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.
