Image Upscaling Features

Built for quick quality improvements without opening a professional editor.

Detail-Aware Upscaling

The AI image upscaler reads the subject and scene before rebuilding details, so the result looks sharper without the flat, stretched look common in basic resize tools. It is useful for old website images, small social media assets, low-resolution AI outputs, and photos that need more clarity before publishing.

AI Image Upscaler FAQ

Common questions before using the image upscaler.

What is an AI image upscaler?
An AI image upscaler enlarges an image while using a model to rebuild missing detail. A normal resize tool only stretches existing pixels, which often makes the image blurry. AI upscaling can improve edges, textures, and clarity so the final image looks more usable for websites, social media, product previews, and creative projects.
Can I upscale images to 4K?
Yes, the automatic enhancement instructions target HD and 4K-style clarity. The final result depends on the original image quality, subject complexity, and selected model. A clearer source image usually produces a cleaner 4K-ready result.
Does it work for portraits?
Yes. Portraits are a common use case for AI upscaling. You can ask for sharper facial details, natural skin texture, clearer eyes, and reduced blur. Avoid asking for heavy beautification if you want the person to remain close to the original image.
Can I upscale AI-generated images?
Yes. AI-generated images often look good at a glance but may be too small for publishing. Upload the generated image and the page will automatically request cleaner detail, preserved composition, sharper edges, and natural texture.
Will the upscaled image stay exactly the same?
AI enhancement may rebuild details, so tiny textures or background elements can change. This page uses conservative enhancement instructions to preserve the original composition and improve quality without intentionally turning it into a new image.
What file types can I upload?
The upload area supports common image formats used by the theme workflow, including JPG, JPEG, PNG, and BMP. For best results, use a clean source image without heavy compression artifacts. WebP support depends on the browser and upload configuration.
How many credits does upscaling cost?
Credit usage is controlled by the selected AI model. Different models may have different prices and output quality. Check the model selector in the creation panel before generating so you know the estimated credit cost for the current task.
Is this better than browser-only resizing?
Browser-only resizing is fast and private, but it cannot invent detail. AI upscaling is better when you need a visibly sharper image, cleaner subject edges, or improved texture. Use browser resizing for simple dimensions, and AI upscaling when quality matters.
Do I need to write extra instructions?
No. The upscaler adds the enhancement instructions automatically, including high-resolution output, original composition, sharper details, reduced blur, natural texture, and clean HD quality. You only need to upload the image and choose a model.
Can I use the result commercially?
Commercial use depends on the image you upload, your rights to the source material, and the model terms. If you own the original image or generated asset, the upscaled result is generally suitable for your own publishing workflow. Avoid uploading copyrighted images you do not have rights to use.
