A downloaded PNG can have a transparent background and still be unusable. That happened with our own logo: the background disappeared, but the badge became faint too.
Our general background-removal pipeline needed a different path for flat artwork. We added conservative handling for opaque, limited-color images with a nearly uniform border. Inputs that do not meet those conditions continue through the existing model workflow.
The important distinction
The sample contains a white letter inside a green badge, surrounded by a white canvas. Removing every white pixel would damage the letter. The implementation identifies surrounding, edge-connected background instead, preserving disconnected white artwork inside the badge.
Boundary cleanup handles partially blended pixels along the edge. Those pixels can change; preserving artwork does not mean every pixel remains byte-identical.
Verify the delivered PNG
On October 5, 2026, we tested the deployed auto/pro workflow through our website. The surrounding background became transparent, representative solid-green and white-letter pixels retained their original colors and alpha 255, and dimensions remained 512 by 512.
Output SHA256: 5e3260a508b82090638a8d0c2d1fb01f29f4b8e93c3186433069877443d098d3. The actual file and short website workflow are available in our transparent-logo tutorial.
This verifies one flat-logo case. Gradients, shadows, and complex artwork may behave differently. Check the exported image on its destination background.
