Amazon Product Image Preflight

What the Amazon image checker measures

The Amazon image checker reads image width and height, readable density metadata and supported color-mode information. It compares the longest side with a general US size range of 500 to 10,000 pixels. These checks can reveal an undersized source, an unexpected export size or a CMYK image that needs review before a web marketplace workflow.

The implementation also warns below 1,000 pixels as a general zoom-oriented guide. That threshold is not a guarantee of zoom availability or category compliance: Amazon’s product and marketplace guidance can impose different recommendations. Consult the current official requirements for the actual listing instead of treating one local threshold as universal approval.

Check the file you intend to submit

1. Export the actual product image from your editing application. Keep its original source.
2. Choose the .jpg, .jpeg, .png, .tif or .tiff with Choose file. Processing starts locally.
3. Review dimensions, detected metadata, warnings and the near-white edge estimate if available.
4. Download image-check.json for a record of the observations.
5. Compare the image visually with the current main-image and category guidance, then test your normal listing workflow.

The example control uses a demonstration image. The Amazon image checker does not resize, sharpen, crop, remove a background or upload your image to Amazon. Correct a problem in an image editor and inspect the final exported file again; changing an earlier draft does not establish that the submitted version has the same properties.

Example: useful pixel checks without an approval claim

A 1,200 by 1,600 pixel image has a longest side of 1,600 pixels, inside this Amazon image checker’s general size range and above its 1,000-pixel warning threshold. If the format has no readable DPI tag, the report states that resolution metadata is unknown. It does not invent 72 DPI merely because the image looks normal in a browser.

A 400 by 400 pixel version is below the supported general minimum and produces a size finding. Enlarging it numerically to 1,600 pixels changes the dimensions but may not improve useful detail. Inspect the product’s fine edges and labels at the final size, rather than accepting an enlarged file solely because the pixel-count warning disappears.

What the white-edge estimate means

When browser facilities support it, the image is decoded into a small sampling canvas and near-white pixels along its outer edge are counted. A high percentage suggests the edge is mostly light, but it does not inspect every background pixel at full resolution. It also does not distinguish a white product from a white background.

A centered object can have a white border while unwanted text, props or colored patches remain inside the frame. Conversely, a legitimate product touching an edge can reduce the near-white percentage. Treat the value as a prompt for visual review, not a pure-white certificate or a measurement of product occupancy.

Readable metadata and browser limits

PNG, JPEG and TIFF carry different metadata, and not every export records a density value. Unknown DPI remains unknown. The supported color reading is an estimate of identifiable format information, not a complete ICC color-management audit. TIFF decoding can vary by browser: metadata may still be available when the edge sample cannot be generated.

The Amazon image checker bounds decoded image size at 40 million pixels. A file inside the site’s byte limit may still exceed this pixel safety limit. Large compressed images can need substantial browser memory, particularly on a phone, so use a practical listing export rather than an unnecessarily huge production master.

Finish with the actual listing requirements

Read Amazon’s current product image requirements for the marketplace and category. Main images and secondary images can have different content rules. This tool cannot assess authenticity, restricted text, branding, naming conventions or category-specific composition requirements, and does not promise that Amazon will accept a listing.

For images destined for a physical product, the print-ready file checker estimates resolution at a selected print size. If you also supply a product data feed, merchant feed preflight checks selected data fields independently of image content. Use each report to investigate specific problems while preserving the original artwork and following your platform’s own review process.

Common Amazon image checker errors and how to fix them

When the Amazon image checker cannot use a file, it stops with one clear message instead of producing a half-finished download. These are the problems people run into most often, with the fix for each:

• The image is invalid or exceeds 40 million pixels. The file cannot be decoded or is too large for the browser check.
• The file ends unexpectedly. It may be truncated or corrupt. The JPEG or PNG was cut off during transfer.
• Longest side must be between 500 and 10,000 pixels under the general US guide. Resize or export the image again.
• A warning that RGB is preferred A CMYK or grayscale file is flagged for conversion to sRGB.

Privacy: the Amazon image checker runs in your browser

Amazon image checker processing happens with JavaScript in a background worker on this page. Your file is not uploaded to a FileFix server, and the results you download are created in your browser’s memory. Unpublished manuscripts, designs and product data stay on your computer. When you finish on a shared computer, clear the selection or close the tab.
