iPhone
Professional photo development that never leaves your iPhone. No account, no cloud.
JK Graphic Editor is a professional photo darkroom that runs entirely on your iPhone. No account, no subscription, no cloud: your photos never leave the device.
DEVELOPED LIKE A PRO
The engine works the way high-end raw developers do: in linear light, with a filmic tone curve that keeps colours true, recovers highlights smoothly and never shifts hues. Import RAW (DNG, CR3, NEF, ARW, RAF and more), HEIC or JPEG.
AUTO THAT CHECKS ITS OWN WORK
Pick a look and the app develops your photo, then measures the result against professional limits: clipped highlights, crushed blacks, colour casts and oversaturation. If something fails, it corrects itself before you see it.
REFINES YOUR CAMERA, NEVER UNDOES IT
Natural, Portrait, Landscape and Food keep your camera's white balance and exposure and only polish the picture, then compare the result with the camera's own file: no new clipped highlights, no colour noise in the shadows, night scenes stay dark, never softer.
TRUE IPHONE COLOUR
iPhone photos stay in Display P3 from import to export, so saturated colour and bright skin are not clipped. ProRAW follows the camera's own local tone map, and Apple's skin detection protects faces.
11 LOOKS
Natural, Portrait, Landscape, Product, Food, Street, Moody, Night, Black & White, Film Warm and Teal & Orange.
FULL CONTROL
- White balance from real neutrals, Kelvin, warmth and tint
- Exposure, contrast, highlights, shadows, whites and blacks without halos
- Clarity and noise-aware texture
- Vibrance, saturation and per-colour adjustments with skin-tone protection
- Black & white with colour filters, vignette, sharpening, noise and colour-noise reduction
- Undo and redo, and one tap to compare with the camera's original
- Straighten, smart crops for 1:1, 4:5, 9:16 and 3:2
FACES, HORIZONS AND SUBJECTS
Apple's on-device Vision finds faces for metering, levels horizons and keeps your subject in frame when cropping.
NON-DESTRUCTIVE
Originals are never touched. Every edit is saved as settings next to a copy you can see in the Files app, and can be reset at any time.
EXPORT
Full-resolution JPEG or HEIC, or sized and sharpened for Instagram posts and stories. Keeps the capture date and camera details, with a switch for location. Save to Photos or Files.
PRIVACY
The app collects no data at all and makes no network connections.
