Hi, I'm Harry, the founder of SizeSpec. It launches here on Sunday, November 1.

I built it because every marketplace wants product photos in its own size, shape and file size. Etsy, eBay, Amazon, Shopify, WooCommerce, the App Store and Google Play each have their own rules, and redoing every photo by hand for each one takes forever.

You drop your photos into SizeSpec, pick the marketplace, and get a ZIP with every photo resized, cropped and compressed to that marketplace's rules. The resizing runs in your browser, so those photos are never uploaded.

Most sellers also have a few photos that are just bad: a cluttered desk, dark light. So there is an optional AI tool too. You upload one of your own photos, pick a white background, a styled surface or just better light, and get a cleaner version back in about a minute. That one does send the photo to our AI provider, because the AI has to see it. If you have no photo at all, you can describe the product and generate one.
