# Enhance Image

[**Try out this capability in Bria's sandbox**](https://platform.bria.ai/image-editing/enhance-image)
**Description**
Regenerate an image with sharper textures and richer details while doubling resolution, up to 10 megapixels output.
Note: this endpoint only supports async response mode - the API immediately returns a status URL to track progress.
**Content Moderation**
This endpoint includes granular content moderation controls to ensure safe usage across all stages of processing:
- **Input Image Moderation** – Scans the uploaded image and stops processing if inappropriate or restricted content is detected.
- **Output Image Moderation** – Evaluates the generated image and blocks the response if it violates safety guidelines.

Note: use [Increase Resolution](https://docs.bria.ai/image-editing-v2/v2-endpoints/increase-resolution) route to increase resolution without impacting details.

Endpoint: POST /enhance

## Header parameters:

  - `api_token` (string, required)

## Request fields (application/json):

  - `image` (string, required)
    The source image to be handled by the API.
Supported input types:
- **Base64-encoded string**
- **URL** pointing to an image file that is publicly accessible and available at the time of processing.

Accepted formats: **JPEG**, **JPG**, **PNG**, **WEBP**.

  - `seed` (integer)
    Optional seed for controlling generation randomness. You can recreate the same result in the future by using the same seed with the same input parameters.

  - `preserve_alpha` (boolean)
    Controls whether the alpha channel values from the input image are retained in the output, if the input includes an alpha channel.

  - `visual_input_content_moderation` (boolean)
    When enabled, applies content moderation to input visual.
Expected behavior:
- Processing stops if the image fails moderation.
- Returns a 422 error with details about which parameter failed.

  - `visual_output_content_moderation` (boolean)
    When enabled, applies content moderation to result visual.
Expected behavior:
- If the modified image fails moderation, returns a 422 error.

  - `webhook_url` (string)
    Optional URL for receiving the result via webhook when the async job completes. See [Webhooks](https://docs.bria.ai/webhooks).
