Questions about processing
Is my photograph uploaded to a server?
No. Reading the photo, rendering the preview and preparing the JPG all happen in your browser on your device.
Can I keep the whole product in a 3:4 frame?
Yes. Choose “Keep the whole image” to preserve the entire photograph with white margins. Cropping can remove content at the edges.
Does this tool generate a background with AI?
No. It changes the size and placement of an image. For generated backgrounds or scenes, open the Progon studio.
Will the output be approved by a marketplace?
The aspect ratio alone is not enough. Check the current platform requirements, image quality and whether the photograph accurately represents the product.
