Hi Product Hunt 👋

If you sell on more than one marketplace, you know every one wants different photos: Amazon a square on pure white, Etsy landscape, Poshmark portrait, each with its own size and file limit. Sellers end up redoing the same pictures again and again, so I built SizeMyListing.

How it works: drop your photos, tick the marketplaces you sell on, download one ZIP with a folder per marketplace.

What I cared about:

🔒 Photos never leave your device. Everything runs in the browser.

📏 Every size comes from the marketplace's official help page, with the date it was last checked.

🌍 English, French and Arabic.

✏️ Custom sizes too, for anything not on the list.

It's free, with no account. What would make it more useful for you? I'm reading every comment today.
