS, with a complete photo-development workflow and AI tools that run locally on your device. No account, no subscription, no ads.

The Android app uses the same GPU engine and .calibraw edit files as the desktop app, with layouts made for touch.

DEVELOP YOUR RAW PHOTOS
• Exposure, white balance, contrast, highlights, shadows and saturation
• Luminance and RGB tone curves
• 8-band color mixer and Point Color with an eyedropper
• 3-way color grading for shadows, midtones and highlights
• Sigmoid tone mapping with smooth highlight roll-off and highlight recovery
• Automatic lens correction with Lensfun: distortion, chromatic aberration and vignetting

MASKS AND AI
• Brush, linear gradient, radial gradient and shape masks, each with its own adjustments
• AI masks: select the subject, background, sky, a depth range or any object with a tap
• AI Remove erases distractions and matches the fill to your photo's grain
• AI Denoise for high-ISO Bayer and Fujifilm X-Trans RAWs
• Clone and heal brushes

CREATIVE EFFECTS
• Depth-aware fog and relighting, light rays and smoke
• Glow, halation, edge glow, neon, grain, vignette and pixelate
• Lens, motion, radial and tilt-shift blur
• Apply any effect to the whole photo or inside a mask

MERGE AND STACK
• HDR merge: combine bracketed RAW exposures into one extended-range image
• Focus stacking: combine frames focused at different distances into one image that is sharp throughout

LIBRARY, PRESETS AND EXPORT
• Fast browsing with cached thumbnails, ratings and pick/reject flags
• RAW+JPEG pairs are shown once
• Presets for one photo or a whole selection
• Non-destructive: edits are saved in small .calibraw sidecar files and your originals are never changed
• Export JPEG or lossless JPEG XL (8 or 16 bit) to your gallery
• Edit Replay: export a 30 FPS video of your edit, step by step, for Reels and Shorts

SUPPORTED FILES
RAW files from a wide range of cameras through LibRaw and Rawler, including Canon, Nikon, Sony, Fujifilm (X-Trans), Panasonic, OM System/Olympus, Pentax, Leica and DNG. JPEG, PNG, HEIC/HEIF and TIFF files open with the same tools.

PRIVACY
Editing, AI masks, AI Remove and AI Denoise all run on your device, and your photos never leave it. CalibRaw only goes online to download AI models, once and only after you agree; each model is verified before use. AI tools need a recent, capable device.
