# Make Text Searchable

> This method converts scanned PDF documents (where pages are fully or partially made from scanned images) or image files into a text-searchable PDF. It runs OCR and adds an invisible text layer on top of your document that can be used for text search, text indexing, etc.

## `POST /v1/pdf/makesearchable`

<Warning>
  This endpoint uses **300 DPI rendering** by default, which may significantly increase output file size-especially for image-heavy PDFs. To reduce file size, set a lower rendering resolution by using the [`profiles`](/api-reference/profiles) attribute in the request body. For example, to set the rendering resolution to 72 DPI, use:

  ```json theme={null}
  { 'RenderingResolution': 72 }
  ```
</Warning>

## Attributes

<Note>Attributes are case-sensitive and should be inside JSON for POST request. for example: `{ "url": "https://example.com/file1.pdf" }`</Note>

|     `RotationAngle`                | integer                       | *No*     | -         | Use manual rotation to handle PDFs with vertically drawn text. Normally, OCR automatically detects page rotation in PDFs and extracts text accurately. However, in some cases, the PDF might not have an actual rotated page  ---  Rather, the text itself is drawn vertically. In such scenarios, auto-detection may fail. You can use this parameter to manually set the page rotation. The available angles are: `0`, `1`, `2`, `3`.                                                                                                                                            |
|     `LineGroupingMode`             | string                        | *No*     | None      | Controls line grouping in PDF text extraction. Modes: `None` (no grouping), `GroupByRows` (merge rows if all cells align), `GroupByColumns` (merge cells by column), `JoinOrphanedRows` (merge single-cell rows to above if no separator).                                                                                                                                                                                                                                                                                                                                         |
|     `ConsiderFontColors`           | boolean                       | *No*     | `false`   | Controls whether font colors should be considered when detecting table structure and merging text objects during PDF extraction. Set to true to consider font colors.                                                                                                                                                                                                                                                                                                                                                                                                              |
|     `DetectNewColumnBySpacesRatio` | string                        | *No*     | 1.2       | Controls how spaces between words are interpreted for column detection in PDF text extraction. It defines the ratio of space width that determines when text should be treated as being in separate columns.                                                                                                                                                                                                                                                                                                                                                                       |
|     `AutoAlignColumnsToHeader`     | boolean                       | *No*     | `true`    | Controls how columns are detected and aligned during table extraction from PDF documents. It affects both table structure detection and text extraction with formatting preservation. Set to true to automatically align columns to the header row. When set to true (default), the row with the most columns is used as the header, and all other rows are aligned to this structure --- ideal for well-structured tables. When set to false, columns are analyzed independently across all rows to build the structure, which works better for inconsistent or irregular tables. |

## `Example` Response

<Note>To see the main response codes, please refer to the [Response Codes](/api-reference/response-codes) page.</Note>

```json theme={null}
{
  "url": "https://pdf-temp-files.s3.amazonaws.com/a0d52f35504e47148d1771fce875db7b/result.pdf",

  "error": false,
  "status": 200,
  "name": "result.pdf",
  "remainingCredits": 99033681,
  "credits": 35
}
```

<Note>
  **Inconsistent URL Encoding in cURL Output:** When using cURL to make API requests, the output JSON may show URL characters encoded as Unicode escape sequences. For example, the ampersand character (`&`) may appear as `\u0026` in the cURL output. This is normal JSON encoding behavior and does not affect the validity of the URL. The URL will function correctly when used, as JSON parsers automatically decode these escape sequences. If you're parsing the response programmatically, your JSON parser will handle this conversion automatically.
