Frequently Asked Questions
Are my images uploaded to a server?
No. All image processing happens locally in your browser using Canvas API. Your images never leave your device.

You can upload JPG, PNG, WebP, and GIF images. Output can be converted to JPG, PNG, or WebP.
What size should Amazon product images be?
Amazon recommends at least 1000x1000 pixels (max 10000x10000). Images larger than 500px enable zoom. 2000x2000 is the most common size.
