Long edge
Waiting for an image
Tool check threshold: 2000px. Etsy Help states: “We recommend your listing photos have a width and height of at least 2000 pixels or more.”
The long-edge check is a screening shortcut requested for this checker; it is not the same test as Etsy Help’s width-and-height recommendation.
File size
Waiting for an image
Reference: Etsy Help says images larger than 1MB may not finish uploading, especially on a slower connection.
Aspect ratio
Waiting for an image
Preview candidates: 1:1 square and 3:4 portrait. Etsy Help describes square, portrait, and landscape thumbnail crops; 3:4 is a preview choice, not a stated Etsy upload requirement.
File type
Waiting for an image
Etsy Help lists .jpg, .gif, .png, .svg, and .heic as supported file types.
Centered crop previews
1:1 square crop — shaded regions fall outside the crop.3:4 portrait crop — shaded regions fall outside the crop.
These previews center the crop box on the image. Etsy’s actual thumbnail adjustment tool can preview and adjust listing thumbnails in different Etsy placements.
