Open workbench
Generate an icon, sticker, logo, or UI mark on a flat helper color. Alpha Chroma Studio samples that known backdrop, protects nearby foreground colors, checks the matte, and exports a transparent PNG with local browser processing by default.
Built for planned cleanup
Generic background removers guess the subject. Alpha Chroma Studio is for a deliberate workflow: ask the generator for a flat helper color, then remove that known color with controls made for alpha edges, antialiasing, glow, and compression noise.
It fits icons, stickers, badges, logos, thumbnails, UI marks, and web graphics that need to move into Figma, Canva, websites, decks, game assets, or product docs as transparent PNGs.
Click the backdrop directly and add more samples when generated shadows, glow, or JPEG artifacts shift the background color.
Use result, compare, mask, edge, spill, samples, and background previews to catch halos, pinholes, tint, and accidental subject removal.
Tune tolerance, softness, cleanup, despill, choke, feather, and hole fill. Use erase and restore brushes for small local fixes.
Workflow
Drop a PNG, JPG, or WebP made on a solid helper color. The current tool processes it locally.
Use Key samples for the backdrop, Protect samples for nearby foreground colors, then adjust matte sliders.
Switch between compare, mask, edge, spill, sample influence, and destination background previews.
Download a transparent PNG rendered from the source dimensions, current samples, controls, and paint edits.
Asset proof
Controlled helper-color examples, shown without mascot art or decorative badges. Each case starts on a deliberate backdrop, checks the matte, then previews the transparent PNG on a neutral surface.
A compact UI asset stays sharp while the solid teal source color is removed.
Small lines, dots, and rounded corners remain readable after the backdrop is keyed out.
Transparent corners and hard vector-like edges stay visible on the export preview.
Export checks
Transparent files fail quietly. A rim can disappear on checkerboard and return on a dark website, or a small interior detail can vanish after one aggressive tolerance change.
Local-first trust
The current beta is built for local browser processing. Future cloud features must be explicit, optional, and separated from the default one-asset cleanup flow.

Coming later
Alpha Chroma Studio can grow into a hybrid SaaS, but the local transparent-PNG workflow remains the trust anchor. These later features are not required for the current beta.
Opt-in accounts for reopening assets, samples, masks, and export settings across devices.
Queue many generated assets, standardize helper-color settings, and automate PNG output.
Clearly labeled cloud assistance for cases where local chroma keying is not enough.
