AI Image Upscaler

GPT Image 2Real-ESRGANFree AI enhancement

Enhance JPG, PNG, and WebP images with GPT Image 2 cloud AI or private local Real-ESRGAN.

Source image
Choose an image
or drag and drop a JPG, PNG, or WebP

GPT Image 2 enhances detail in the cloud.

Free cloud quota: 10 images/hour and 20/day per anonymous user. Images are uploaded only when Cloud AI is selected.
How it works

Choose GPT Image 2 for cloud generative enhancement or Real-ESRGAN for private 4x processing in your browser.

GPT Image 2 enhancement
Cloud AI can restore natural-looking detail, reduce artifacts, and improve perceived clarity.
Local image processing
Local AI keeps the selected image on this device during upscaling.
Cloud or local
Use the recommended cloud mode for generative quality or switch to local mode for maximum privacy.
Two AI models
GPT Image 2 handles cloud enhancement while Real-ESRGAN provides deterministic local 4x output.

How it works

Three steps to finish the browser workflow.

Frequently asked questions

Find quick answers about privacy, browser support, exports, and what to try when a file is heavy.

Does this tool use a cloud provider?

Yes. This workflow needs AI processing outside the browser, so the page uses a provider-backed task flow instead of local-only processing.

Will the result have a watermark?

No. ArtPlayer does not add watermarks to the downloaded result.

Do I need an account?

No regular account is required, but the tool may use short-lived sessions and quota checks to keep the service available.

Why can processing take time?

Provider-backed work depends on file length, queue capacity, network conditions, and the model or service used for the result.

What can make a cloud task fail?

Tasks can fail when the file is too large, the format is unsupported, the network drops, or the provider is temporarily unavailable.

Does image upscaling run in the browser?

Yes. The image is processed on this device with browser AI runtime support after the model loads.

Why does the first run take longer?

The first run downloads the Real-ESRGAN model and caches it in Cache Storage for later visits.

Can I upscale an image without uploading it?

Yes. The image upscaler runs in the browser when the required runtime is available.

Which images work best?

Clean images with moderate resolution usually upscale better than very noisy, tiny, or heavily compressed sources.
