Simple workflow

How it works

Add images

Select a product photo batch. Files stay on your device while the browser reads them.

Review the checks

See dimensions, aspect ratio, file size, format, and background whiteness beside each marketplace guideline.

Download fixes

Apply a square white canvas, resize, convert, compress, and rename the batch, then download one ZIP.
