## Properties

### brotli?

```ts
optional brotli?: boolean;
```

```ts
false
```

optional gzip?: boolean;
```

Defined in: [src/features/report.ts:37](https://github.com/rolldown/tsdown/blob/eb40c95efdf7f98d0aa7b0178a3b7322986bd419/src/features/report.ts#L37)

Skip reporting compressed size for files larger than this size.

#### Default

```ts
1_000_000 // 1 MB
```

***

```

Defined in: [src/features/report.ts:59](https://github.com/rolldown/tsdown/blob/eb40c95efdf7f98d0aa7b0178a3b7322986bd419/src/features/report.ts#L59)
