How many PPI (Pixels Per Inch) should I use???

KillerPenguinStudios

Hello all,
I am creating images in Adobe Illustrator for my iPhone game and when exporting the images to PNG's I am trying to figure out what I should set the PPI (Pixels Per Inch) to to get the best results. Thanks in advance!

Thanks,

72ppi

Be careful, exporting directly out of Illustrator will usually give you a decimal value. I don't know why it does this, but when you export out of Illustrator, you should then open it in Photoshop, and look at the image properties. They will be something like 72.009ppi. If you leave it, the image will be blurry, so you need to change it back to 72ppi, and then save it again out of Photoshop.

Thank you so much for your comment! So would it then be best to go ahead and export it as a psd file then when done with it in Photoshop save it as a png?

What I do is, create the image in Illustrator, then export it as a .png. Open the .png with Photoshop, and go to - Image - Image size - And just change the ppi to 72 and save the .png. You don't have to save it as a .psd, it will let you just update the .png.

Hope that helps.

Good advice from @SlickZero; also another way, save the original file as psd or ai depending which program you've used, (so you keep any layers intact for future changes) then export it as png directly using Save for Web and Devices....

This way it'll save it as exactly 72ppi as well.
