Overview

Amazon has specific technical requirements for product images that every seller must follow to get their listings live and performing well. Understanding these specifications — from file formats to color modes — helps ensure your images display correctly across all devices and qualify for features like zoom functionality.

Key Points / What Sellers Need to Know

• Main image is mandatory — Every product listing on Amazon must include at least one main image, with Amazon recommending a minimum of six images plus one video per product.
• JPEG is the preferred format — While Amazon accepts JPEG, TIFF, PNG, and non-animated GIF files, JPEG is the recommended format for best compatibility and performance.
• 1,000+ pixels enables zoom — Images must be at least 1,000 pixels on the longest side to activate the zoom function on product detail pages, which can significantly impact conversion rates.
• RGB color mode is essential — Although Amazon technically accepts CMYK, RGB is strongly preferred because CMYK images often display with noticeable color shifts on screens.
• Several common formats are banned — Amazon does not accept proprietary file formats such as PSD, EPS, BMP, PDF, and several others.

File Format and Size Requirements

Amazon accepts four image file formats: JPEG (.jpg or .jpeg), TIFF (.tif), PNG (.png), and non-animated GIF (.gif). Among these, JPEG is the clear recommendation from Amazon. Images must be a minimum of 72 dpi and at least 1,000 pixels on the longest side, though they cannot exceed 10,000 pixels on the longest side. For the best visual quality, sellers should submit images with minimal or no compression applied. When working with JPEG files specifically, always save at the highest quality setting and avoid repeatedly saving in JPEG format during editing, as each save cycle degrades image quality. For TIFF files, do not apply any file compression, and regardless of format, remove all layers from images before uploading.

Formats Amazon Will Reject

Sellers should be aware that Amazon will not accept images in proprietary or print-oriented file formats. The banned list includes EPS (Encapsulated PostScript), BMP (bitmap), PDF (Portable Document Format), PSD (Photoshop native files), and several application-specific formats such as CDR (CorelDRAW), FLA (Flash), PICT (Mac OS X default), and DOC files. Even if an image meets all other technical specifications, Amazon reserves the right to reject any image that does not comply with their content standards. This means sellers need to convert any working files into one of the four accepted formats before uploading.
