Rozetpix
When the price changes, the picture does too.
Rozetpix prints the price from Shopify onto your product image, inside your own frame. Change the price and the image is printed again for every ad feed.

( 01 · The problem )
The ad still says 25% off.
Catalogue ads show the bare product photo, so the sale lives only in a line of text. Stores that bake the offer into the image do it by hand, and when the sale ends the old badge keeps running in Meta, TikTok and Google until someone notices.
( 02 · What we built )
An engine that reads the price first
We built Rozetpix to read price, compare-at price and stock from Shopify and print them into the store's frame. When a value changes, that image is printed again under a new file name and the feeds point to it.

How it works
02
Badges only when they're true
The discount badge prints only on a real discount, with the percentage worked out from the two prices and rounded down. The stock badge waits for your threshold.
03
One feed per channel
Meta and TikTok get catalogue XML, Google Ads gets CSV, each with the image sizes that channel expects.
04
Guards before publishing
If a new feed would drop below half of the last one, it isn't published; the previous feed stays live until you approve.

sizes printed per product
Every product is printed square, 4:5 and 9:16, so feed, Reels and Stories placements all get an image made for them.
