Bria Increase Resolution

Bria Increase Resolution upscales images while preserving the original content structure. Upload an image, choose a or resolution increase, and optionally preserve transparent areas for images with an alpha channel.

Why Choose This?

  • Image upscaling
    Increase image resolution without regenerating the full image from scratch.

  • 2× and 4× scale options
    Choose 2 for moderate enlargement or 4 for a stronger resolution increase.

  • Content-preserving enhancement
    Improve image size while keeping the original subject, composition, and visual structure.

  • Alpha preservation
    Preserve fully and partially transparent regions when working with images that include an alpha channel.

  • Simple production workflow
    Upload an image, select the desired increase, and generate the upscaled result.

Parameters

ParameterRequiredDescription
imageYesInput image to upscale. Upload an image or provide a public image URL.
desired_increaseNoResolution increase factor. Options: 2 or 4.
preserve_alphaNoPreserve fully and partially transparent areas from the input image. When disabled, the output is fully opaque. Has no effect on images without an alpha channel.

How to Use

  1. Upload an image — Provide the image you want to upscale.
  2. Choose desired increase — Select 2 or 4 depending on the target output size.
  3. Configure alpha preservation optional — Keep preserve_alpha enabled when the input image contains transparency that should remain transparent.
  4. Submit — Generate the upscaled image and retrieve the output.

Pricing

Pricing is fixed at $0.04 per run.

OutputCost

Best Use Cases

  • Image resolution enhancement — Upscale images for higher-resolution use.
  • Design assets — Increase the size of graphics, illustrations, and creative assets.
  • Product visuals — Upscale product images for sharper presentation.
  • Marketing materials — Prepare higher-resolution images for ads, banners, thumbnails, and social media.
  • Transparent assets — Preserve alpha channels for logos, cutouts, stickers, and compositing workflows.

Pro Tips

  • Use clean, reasonably sharp input images for better upscaling results.
  • Choose when you need a moderate size increase.
  • Choose when the target layout needs significantly more pixels.
  • Enable preserve_alpha for images with transparent or semi-transparent areas.
  • Disable preserve_alpha when you want the final output to be fully opaque.
  • Avoid using extremely blurry or heavily compressed images when detail preservation matters.

Notes

  • image is required.
  • desired_increase supports 2 and 4.
  • preserve_alpha only affects images with an alpha channel.
  • When preserve_alpha is disabled, the output is fully opaque.
  • This model is best suited for images that are already reasonably clean and need additional resolution.

Increase Resolution API — Quick start

Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/bria/increase-resolution with your input as JSON. The endpoint returns a prediction id. Start polling the result endpoint around every 2 seconds, increase the interval for long-running tasks, and stop on any terminal status. On completed, read output values from data.outputs. Examples for Increase Resolution below.

HTTP example
set -euo pipefail

Increase Resolution API — Frequently asked questions

What is the Increase Resolution API?

Increase Resolution is a Bria model for upscaling, exposed as a REST API on WaveSpeedAI. Bria Increase Resolution upscales images with a method that preserves original content without regeneration, producing sharper, higher-quality output. Ready-to-use REST API, best performance, no coldstarts, affordable pricing. You can call it programmatically or try it from the playground above.

How do I call the Increase Resolution API?

POST your input parameters to the model's REST endpoint (shown in the API tab of this playground) with your WaveSpeedAI API key in the Authorization header. Submission returns a prediction ID. Poll the result endpoint starting around every 2 seconds, increase the interval for long-running tasks, and stop on any terminal status. The playground generates Python, JavaScript, and cURL examples for submitting requests and polling results. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/bria/bria-increase-resolution.

How much does Increase Resolution cost per run?

Increase Resolution starts at $0.04 per run. That figure is the base price — the final charge scales with the parameters you set in the form (output size, length, count, references, or whatever knobs this model exposes), so a higher-quality or larger output costs more than a minimal one. The exact cost for your current input is shown live next to the Generate button before you submit, and the actual per-call charge is recorded on the prediction afterwards.

What inputs does Increase Resolution accept?

Key inputs: `image`, `desired_increase`, `enable_base64_output`, `enable_sync_mode`, `preserve_alpha`. The full JSON schema (types, defaults, allowed values) is rendered above the Generate button and mirrored in the API reference at https://wavespeed.ai/docs/docs-api/bria/bria-increase-resolution.

How long does Increase Resolution take to generate?

Reported generation time on WaveSpeedAI is around 6 seconds per request. This is an estimate, not a latency guarantee; queue time and input settings can change the total wait. live status is visible in the prediction record.

Can I use Increase Resolution outputs commercially?

Commercial usage rights depend on the model's license, set by its provider (Bria). Check the provider's applicable terms and WaveSpeedAI's Terms of Service before commercial use.
