# Convert images to text using JavaScript

You can convert images to text with Nutrient Web SDK.

Converting images to text is available when using [Web SDK](https://www.nutrient.io/guides/web.md) with [Document Engine](https://www.nutrient.io/guides/document-engine.md). For more information, refer to the [operational mode](https://www.nutrient.io/guides/web/about/operational-modes.md) guide.








First, make sure to [open the image from Document Engine](https://www.nutrient.io/guides/web/open-a-document/from-document-engine.md).

This feature requires the Image Documents component to be enabled in your license.

Next, detect the text in the image by running the `performOcr` operation:

```js

await instance.applyOperations([
  { type: "performOcr", language: "english", pageIndexes: "all" }
]);

```

This feature requires the OCR component to be enabled in your license.

Then you can extract the text using the [`NutrientViewer.Instance#textLinesForPageIndex`](https://www.nutrient.io/api/web/NutrientViewer.Instance.html#textLinesForPageIndex) method:

```js

const textLines = await instance.textLineForPageIndex(0);

```

To log all text in the image on the console, you can then run:

```js

textLines.forEach((l) => console.log(l.contents));

```

## Other languages

You can extract text written in languages other than English using the `language` parameter:

```js

await instance.applyOperations([
  { type: "performOcr", language: "spanish", pageIndexes: "all" }
]);

```
