It's true that artificial intelligence can generate images with just a few words, as demonstrated by tools like DALL-E and Midjourney, but it can also dramatically improve the quality of pixelated images, regardless of whether they are old or new. This means, for example, that you can restore old family photos that have been around for decades and make them look as if they were taken recently. Today, we share with you 5 online tools that can be used directly through the browser without the need to download any software. Moreover, they are free and do not watermark the images, and most importantly, they are incredibly easy to use and do not require creating an account; you simply upload the image you want to enhance, and AI takes care of the rest.
Enhancing Image Quality with Artificial Intelligence
Before we review the tools, we need to first standardize the terminology and understand what is meant by "image quality enhancement." Essentially, digital images consist of small units called pixels. When the number of these pixels is small, the image quality is poor, and vice versa. This is because each pixel contains information responsible for highlighting certain details. Therefore, when we say "enhancing image quality," we mean increasing the number of pixels in the image.
Traditionally, methods for enhancing image quality involve averaging the nearest 4 pixels to generate a new pixel unit, and if it's more advanced, the number of pixels may reach 16. However, with artificial intelligence, the approach is different. AI tools can evaluate all the pixels at once, focusing on patterns rather than numbers because they are trained on vast amounts of data. Below are the best examples of online tools for enhancing image quality with AI.
#1 AnyRec Tool

| Anyrec Image Upscaler |
The free version of most tools of this kind is limited to enhancing images up to 4 times. However, the free AnyRec tool is different; it offers enhancement of up to 8 times without losing any details, all in a matter of seconds. It's worth mentioning that the enhancement options range from 2x to 8x.
This tool supports various image formats such as JPG, PNG, and JPEG, and its workflow is incredibly easy like the rest of the tools. Simply go to the official website of the tool or click link bellow, click on "Upload Photo," select the image, and wait for it to be uploaded to the website. The enhancement will be done directly with AI. You can choose up to 8x enhancement as mentioned, and you will see the differences in the instant preview that appears before you. If you like the result, you can save the image by clicking on "Save."
#2 iLoveIMG Tool
 |
| iLoveIMG AI Upscaling Tool |
This free and simple tool offers two basic enhancement options: 2x or 4x. Like the previous tool, you can upload the image, choose the enhancement strength, and see the results for yourself. What's great here is that you can enhance up to 3 images at the same time and customize the settings for each of them separately.
It's also important to note that this tool may not provide satisfactory results on the first try, but that usually changes with the second attempt. Also, iLoveIMG tool is indeed free, but the number of enhancements is limited, and you need to log in with your Google or Facebook account. If you like its performance and want unlimited modifications, you can subscribe to the paid version, which costs only $4 per month and offers greater enhancement capabilities and eliminates annoying ads.

#3 Image Upscaler Tool

| Img Upscaler Tool |
The third free tool allows you to enhance image quality for free up to 4 times. Its interface is simple, and it supports JPG and PNG images. While its results may not be as satisfying as the previous tools, from a distance, the enhanced images look great. However, upon closer inspection, you may notice some distortions or artifacts here and there. If you're a content creator and want to use an image as an icon or thumbnail, the free Image Upscaler tool may suffice. Otherwise, it may be better to use the above two tools. Like the iloveimg tool, this tool offers a limited free version of 20 images per month. However, it also offers a paid version if you want more enhancements, specifically 10 images for $9, which many may find excessive.
#4 Upscale.Media Tool
 |
| Upscale.Media AI Image Upscaler Tool |
If you don't want or can't use any of the mentioned tools for any reason, you can try Upscale.Media. Honestly, it's the least in terms of quality, although it can enhance images up to 4 times. The images produced by this tool are clearly flawed, and artificial intelligence in it is not the best. However, we must remember that it offers a free package - albeit limited - and it should be noted that the first attempt usually is not the best. You can try the tool, which also allows you to enhance the quality of 3 images at once. If you like it, you can get more enhancements for $10 a month. The enhancement strength can reach up to 4 times.

#5 Pixelcut.ai Tool
 |
| Pixelcut Free AI Photo Editor |
Although the enhancement power in this tool is limited to 2x only, the quality of the enhanced images using it surpasses the previous tool to some extent, from the first attempt. However, this doesn't mean that they are flawless or that the images produced won't appear as if AI has intervened when examining the details. Therefore, the fewer flaws the image to be enhanced has, the better the results of this tool. As we're used to, the results of this tool are better the second time than the initial results. Pixelcut.ai offers a limited free version with a certain number of attempts. However, with a $10 monthly subscription, you can get an unlimited version with enhancement strength of up to 4 times.

Conclusion
In summary, we can say that the first tool on the list, AnyRec, is the best choice. It's completely free, and its results are fantastic. While it's not perfect, and a reviewer may detect the intervention of artificial intelligence, this is unlikely in most cases. We mustn't forget that AI evolves every day, and things will improve significantly in the near future.
