OK I know that vectors resize better than bitmaps. For a final project I have to build a website that has christmas cards and stuff like that.

I need to put snowflakes in the background.

My question is, if I do the snowflakes as vectors will they resize the way vectors do on the web site? Or does being vectors instead of bitmaps only matter when your resizing in photoshop or illustrator?

You can make a vector any size then resize it all you want and it will retain its clarity (not become rasterized). you can then make it whatever size that you want and export it as a .jpg or .gif (I'd say a .gif if you need a transparent background, jpg if not)

yea but what I was wondering is if I made a vector based snowflake and saved it as a jpeg, does the jpeg retain the vector qualities? So if the background on a webpage is stretched will it retain its clarity no matter how much its stretched?

JPEG will retain most of the quality vector images give over raster. Just don't compress too much if you don't want a grainy image. If it's stretched it will act just like any other jpeg image and won't keep its clarity like it would in the actual program. You need to save the image to be as close to however big you need to use it.

aight thanks
