Sprite definition in web build

Unity Engine
1

Hello!

I have a problem with sprites definition.

Sprites in the new build for Web lose quality. (In the build for OS X everything is good with quality)

Here are examples of the old and the new version:
old version - good quality - http://goo.gl/uGTExc
new version - bad quality - http://goo.gl/Ur81O5
to see the difference you need to click on the shield and run level

In the new version I add a couple dozen sprites. Settings do not change. Older sprites do not change.

Why could I lose quality of image?

Please help, I need to make last version build for competition, but I can’t show version with low quality of image. It’s awful
