Amazon Secondary Image Checker
Amazon Secondary Image Checker helps you preflight measurable file, dimension, duration, text, or upload fields before using an official or platform workflow.
The checker returns pass, warn, and fail items, a copy-all result, source references, and local repair links where a TextFaker tool can help.

What this preflight checks
Amazon Secondary Image Checker is a base verification utility for measurable fields, not a human review or official approval service. It reads local file metadata where the browser exposes it and accepts manual values for fields that cannot be safely inferred in the browser.
Common checks include file extension, file size, pixel dimensions, and aspect ratio where the requirement can be measured from the selected file or entered dimensions.
- Marketplace image format: File extension should be one of: jpg, jpeg, png, webp.
- File size limit: File size should be 10 MB or smaller.
- Minimum dimensions: Dimensions should be at least 1000 x 1000 pixels.
- 1:1 aspect ratio: Aspect ratio should be close to 1:1.
How to read the result
A pass item means the provided value met the local rule. A warn item means the checker needs more source data, such as page count, DPI, duration, or pasted markup. A fail item names a measurable value that is outside the configured preflight rule.
Use the copy-all button to save the full report with labels, input values, checks, and reference names. That makes it easier to compare fixes before uploading again.
- Pass: the provided measurable value fits the configured rule.
- Warn: the checker needs more local data before it can decide.
- Fail: fix the file, dimensions, duration, text, or naming issue before submission.
Sources and variants
Amazon Secondary Image Checker stores official or standards references with the base checker. Country, region, or platform variants should be added as data presets only when their source URL, last-verified date, and allowed jurisdiction are present.
This base checker does not publish country variants unless a future preset includes an approved jurisdiction and source-backed rules.
- Source policy: official-required.
- Base variant count planned: 0.
- Demand proof URLs stored: 2.
