Waiting for an image

Upload a product image to see dimensions, ratio, weight, format, and platform fit notes.

How It Works

  1. 1Choose or drag a product image into the upload area.
  2. 2The browser reads the image dimensions, file size, MIME type, and aspect ratio locally.
  3. 3Review the result panel for simple platform fit notes and practical next steps.

Best Practices

  1. 1Use consistent image ratios across a product set so grids and galleries feel intentional.
  2. 2Keep important product edges visible with enough breathing room around the object.
  3. 3Compress large files after export so storefront pages stay fast on mobile connections.

FAQ

Are images uploaded to a server?

No. This checker uses browser APIs to inspect the selected file locally.

Is 800 x 800 always enough?

It is a useful minimum for many workflows, but larger square images can be better when a marketplace or store supports zoom.

Which formats should I use?

JPG, PNG, and WebP are common web formats. JPG is often efficient for photos, PNG can preserve clean graphics, and WebP can reduce file weight.
