I want to put a footer in an email. The footer will be 650px wide, and in PNG format.

I am designing the footer in Adobe Illustrator CC. When i go to export if i export at 72DPI the outputted file is 650px wide. But the artwork is not crisp.

If i output at 150DPI the artwork is crisp, but the outputted file is 1313px wide.

Is there a way i can set the art-board to export at 650px width, but 150DPI ?

    DPI/PPI does not exist in email or on the web. – Scott Mar 17 at 21:26
  • Doesn't the 150 ppi (as dpi is called nowadays) image just look more crisp because it's bigger and therefore have more details? You can't show more pixels per inch than the screen is capable of. – Wolff Mar 17 at 21:32

  • Thanks @Scott is there any way to get SVG / EPS like crisp ness in an email footer graphic ? Without having to make the images huge ? – sam Mar 17 at 23:04

    I personally think any image in a communication email footer is superfluous. Images are for sales emails, otherwise they should not be part of the email as anything other than attachment. There's no point in ballooning the file size of communication emails with unnecessary images. If you must then SVG is folly.. many email applications won't support SVG at all. Truth is.. anyone using plain text email will see any image as an attachment anyway. – Scott Mar 18 at 0:32

As you noticed, every ppi you change, it will be altered in email view, because the email always tries to show you the image as 72dpi. If you increase the ppi, it will be bigger. The Illustrator is vector based and dpi independent.

Note: ppi(Adobe) and dpi are the same.

The solution is to play with the Anti-aliasing methods while in the PNG options export dialog, and see what is best for you.

I'm showing two examples below.

  • Erm the email app ins showing 72ppi is just showing each pixel as they were presented. Just ignoring your settings entirely. – joojaa Mar 18 at 20:47

create a new photoshop document at 150dpi and 650px wide, paste your artwork as pixels in photoshop. Save as jpeg.
