Your creative never leaves this browser
Brand compliance checker for design assets.
Catch measurable brand drift before handoff. BrandPreflight checks colors, typefaces, logos, WCAG contrast, terminology, and SVG quality locally in your browser—without uploading creative files.
Sample preflight
Ready to review
Evidence over guesses
Flattened fonts, ambiguous backgrounds, and low-confidence logos are labeled “Needs review” instead of receiving a false pass.

A synthetic demo profile is included so you can inspect the complete workflow before creating your own.

One evidence trail across the brand system
BrandPreflight separates what can be measured from what still needs professional judgment. Every automated finding includes the rule, observed evidence, and a practical repair action.
WCAG color contrast
Calculate AA and AAA contrast thresholds for any foreground and background pair.

Run a complete preflightStep 1
Define confirmed rules
Build a local profile from approved colors, fonts, logo references, spacing rules, terminology, and output presets.
Step 2
Check the final export
Drop in an SVG, PNG, JPG, or WebP. Analysis runs in a local worker, and the creative file never becomes an upload.
Step 3
Fix from evidence
Review failures and uncertainty separately, then preserve the report as a repeatable design QA record.
Questions before your first preflight
Does BrandPreflight upload files?
No. Creative analysis, guideline extraction, profiles, and reports remain in this browser. Only checkout and license validation use the network.
What file types are supported?
You can review SVG, PNG, JPG, and WebP exports up to 25 MB. SVG files provide the strongest evidence for typography and copy.
Does a high score replace review?
No. Coverage is shown separately, and uncertain checks remain visible so missing evidence cannot become a false pass.
