How to Increase Resolution of an Image with and without Photoshop

How can I increase the resolution of an image without losing quality?

Once upon increasing the image resolution to high (ultra HD, 4K or 8K), you may encounter a situation where it looks blurry or pixelated. In the past years, there was no good way to resize a smaller image into a larger resolution with the quality enhanced, and the traditional ways could increase the resolution of a digital image file, but the image quality was lost.

Nowadays, so many tools are featured to increase resolution while boosting the visual quality, among which the AI Image Upsaler or Enlarger based on artificial intelligence (AI) and machine learning (ML) come in handy. With Super Resolution adopted in AI Image Upscaler or Enlarger, you can dramatically increase image resolution while without sacrificing the image quality, or even with more details of pixel recovered, in a proper and naturalistic way. Adobe Photoshop and Adobe Photoshop Lightroom also have features that can help you increase the resolution of an image while upholding visual quality. Let's try to use AI Image Upscaler (desktop software and web application) and Adobe Photoshop to increase the resolution of an image like a magic.
