JK Graphic Editor

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. 12 LOOKS Natural, Portrait, Landscape, Product, Coffee, 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 and noise reduction - 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. Save to Photos or Files. PRIVACY The app collects no data at all and makes no network connections.
