01
Pixel dimensions
Reads the exact width and height from the selected file and shows whether the longest side reaches the 1,000 px recommendation.

What the Amazon image size checker does
This tool checks the dimensions that are actually present in the file. It does not upload the image, spend an AI credit, or promise marketplace approval.
02
Source-quality warning
Warns when the source is too small for the standard workflow instead of implying that enlargement creates real detail.
03
Square JPEG export
Centers the original proportions on a white 2,000 × 2,000 px canvas and exports a predictable JPEG locally.
Amazon US technical guidance
Amazon product image size requirements
Amazon uses pixel dimensions and image quality together. A larger canvas is useful only when the original product photo contains enough real detail.
| Check | Amazon guidance | What PicDo AI reports |
|---|---|---|
| Longest side | 500–10,000 px | Shows the source width, height, and longest side. |
| Zoom guidance | 1,000+ px recommended | Warns when the source is below 1,000 px on its longest side. |
| Resolution | At least 72 dpi | Focuses on pixel dimensions; browser export does not certify print-resolution metadata. |
| File format | JPEG, TIFF, PNG, or non-animated GIF; JPEG recommended | Accepts JPG, PNG, or WebP input and exports JPEG. |
| Image quality | Clear, non-pixelated, without jagged edges | Does not claim that enlarging a small source restores missing detail. |
Square is a PicDo AI preset, not a universal Amazon requirement. The tool uses a 2,000 × 2,000 px white canvas because it is a consistent working size for this connected workflow. Preserve the product proportions and check category-specific guidance before upload.

Three steps
Check, resize, and review
Everything happens in the browser. The export keeps the source aspect ratio and adds white canvas space rather than stretching the product.
- 01
Choose a file
Select a JPG, PNG, or WebP product image.
- 02
Read the dimensions
Review the exact width, height, and small-source warning.
- 03
Export a JPEG
Create the square preset, inspect it, and download locally.
Size is only one check
Review the main image before resizing
A correctly sized file can still have an off-white background, distracting props, weak framing, transparency, or visible quality problems.
FAQ
Amazon image size checker questions
Clear answers about pixels, square exports, image quality, file formats, and local processing.
What size should an Amazon product image be?
Amazon US currently allows 500 to 10,000 pixels on the longest side and recommends at least 1,000 pixels for the best customer experience and zoom. Category-specific rules can be stricter, so review the current guidance for your product type.
Does an Amazon product image have to be square?
Amazon's general technical specification is based on the longest side, not a universal square-image requirement. PicDo AI exports a square 2,000 by 2,000 pixel JPEG as a predictable listing-workflow preset, not as a guarantee or universal Amazon rule.
Does resizing a small image improve its quality?
No. Resizing changes pixel dimensions but cannot restore detail missing from the original photo. If the source is below 1,000 pixels on its longest side or looks soft, use a larger source or enhance it before resizing.
Which image formats does Amazon accept?
Amazon US lists JPEG, TIFF, PNG, and non-animated GIF, with JPEG recommended. PicDo AI accepts JPG, PNG, and WebP as browser inputs for this tool and exports a JPEG; WebP should be re-exported before Amazon submission.
Does PicDo AI upload my image to check its size?
No. Dimension inspection and the 2,000 by 2,000 pixel export run locally in your browser. This resize step does not consume an AI task or credit.
Will a correctly sized image be approved by Amazon?
Not necessarily. Pixel dimensions are only one part of image review. Amazon also evaluates product accuracy, main-image background, framing, clarity, prohibited overlays, category requirements, and other policies that a size checker cannot fully verify.
