How to increase the resolution without losing quality?

Question

Adobe Photoshop

Tell me if there are methods that allow you to increase the resolution without losing quality? (for example, so that the picture is 5 times larger)
Maybe some chips in Photoshop, or maybe some other programs ...

Answer 1

1. Launch Photoshop and open a low resolution image
2. Choose Image > Image Size, multiply the width and height pixels by the scale you want to achieve.
3. Then don't forget to click Resample > Preserve Details 2.0
4. Choose to reduce noise or not based on original image (optional)
5. Click OK
