Tonvra: photo editor

Tonvra is a non-destructive photo editor built for people who want real control over every image, with no automatic filters and no artificial intelligence involved.

Every adjustment lives in its own edit document: your original photo is never touched, and you can undo, redo, or roll back at any time.

📷 LIGHT & COLOR
• Exposure, contrast, highlights, shadows, whites, and blacks
• Parametric tone curves, RGB point curves, and per-channel curves
• White balance with eyedropper and presets
• 8-color HSL mixer (hue, saturation, luminance)
• Color grading with shadow, midtone, and highlight wheels
• Black & white conversion with per-color mixer
• Color profiles and RGB primary calibration

✨ EFFECTS & DETAIL
• Texture, clarity, and dehaze
• Customizable vignette and film grain

🖼️ CROP & GEOMETRY
• Crop with aspect ratios and composition guides
• Straightening and manual perspective, rotation, and scale transforms
• Manual lens distortion and vignetting correction

🎯 LOCAL MASKS
• Linear and radial gradients, plus a manual brush
• Edge-aware auto-mask (contrast-based, no AI)
• Color range and luminance range selection
• Combine masks by adding, subtracting, or intersecting

🩹 RETOUCH & LIQUIFY
• Heal and clone stamp tools
• Manual red-eye removal
• Liquify brush: push, pinch, bloat, twirl

📁 WORKFLOW & LIBRARY

• Unlimited history, named snapshots, and virtual copies
• Albums, star ratings, flags, and color labels
• Import JPEG, HEIC, and PNG; export in high quality

Edit offline: your photos are processed on your device, not on a server.

Tonvra is built for people who'd rather edit with precision than magic buttons.
