A practical logo QA workflow

Start with the grader to catch export and versatility problems. Use the palette extractor to document the dominant colors, then validate important foreground and background pairs in the contrast checker. These checks do not replace a designer, accessibility testing in the final interface, or a trademark search, but they make production problems visible earlier.

Local processing. Tool uploads stay in this browser and are not stored by SimilarLogo.
Explainable checks. Results come from visible technical rules, not invented AI confidence.
Your file only. These tools do not compare uploads against an unapproved public-logo corpus.
Human review remains essential. Technical results are not legal, trademark, or creative approval.
