About
Convert a Blob to a Uint8Array
The Blob class provides a number of methods for consuming its contents in different formats. This snippets reads the contents to an ArrayBuffer, then creates a Uint8Array from the buffer.
```ts theme={"theme":{"light":"github-light","dark":"dracula"}} const blob = new Blob(["hello world"]); const arr = new Uint8Array(await blob.arrayBuffer());
