# PagesApi.delete()

```ts
delete(pageIndex: number, options?: SignedDocumentOptions): Promise<void>
```

Deletes a page. Refused with `INVALID_ARGUMENT` when it would empty the document. Needs the `edit-pages` feature.

- Kind: method
- Since: 1.0.0

| Parameter | Type | Description |
| --- | --- | --- |
| `pageIndex` | `number` | Zero-based page index. |
| `options?` | `SignedDocumentOptions` | `{ invalidateSignatures? }`. |

Returns `Promise<void>`

Throws:

- `INVALID_ARGUMENT` — a page index out of range, or deleting the only page.
- `PAGE_ERROR` — the page tree is nested too deeply.
- `FEATURE_NOT_LICENSED` — the license lacks `edit-pages`.
- `DOCUMENT_CLOSED` — the document has been closed.
- `INVALID_STATE` — a certified document whose certification forbids it, unless `options.invalidateSignatures`; or a progressive document still downloading.

```ts
await doc.pages.delete(doc.pages.count - 1); // drop the last page
```
