Welcome to the Shopify community!
and Thanks for your Good question.

So I will check and provide a solution here.
I noticed that you wanted to apply discount badges (with % value) on your catalog images.
We have developed an app (Modemagic) that will help you add product stickers/badges on your catalog within seconds. And we have an extensive collection of customized stickers based on different occasions (Sale & Discounts, Pre-Order, Trust Badges and much more) You can also create custom badges based on what copy you prefer.
Over here, you can choose what value of discount you would like in the badge, customizability is available.
No complex edits, no back & forth with designers. Update your store within seconds!
Don’t find a sticker that meets your need, reach out to us on chat for a custom design. We also create stickers in various languages. Check out this app on Shopify here.
Hope this helps
