Overview

Error 90217 is a product listing validation error that Amazon returns when a seller submits an image URL containing an unsupported file format. This error blocks listing creation or updates until the image is replaced with a file in one of Amazon's accepted formats. Understanding this error and how to resolve it quickly is essential for sellers who manage product catalogs at scale or use automated listing tools.

Key Points / What Sellers Need to Know

• What triggers it — Error 90217 fires when an image URL submitted for a product attribute contains a file format that Amazon does not recognize or support, such as WebP, BMP, SVG, or other non-standard formats.
• Affected attributes — The error can appear on any image-related attribute field, including the main product image, alternate images, swatch images, and any other field that accepts an image URL.
• Supported formats — Amazon generally accepts JPEG (.jpg/.jpeg), PNG (.png), TIFF (.tif/.tiff), and GIF (.gif) for product images. The exact supported formats are included in the error message itself.
• Blocking behavior — This is a hard validation error, meaning Amazon will reject the entire feed submission or listing update for the affected SKU until the image format issue is corrected.
• Common sources — The error frequently occurs when sellers use bulk upload tools, third-party listing software, or API-based integrations that reference images hosted on external servers in non-standard formats.

How the Error Works

When you submit a product listing or update through Seller Central, a flat file upload, or the SP-API, Amazon validates every image URL against its list of accepted file formats. The system inspects the file extension in the URL to determine the format. If the URL points to an image with an unsupported extension — or if the URL lacks a recognizable image extension altogether — Amazon returns Error 90217 along with the specific attribute name that failed validation and the list of formats it does accept. This means the error message itself is your best guide: it tells you exactly which attribute has the problem and which formats you should be using instead.
