Spristes bad quality

I used high resolution png images that i create in Illustrator but when i export it to Unity saving as web, it has bad quality i use 1024 max and 16 bit format but it doesnt has a very good quality as i want, what should i do? How do you make your sprites and exporting without problems using PNG images?

When importing check to see what Filter Mode your using. If you want that pixel-y feel choice “Point”.

Also for your format, picking “Truecolor” might give you better results.
