Question 1

How does AI image upscaling work?

Accepted Answer

Our AI upscaler uses Real-ESRGAN, a neural network trained on millions of images. It analyzes your photo and generates new pixel detail that doesn't exist in the original, producing genuinely sharper images rather than simply stretching pixels.

Question 2

Is the image upscaler free?

Accepted Answer

Yes, HiResolutionPhotos is completely free to use. There are no sign-ups, no watermarks, and no hidden fees. Upload any image and download the enhanced version instantly.

Question 3

What image formats are supported?

Accepted Answer

We support JPG, PNG, and WebP formats. The maximum file size is 10 MB. Your upscaled image is returned as a high-quality PNG.

Question 4

How long does upscaling take?

Accepted Answer

Most images are processed in under 30 seconds. Processing runs on dedicated NVIDIA GPUs for fast results. Larger images may take slightly longer.

Question 5

Are my photos stored or used for training?

Accepted Answer

No. Your images are processed and deleted immediately after the upscaled version is generated. We never store, share, or use your photos for AI training.
