Getting to Know Nightmare AI

Nightmare AI is an artificial intelligence based website (Artificial Intelligence/AI) is a free tool that functions to improve the quality of low-resolution images to make them cleaner and more detailed.
This tool is popularly used as an AI Image Upscaler because it can clear the image resolution with results that are not broken or blurry.
Nightmare AI uses Real-ESRGAN (Enhanced Super Generative Adversarial Network) technology that can analyze image details and generate additional pixels to maintain image quality.
So, Nightmare AI will work like an 'Image Detail Guesser', where a photo or illustration has low quality, then artificial intelligence (Artificial Intelligence/AI) will study the shape, color, texture and pattern in the image.
Later, the system will add details so that the image looks cleaner and sharper than the original version.
Therefore, the results will be better compared to improving image quality using ordinary editing tools.
Its main function is to increase image resolution up to High Definition (HD), 2K, 4K, 8K, and 16K.
This tool is also used for various types of images and specific formats such as JPG, PNG and WEBP.
This tool can also maintain the characteristic lines and colors of anime images when the resolution is increased so that the image is more natural.
Besides increasing resolution, Nightmare AI is able to clarify blurry images, reduce pixalated effects, improve facial details, remove objects or make vintage images look more modern.
In terms of use, Nightmare AI is very user-friendly because it is website-based and does not require installing an application.
So the user has to upload the image that they want to improve the quality of, then the artificial intelligence (AI) system will process it.
However, the limitation is that the results obtained may be slightly different from the original image.
In images that are very damaged or have little detail, artificial intelligence (AI) can also produce additional details that are less accurate.
In addition, several high-resolution features are available in the Pro package, so free users can only use the basic features.
So overall, Nightmare AI is a free photo enhancement tool that is easy for beginners to use.
Featured Features

Below are some features of Nightmare AI that you should know before using it, namely:
AI Image Upscaler
AI Image Upscaler is Nightmare AI's main feature to enlarge image resolution without breaking or blurring.
This feature uses artificial intelligence (AI) technology to analyze lines, textures, colors, patterns and details in images to produce extra details to make them more natural.
With the help of artificial intelligence (AI), the image will be enhanced to High Definition (HD), 2K, 4K, 8K and 16K without reducing the quality of the original image so that it looks cleaner and more detailed.
Restore Old Photo
Restore Old Photo is a Nightmare AI feature to repair old photos whose quality has decreased due to age, scanning process or damage.
Old photos are often blurry, faded, noisy, scratched, or low-resolution. With the help of artificial intelligence (AI), these details can be brought to light and cleaner.
During the restoration process, artificial intelligence (AI) will increase image sharpness, reduce blur, improve details and restore lost textures.
However, for photos that are really damaged or blurry, the results will not be the same as the original image.
AI Image Enhancer
AI Image Enhancer is Nightmare AI's feature for improving overall image quality. It will clarify blurry images, increase sharpness, reduce noise, improve lighting, enhance colors, and create cleaner images.
Image to Ghibli
Image to Ghibli is a Nightmare AI feature to turn ordinary photos into images that look like anime from Studio Ghibli.
Of course, artificial intelligence (AI) will retain the main object in the image, but will change the color, lighting, details and artistic nuances like animation from Ghibli.
Many users use it to change photos to look like Ghibli-style illustrations.
Cons:

Below are some of the shortcomings of Nightmare AI that you should know, namely:
Unnatural Face
The AI Image Enhancer feature results in faces that are too smooth, sharp, and different from the original photo.
However, with low-quality photos, artificial intelligence (AI) will change the shape of the eyes, nose, texture or hair until the results are unnatural.
The Risk of AI Hallucinations
Hallucinations in artificial intelligence (AI) systems are systems that produce information or details that are not present in the original image.
Blurry images will be given additional texture, new lines, details or elements from the results of artificial intelligence (AI) predictions.
The worse the image quality, the greater the risk of hallucinations appearing in the image.
Latency (Processing Time)
For large images or if the server is busy, you have to wait a few seconds for the process to complete.
Limited Features for Free Version
The free version of Nightmare AI has certain limitations such as limited credits, limited file size and limited total downloads.
Therefore, if users want to use the Pro features, they must subscribe first.
Inconsistent Results
Some enhanced images are clean, while others are more unusual or involve changes to the object. Therefore, the quality of the results will vary depending on the condition of the original image.
