In the work bowl of a food processor, pulse strawberries until smooth. Strain through a fine-mesh sieve into a bowl, pressing with a spatula to separate seeds. Discard seeds.
Add vinegar, sugar, salt, and pepper to strawberry purée, whisking to combine; whisk in oil. Serve immediately, or cover and refrigerate for up to 1 day.
