Open a photo
Your browser decodes the image locally. MintGrade creates an autosaved local project so you can return to the grade later.
MintGradePrivate browser color gradingProfessional photo color grading, directly in your browser.
Grade photos with 24 LUTs and filters, curves, HSL, background removal, blending layers, scopes and reference matching without sending the image to an application server. MintGrade keeps the workflow fast, editable and local-first.

How MintGrade works
A photo color grading workflow that stays understandable.
Start with correction, build the look, check the image, then export. Advanced controls appear when you need them instead of covering the photo.
Correct and grade
Use exposure, curves, HSL, categorized LUTs, background masks, blending layers, color wheels and a reference image while the photo remains visible.
Check and export
Use histogram, waveform, RGB parade, vectorscope and Grade Health, then render the original at full resolution in GPU tiles.
Built for grading
More control than filters, less clutter than a desktop suite.
MintGrade focuses on the decisions that change color and tone instead of trying to become a generic graphics editor.
◇
3D LUT editor
Import standard .cube LUTs, use tetrahedral interpolation, adjust strength and export reusable grades.
⌁
Curves + HSL
Shape master and RGB curves, then target eight color families with hue, saturation and luminance controls.
◉
Three-way color wheels
Push shadows, midtones and highlights independently without burying the image under controls.
◎
Reference matching
Analyze another image for broad tonal and color character, then keep the result fully editable.
◐
Range masks
Constrain creative adjustments by luminance and hue, soften the selection and inspect the mask directly.
▥
Professional scopes
Check histogram, waveform, RGB parade and vectorscope while clipping, zebra and false-color overlays reveal exposure problems.
✓
Grade Health
Flag highlight clipping, crushed blacks and extreme color before those problems reach the final export.
↓
Tiled full-resolution export
Re-render large originals in overlapping GPU tiles instead of permanently exporting the smaller editing preview.
✂
Background erase + recovery
Remove border-connected backgrounds automatically, refine with an Erase brush, and paint the original background back with Recover.
▱
Layers + blend modes
Add image or color layers above the photo or behind a cut-out subject, then control order, opacity and professional blend modes.
↺
Autosaved local projects
Grades, background masks, layers, versions, LUT state and recovery checkpoints are stored in browser storage so accidental refreshes are less painful.
Private by design
Photo editing without an upload queue.
The core grading workflow runs on your device. That makes MintGrade useful for personal photos, client work and large images you would rather not send to a random conversion server.
- Photo processing stays in the browser in this build
- Projects use local IndexedDB storage
- Editor and Projects pages stay free of advertising
- Reference-image analysis runs locally
Desktop and mobile
The photo stays visible while you grade.
MintGrade adapts around the available editor area rather than squeezing a desktop layout onto a phone. Controls dock below the image in portrait and beside it in short landscape layouts.
- Touch-safe sliders that preserve vertical scrolling
- Direct draggable before/after divider
- Responsive tool density for split-screen laptops
- Adaptive preview sizing around the real canvas area
Useful starting points
Choose a look, then make it yours.
Browse 24 categorized LUTs and filters with individual preview photos, then refine the direction with curves, HSL, masks, LUT strength, layers and color wheels.
FAQ
Questions before you open a photo.
Short answers about privacy, LUTs, mobile use and exports.
Does MintGrade upload my photos?
In the current build, the grading workflow decodes and processes selected photos locally in your browser. It does not intentionally upload the image to an application server.
Can I use .cube LUT files?
Yes. MintGrade imports standard 3D .cube LUTs, applies them with tetrahedral interpolation and provides a strength control.
Can I use MintGrade on a phone?
Yes. The responsive editor docks controls away from the image so the photo remains visible while you adjust it. Performance still depends on the device and image size.
Does MintGrade export at full resolution?
Yes for browser-decodable images within device memory limits. The exporter re-renders the original in GPU tiles instead of simply saving the smaller preview.
Is this a RAW developer?
Not yet. The current production build focuses on browser-decodable image formats. Native RAW decoding and full ICC color management are separate engineering work and are not claimed as finished features.
