Details
How this should help in practice
These sections explain the job in plain language and set expectations for what the tool should do well.
Why this is useful even when the PNG already looks finished
A transparent PNG can look perfect on checkerboard and still break on a dark or warm background. Testing the same asset across several surfaces is one of the fastest ways to catch hidden edge issues.
FAQ
Common questions
Short answers for the questions people usually have before trying a utility like this.
Does this change the PNG by default?
No. The main job is inspection. The export is just an optional contact-sheet snapshot of the test backgrounds.
Can I test a custom gradient?
Yes. The tester includes a simple two-stop linear gradient so soft edge issues are easier to spot.
Does the PNG stay local?
Yes. Preview generation and contact-sheet export happen in your browser.
