Every function, explained.

One page per function: what it's for, how it works, every setting, the CLI call, FAQ and limits. The source is the app's function reference — nothing is invented here.

Chroma-key profiles free

All nine profiles are free — keying quality is never paywalled.

Green Sprite (green screen keying) free
The classic green screen remover for pixel-art sprites: green background out, hard edges in — no scaling.
--profile green
Green Sprite (hard, content-safe) free
Remove a green screen without eating green subject matter: only edge-connected green goes, enclosed interior green stays.
--profile green_hard
Residue Repair free
Strip the green haze and speckles off sprites you've already cut out — the content stays untouched.
--profile residue
Auto free
Measure the key per image and cut out with a soft matte — ideal for mixed green/magenta batch folders.
--profile auto
Custom Color free
Remove any key color via a distance tolerance — for backgrounds that are neither green nor magenta.
--profile custom
Magenta Sprite / Outline free
Cut out magenta-keyed sprites with a hard dark outline — only the background goes, enclosed magenta in the subject stays.
--profile magenta_sprite
Magenta FX / Water free
Cut out magenta-keyed water, light and energy FX — edges are cooled instead of neutralized to black.
--profile magenta_fx
Magenta FX / Water Plus free
Remove stubborn pink and lavender fringes from magenta FX — neighbor-color-assisted, for the problem cases.
--profile magenta_fx_plus
FX / Glow (Soft Matte) free
Cleanly cut out translucent glowing effects — glow, smoke, sparks, energy — with soft alpha instead of a hard 0/255 cut.
--profile fx_glow

Transform operations

Pixelize (pixel-art converter) €12
Turn painterly and AI-generated images into convincing classic pixel art — low resolution, curated palette, clean flat areas.
--operation pixelize
Pixel-art UnDetail €3
Bring over-detailed PNG assets down to a coarser pixel structure on purpose — no gray fringes, edge artifacts, or RGBA mush.
--operation undetail
Asset Slice (9-slice / 3-slice) €9
Bring UI panels, buttons and frames to any size distortion-free — corners stay fixed, edges and center scale.
--operation slice
Asset SliceX (free grid cutting) €9
Cut sprite sheets, textures and UI atlases along freely placed lines into up to 25 cells — each cell as its own PNG.
--operation slice-grid

Capabilities & utilities

Batch processing €9 · Batch & Automation
Process a whole folder in one run — with an overwrite strategy, file list, report and cancel.
GUI · Batch-Tab
CLI / Automation (overview) requires Batch
Every operation in the app can be called headless — for scripts, pipelines and batch runs over a whole folder.
clean_sprite_chromakey.exe
Update check free
Check whether a newer version is available — anonymously, without sending any image or user data.
--check-update
