How to Increase Resolution for Picture By Top 3 Online Image Enhancers

We download images from the Internet every day but we might get the thumbnail or preview images with lower resolution. These kinds of low-quality images will not be as effective as they are portrayed, no matter how charming they are. For example, setting these images as wallpaper or sharing them on your social media.Everyone hopes that their photos can be of higher resolution to satisfy themselves when sharing photos on the Internet and in daily use. This provides for a better presentation of pictures and attracts others’ attention and discussion. That’s why it is essential to learn how to increase the resolution and fix the low-resolution images. Read this post and it shows the easy techniques to enhance images.

Why Choose AI Image upscaler

If you do not have high-resolution images

  • Make high-resolution adjustments with a photo editor
  • Use Image upscaler website or software

Using traditional photo editors to enlarge the size of the picture may not live up to your expectations. Because these photo editors, like Photoshop, cannot generate pixel details that do not exist and fill the gaps to increase the size. So, in this post, I recommend AI image upscaler.AI image upscaler uses artificial intelligence to enlarge and improve image quality by filling in the gaps with the best estimates. AI image upscaler is much more precise than a photo editor.

How AI Image Upscaler Tools work.

1. Artificial Intelligent detection of fill-recovered details for resizing

AI Image Upscaler tools improve photo quality by restoring and filling in lost pixels, colors, textures, and other details with intelligent detection. These tools use the advanced image-processing technology called Super-Resolution(SR) based on a deep convolutional neural network(CNN). SR could detect the difference between LR images and HR images, yet demonstrates the restoration quality automatically. These tools are easy to operate, novice-friendly, and have one click to get your high-definition pictures. For more detailed information about this kind of technology, you can refer to here:

2. Enhance photos for better color matching

When you increase the resolution of your photo, AI Image Upscaler will enhance your photo and get a matching color balance. Photos obtain better contrast and colors to optimize visuals. You just need to compare the new high-resolution photo with the previous photo and you will be surprised.Of course, the Image upscaler can also optimize portrait photos and automatically refine faces. Just upload a picture simply, one-click operation.

What Resolution Should Your Images Be?

Images have a wide range of uses in life. Suitable resolutions in different scenes can present better visual effects. Therefore, not all photos have higher resolutions and better ones. Adjustments should be made according to the way of use and the scene.For example, for screen images and printed images, from the screen images aspect, we also need to consider the pixel size of the monitor, TV, projector, or monitor. From the printing images aspect, using the pixel dimensions of the image is the real determinant of image size and quality.The following parameters are for reference only and hope to help you.

Pixel Size
Preferred File Format
Approx. File Size

1. What is a High-Resolution Picture

Image resolution is often described in terms of PPI, which refers to how many pixels per inch an image displays. HD picture resolution is also higher, higher resolution means more pixels per inch (PPI), which produces more pixel information and creates high-quality, clear images with a better visual experience.According to the previous section, we know that high-definition pictures need to match the best resolution according to specific usage scenarios, and the required resolutions for different purposes are also different. For example, screen images like avatars and wallpaper background walls. These are all different resolutions. Choosing the appropriate resolution to match our usage scenario.

2. What are the elements affecting the resolution of Digital Image

The resolution is linked to the image sensor and the pixels of the digital camera. The quality and the number of pixels of the image sensor determine the resolution of the digital image.A pixel(px) is the smallest unit that forms an image signal on an image sensor chip, that is, one photosensitive point. The higher the number of pixels and the larger the size of a single pixel, the higher the resolution and the clearer the image.Here are some resolutions for images posted on the web commonly.1920*1080: HD Suitable for graphics work and large-screen monitors, high-pixel visual effects are better and more vivid.1280*720: HD-ready This resolution is suitable for regular work on a computer monitor, and for viewing photos and videos. Suitable for watching high-definition or lower-frequency videos.1080*1080: Common photo size used on the website the appropriate normal size to better display the picture.


The above are some of the knowledge and commonly used picture tools for improving and increasing the resolution. You can choose the appropriate resolution according to your situation and the usage of pictures. The tools you choose according to your preferences will help you upgrade pictures efficiently and quickly.
