How it works
Browser-side Etsy image preflight
- 1
Upload one JPEG, PNG, GIF, SVG, or HEIC file. JPEG and PNG are the most reliable formats for browser-side analysis.
- 2
QuickPrepMedia decodes the image locally in your browser. No file is sent to a server.
- 3
Deterministic checks run first for readability, supported format, animated GIF rejection, transparency risk, and dimension-based Etsy guidance.
- 4
Heuristic checks run next for thumbnail crop safety, sharpness, watermark risk, and border risk.
- 5
The page groups blockers, warnings, passes, and manual-review items so you can fix the highest-risk issues first.
