The 5-Stage Downscale Pipeline

Configure and isolate every stage of the downscaling process step-by-step in real-time to analyze asset viability.

Stage 1

Auto-Crop Zoom

Intelligently detects borders of transparent or white backdrops. Automatically centers your asset bounds inside a unified perfect square.

Stage 2

Grid Upscaling

Rescales the crop back up to 1024x1024 using selectable filters like Retro Sharp Nearest Neighbor to ensure precise grid alignments.

Stage 3

Background Keying

Strips out bright white backgrounds or custom edge borders. Adjustable sensitivity sliders help to easily key out anti-aliased halos.

Stage 4

Geometry Resampling

Downscales the grid to pixel assets at every resolution — 16x16, 32x32, and 64x64 — with Nearest Neighbor, Box, and advanced mode downscalers.

Stage 5

Alpha Solidification

Applies a razor-sharp threshold to alpha channels. Instantly clears half-transparent pixels to guarantee 100% retro rendering compatibility.

Everything Included, Free

No tiers, no accounts, no payment. Every feature runs locally in your browser.
