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.

Features

Bria Increase Resolution upscales images while preserving the original content structure. Upload an image, choose a 2× or 4× 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

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.

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 2× when you need a moderate size increase.
• Choose 4× 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.
