The problem
Food waste starts with air.
Berries go soggy. Crackers go soft. Freezer burn sneaks in. JarSeal pulls the air out so freshness lasts longer.
Soggy berries by Wednesday
Remove oxygen from fridge jars so produce keeps its color and crunch longer.
Stale snacks in the pantry
Seal crackers, flour, and coffee in the jars you already have — no plastic bags.
Freezer burn on leftovers
Vacuum-seal soups, stews, and prepped meals before they hit the freezer.

How it works
Three steps to a tighter seal
01
Fill your jar
Use any regular or wide-mouth mason jar you already own — leftovers, berries, dry goods.
02
Seat the lid
Place a JarSeal lid (or compatible flat lid) and rest the cordless pump on top.
03
Press & seal
One button pulls the air out in seconds. Hear the click, store with confidence.
Our story
Built after one too many wasted berries.
JarSeal started in a small Austin kitchen after we watched premium produce wilt in a week. We wanted a sealer that worked with jars we already owned — cordless, quiet, and simple enough for weeknight leftovers.
Today every kit is designed around real pantry habits: bulk beans, salad jars, freezer soups, and the crackers that always go soft.
