Keep the repaired raster
No additional smoothing or vector reconstruction.
After detecting multiple icons in an icon sheet, AI-generated asset board, or design screenshot, repair each PNG or WebP boundary independently. Keep the original, apply light raster smoothing, rebuild only the edge, or create scalable SVG paths.

No additional smoothing or vector reconstruction.

Applies conventional anti-aliasing to lightly jagged edges.

Preserves raster colors, gradients, shadows, and textures.
Creates scalable paths and reconstructed color regions.
These previews explain the rendering model. Exact smoothing depends on the uploaded edge, transparency, Repair settings, and target output size.
IconSplit traces alpha contours rather than using the SVG color model as a mask. The repaired raster remains the color source. Pixels away from the boundary keep the repaired PNG or WebP appearance, while the edge receives a newly rasterized smooth alpha boundary.
IconSplit has tested both the production V4.2 contour fitter and an experimental V5 pipeline based on signed distance fields and local primitive fitting. V5 preserves topology and offers better diagnostics, but on the reviewed flat-icon set it can preserve too much of the original pixel staircase when a local candidate fails its geometry checks. V4.2 currently produces the more visible improvement on the common flat icon cases, so it remains the production path while V5 stays experimental.
This is not a claim that one method wins on every image. Hand-drawn strokes, glass effects, thin lines, circles, sharp corners, and layered shapes fail in different ways. The public extraction benchmark keeps representative successes and failure cases visible as the algorithms change.
Outer boundaries and enclosed holes are treated as topology, so an icon should not become one solid filled silhouette.
Preview against light, dark, and checkerboard backgrounds to expose contaminated transparent RGB and edge residue.
Choose Vector smoothing when gradients, textures, glass effects, or shadows should remain closer to the original PNG.
| Goal | Recommended mode | Result | Color behavior |
|---|---|---|---|
| Light edge cleanup | Standard smoothing | PNG or WebP | Preserves raster color |
| Smooth fitted boundary | Vector smoothing | PNG or WebP | Preserves raster color |
| Editable scalable paths | Create SVG | SVG | Rebuilds color regions |
