what it does

The edits you need, right now.

The app is deliberately small. Global tone, global color, crop. The things you actually reach for when you're developing a single frame, and nothing else to wade through.

White balance

Temp and tint sliders calibrated against the camera profile, with an auto button that runs gray-world plus a near-gray refinement pass.

Tone

Exposure, contrast, highlights, shadows, whites, blacks. Auto detects clipping at both ends and lifts shadows without crushing midtones.

Color

Vibrance is inverse-saturation weighted in the Velvia style; saturation is a clean chroma scale around Rec.709 luma. No magenta skin.

Crop & rotate

Aspect presets, free ratio, orientation flip, pinch zoom and pan. Your last custom ratio is remembered across sessions.

Histogram

RGB histogram computed on the GPU in the same shader that draws the preview, so it's always exactly what you're looking at.

Export

Full-resolution PNG, JPG, or 16-bit uncompressed TIFF. The export math is the same math as the preview, so what you see is what you save.

why it exists

Because you shouldn't have to get home to edit.

The best moment to edit a photo is usually right after you take it, while the scene is still in your head and the version you imagined is still vivid. That moment rarely happens at a desk. Open Raw Editor goes where the photograph already is: on your phone, on a tablet, on whatever screen is nearby.

Open the app. Drop the file. Push the edits. Save the result. Close the tab and walk away. The next time you come back, it's still a URL, on whatever device you happen to have in front of you.

under the hood

Built for people who read the EXIF.

Where it runs
On your phone, on your tablet, on your laptop. Any modern browser on iOS, Android, ChromeOS, macOS, Windows, or Linux. The same page, the same pipeline, the same pixels.
What stays local
Everything. Your sensor file is unpacked into a 16-bit linear image entirely on your device. Nothing is uploaded, nothing is mirrored.
Export
Full-resolution PNG, JPG, or 16-bit uncompressed TIFF, rendered locally at the original sensor resolution.
Formats
.ARW · .RAF · .DNG · .JPG · .HEIC

What it isn't.

Not a digital asset manager. There is no catalog, no library, no rating system, no batch processing, no AI sky replacement, no presets marketplace.

This is for the moment between the shot and the share. Triage on the way home, finish on the couch, save the final on the desk. One photo at a time.
