Pickling preserves food because the acidic brine discourages the growth of spoilage microbes.
The longer version
Most spoilage organisms struggle in an acidic environment because a low pH disrupts the enzymes and transport systems their cells depend on. A brine of vinegar or salted water that ferments into lactic acid pushes the food below the range where spoiling microbes can multiply readily, and dissolved salt adds osmotic pressure that pulls water out of any cells present.
Fermented pickles develop their sourness gradually as salt-tolerant bacteria convert sugars into acid, while quick pickles simply soak in vinegar. Either way, the acid is the preservative rather than the jar. Heat sealing and cold storage extend the effect further by removing or slowing whatever remains.
