Overview

Error 20115 is a common image upload issue that Amazon sellers encounter when adding or updating product listing photos on Seller Central. The error message — "We do not support the file type of the image uploaded" — indicates that something about the image file itself is incompatible with Amazon's requirements. Understanding the root causes and fixes can save sellers significant time when managing their catalog.

Key Points / What Sellers Need to Know

• Supported formats are limited — Amazon accepts JPEG/JPG, TIFF, and PNG image files. Formats like BMP, GIF, and PDF will trigger this error immediately.
• File extensions must match the actual file type — Renaming a file from .bmp to .jpg without properly converting it will still cause a rejection because the underlying data hasn't changed.
• Color mode matters — Images saved in CMYK color mode (common in print design) are not supported. All listing images must use the RGB color profile.
• Maximum resolution applies — Images exceeding 10,000 pixels on either the height or width dimension will be rejected.
• Corrupted files are flagged — Files that were improperly converted between formats or became corrupted during transfer may trigger this error even if the extension looks correct.
• URL syntax is strict — When providing image URLs during bulk uploads, the link must point directly to the image file, not to a webpage containing the image.

Common Causes of Error 20115

There are several scenarios that trigger this upload rejection. The most straightforward is attempting to upload an image in a format Amazon does not accept, such as BMP, GIF, or PDF. However, the error also fires when a file's extension does not match its actual encoding — for example, a PNG file that was renamed with a .jpg extension without being re-saved in the JPEG format. Non-image files disguised with image extensions will also be caught. Additionally, images with unusual color tonal variations or those saved in CMYK color mode rather than RGB can cause the system to reject the upload. Finally, very large images that exceed the 10,000-pixel threshold on either dimension will fail validation.
