You took the perfect snapshot, but the photo is too small to immediately see all the details of the subject? If the picture is now enlarged with a program, the quality often suffers. Downsizing is not a problem. In this tipps + tricks article, we show why that is and which tools still help.

Enlarging images without loss of quality - is that even possible?

The individual color values ​​of an image are defined by pixels. These color values, which are also referred to as image cells, are used to record the surface elements required for recording or displaying a color value. For example, if you have an image with 4 x 4 square pixels and enlarge it by a factor of 100, you will receive an image with a size of 400 x 400 pixels. That the quality of the result suffers is inevitable.

As a result, enlarged photos often appear spongy and of insufficient quality. Reducing images is of course unproblematic due to the pixel density. The solution for the loss of quality: Intelligent algorithms that adapt the pixels when enlarged and supplement them accordingly. In the meantime, several applications have become established for this. Either try online through tools like imageenlarger.com or use an offline solution like SmillaEnlarger. In our picture gallery we show you how you can use it to adjust the size of the picture:
