# Barcode Generator
> Generate various types of barcodes including QR Code, Code 128, Code 39, and more.
## Input
| Name | Description | Required |
| :---------------------- | :--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | :------- |
| **Barcode Value** | Set the string value to encode inside the barcode, must be in a string format. | Yes |
| **Barcode Type** | Set the barcode type to be used. | Yes |
| **Decoration Image** | Enter the image URL to insert as a logo inside the QR Code. Only **PNG**, **JPG**, or **JPEG** formats are supported. | No |
| **File Name** | File name for the generated output, the input must be in string format. | No |
| **Generate Inline URL** | Set to true to return results inside the response. Otherwise, the endpoint will return a URL to the output file generated. | No |
| **Custom Profiles** | Use JSON to customize PDF processing with options like output resolution, OCR settings, text extraction methods, encryption, and image handling. Check our [Custom Profile](#custom-profiles) section to see all available parameters for your current endpoint. | No |
## Custom Profiles
You can set additional options for the operation used in the PDF.co node by using **Custom Profiles**. A custom profile is a string in **JSON-like format** containing predefined parameters.
Here’s an example of a Custom Profiles input:
```
{ "outputDataFormat": "base64" }
```
With this input, the PDF.co operation will return the output in `base64` format. You can find the list of available parameters for customizing profiles in the PDF.co operation documentation below:
You can use any regular API parameter from the [API Reference](/api-reference)within n8n using the `std_params` feature in profiles. The `std_params` enables the definition of regular API parameters in a JSON format, See [Standard Parameters](/api-reference/profiles#standard-parameters) for detailed documentation and examples.
| Parameter | Type | Default | Description |
| :------------------------ | :------ | :-------- | :----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `outputDataFormat` | string | - | If you require your output as `base64` format, set this to `base64` |
| `Angle` | integer | `0` | See [**profiles.Angle**](https://docs.pdf.co/api-reference/barcode/generate#profiles-angle) |
