How to reduce the size (dimensions) of png?

Question

Design

Is there any way to reduce png without manual pixelart and nothing moves?
An example, the original image (70x70):

Here it is reduced to 35x35 in fsh in the most appropriate "bicubic clearer" mode:

Visually white stripes have become of different thicknesses. It's even worse in other modes. The only way to reduce without information loss is by a factor of 2 in the "neighbor" mode, but this is only suitable for cases in a vacuum

Answer 1

Try to enlarge the image first, and then reduce it to the desired size.
I also join Sergey 's advice - use a vector, Luke.

Answer 2

Here you need to connect your knowledge in the field of mathematics.
Your image: 70px x 70px made up of 16 15px x 15px squares spaced 2px apart.
When you reduce the image by 2 times (35px x35 px) - 16 squares of 15px are also divided by 2.
15/2=7.5px
2/2=1px
Your image looks blurry due to the fact that the division did not result in an integer and pixels did not stand on the pixel grid.
To avoid this, you should initially keep in mind the possible options for scaling the icon.
For example, a 70px x 70px icon consisting of 16 squares with a size of 16px with a spacing of 2 px - with a 2x reduction, it gives a clear picture because:
16/2=8px
2/2=1px
A great way is to use .svg. Vector format that stays sharp when scaled.

Answer 3

My advice works for all formats, both raster and vector. When rendering a vector or reducing a raster, use the correct monitor gamma (2.2 for Windows, now, as far as I know, Mac has also switched to it).
Here we have two colors: (0.5, 0.5, 0.5) and (1, 1, 1). How many times is the second brighter than the first? doubled? No, 2^2.2 times. Therefore, a strongly blurred (blurred with gamma 1) line comes out thinner and not so blurry.
