I want to retexture models, but it looks like i need them in 256 color palette. So i convert them with Paint, but it loses it quality and looks awfull. How do i convert the pictures without losing quality?

You can't. If you used more than 256 colors and you need a 256-color palette you are going to lose quality, there is no way around that unfortunately (except perhaps by using lots of 16x16 pixel textures instead but that would require more than a simple texture swap).

What you can do is use another editor that does a better job, but you will still loose some quality - that's what we get for still modding these old games. Try GIMP or perhaps Photoshop.

As Oskar already said, you'll always have some quality loss, but the Paint program that comes with Windows is terrible for color conversions like this, pretty much any tool will produce better results. You could use a powerful image editor like GIMP or Photoshop, or a more advanced Paint-like program like Paint.NET, but a tool like Irfanview is also a good choice if you just need to convert some existing images.

Here's a comparison I did a while ago (this was for textures, which require the same conversion). As you can see, with Irfanview you'll hardly see any quality loss even with images that contain a lot of different colors and gradients. For 'easier' images like the cobblestone texture, any half-decent tool is good enough already:

a bit late but i use photoshop's "save for web" tool to export 256 color images, as it can make a pallete specifically designed for the image you provide
