Frequently Asked Questions

Is my CSS uploaded anywhere?

No. Prettier runs as a WebAssembly module entirely in your browser. Your code never leaves your device.

Why is the first format slow?

The first format downloads the Prettier WASM bundle (~400KB). Subsequent formats on the same page are instant.
