Increase Resolution

Increase Resolution

Request

Try out this capability in Bria's sandbox

Description

The Increase Resolution Route is used to upscale the resolution of any image.

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.

Constraints

The Bria API currently supports only JPEG and PNG files in RGB, RGBA, or CMYK color modes. When the file is of a different type or color mode, the status code 415 will be returned.

It's possible to increase the resolution of an image up to a total area of 8192x8192 pixels.

Unlike the Enhance Image route, this endpoint does not add new details — it increases resolution using a dedicated upscaling method that preserves the original image content without regeneration.

Headers
api_tokenstringrequired
Bodyapplication/jsonrequired
imagestringrequired

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.

preserve_alphaboolean

Controls whether the alpha channel values from the input image are retained in the output, if the input includes an alpha channel.

  • When true: The output image maintains the original transparency of fully and partially transparent pixels.
  • When false: The output image is fully opaque.
  • Has no effect if the input image does not include an alpha channel.
Default:true
desired_increaseinteger

The resolution multiplier. The possible value are 2,4. It's possible to increase the resolution of an image up to a total area of 8,192x8,192 pixels.

Default:2
syncboolean

Specifies the response mode.

  • When false (default), the request is processed asynchronously: the API immediately returns a status URL to track progress.
  • When true, the request is processed synchronously: the API hold the connection open until the proccess is complete and then returns the final image URL in the response.
Default:false
webhook_urlstring, (uri)

Optional URL for receiving the result via webhook when the async job completes. See Webhooks.

visual_input_content_moderationboolean

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.
Default:false
visual_output_content_moderationboolean

When enabled, applies content moderation to result visual.

Expected behavior:

  • If the modified image fails moderation, returns a 422 error.
Default:false
