Browser-based. No quality compromises.

Turn clean pixels into cinematic grunge without losing resolution.

GrangeLab is a high-fidelity grunge engine that runs entirely in your browser. Upload any image, sculpt texture, grain, and analog character, then export at the same or higher resolution with a pixel-safe pipeline designed by a performance-obsessed imaging nerd.

Launch Grunge Studio ↓ No uploads to a server. All processing stays on your machine.

Export quality: Full-res, tuned JPEG/PNG
Pipeline: Non-destructive, repeatable
Engine: Procedural grunge, film grain

Grunge Studio

Upload an image, dial in your texture, then export at full fidelity. Every adjustment is recalculated from the original pixels for a non-destructive, studio-grade workflow.

Supports JPEG, PNG, WebP. We preserve your original resolution on export.

Preview Scale –

Preview uses resolution-aware scaling, export stays full-res.

Drop an image to start grunging.

We will never up-compress or arbitrarily downscale your export.

Grunge engine Procedural

Ready

Presets

Start from a look, then fine-tune.

Texture & Grain

Shape the grit

Texture intensity 60

Macro grunge patterns overlayed using a high-frequency procedural texture. Higher values increase visible grit.

Film grain 30

Micro-level luminance noise, tuned to keep detail while adding cinematic grit.

Sharpness 20

Subtle edge enhancement to counteract grain softness. Kept conservative to avoid halos.

Tone & Color

Match your grade

Contrast 10

Saturation 5

Warmth 5

Bias tones toward cool blue or warm amber without clipping channels.

Fade (matte blacks) 10

Raises shadow floor for a matte, print-like look while preserving midtone detail.

Vignette 25

Edge falloff with a gentle curve, built from the current aspect ratio for natural framing.

Export

Full-resolution only

Exports run the full grunge pipeline against your original resolution. JPEGs are encoded with a conservative quality factor (≈95%) to balance fidelity and size without introducing visible artifacts.

Procedural grunge, not stock overlays

Every texture is generated mathematically based on your image resolution. No stretching, no tiling artifacts, and no baked-in JPEG noise from old scans.

Non-destructive, deterministic pipeline

All sliders map to a repeatable, resolution-aware pipeline. Change your mind, drag a control, and the look is recalculated from pristine source pixels.

Built like a SaaS, without the servers

Your images never leave your machine. It feels like a premium SaaS tool, but everything happens locally with clean, well-audited code.
