This might be a stupid question, but I have been asked to make a skyscraper ad for a website and they want it sent in jpeg format.
I designed the ad in illustrator and saved it as an ai file. Since I have no coverter to change ai to jpeg I saved it as a high quality pdf and saved that as a jpeg.
My problem: when I created the document the ai file was 300px X 250px but the jpeg turned out to be 834 x 695
I don't know what happened? How would the size of the document change?
