How does bigjpg compare to other tools?

With other software and tools, such as PS, an enlarged image can still look fuzzy and have visible blur as well as noise. Our product uses neural networks with a special algorithm adjusted specifically for the images' lines and color. This makes the resulting image much higher quality. Colors are well kept, and there is almost no 'glitter' or doubling visible. More importantly, the noise, which seriously influences quality, cannot be seen in the resulting images.
