Overview

Amazon rejects product images that exceed the 10 MB (10,485,760‑byte) limit, returning error 20013. The restriction applies to single uploads and bulk feeds, and it can stall the launch of new listings or updates. Sellers need to understand the size rule, why it’s triggered, and how to keep images compliant without sacrificing visual quality.

Key Points

• Maximum file size is 10 MB — Any image larger than 10,485,760 bytes triggers error 20013 and is blocked from the listing.
• Dimension range matters — Images must be at least 500 px on the longest side and cannot exceed 10,000 px; size and dimensions together determine the final file weight.
• Bulk uploads are vulnerable — In a multi‑image batch, a single oversized file can cause the entire feed to fail, forcing sellers to troubleshoot the whole upload.
• High‑resolution originals are typical offenders — RAW files or uncompressed renders from professional cameras often surpass the 10 MB ceiling before any web‑optimization.
• Compression tools can solve the issue — Free utilities such as GIMP, Squoosh, or native preview apps can shrink file size while preserving acceptable quality.

How to Resolve Error 20013

1. Identify the oversized file — Open the folder containing the images, sort by size, and locate any file above 10 MB; for example, a 12.4 MB RAW photo of a kitchen gadget will appear at the top of the list.
2. Resize the dimensions — Reduce the longest side to a range between 1,600 px and 2,000 px, which typically brings most product photos under the limit; a 4,500 px‑wide image of a smartwatch can be scaled down to 1,800 px without losing detail.
3. Apply compression — Use a tool like Squoosh to lower JPEG quality to 70‑80 % or enable “lossless” WebP conversion; the same smartwatch image might shrink from 9.8 MB to 5.2 MB after compression.
4. Verify the new file size — Right‑click the edited image, view properties, and confirm the size is below 10 MB; if it still reads 10.3 MB, repeat step 3 with a slightly lower quality setting.
