Reducing application file size

Here are some tips on reducing the file size of your IPA file:

  • Check background bitmaps to see that they are the right size (not larger than needed).

  • Check to see if any extra fonts are being embedded.

  • Look at PNG assets for alpha channels and remove them if they are not needed. Use a utility like PNG crunch to reduce the size of PNG assets.

  • Convert PNG assets to JPG assets, if possible.

  • Consider compressing sound files (by using a lower bit rate)

  • Remove any assets that are not used.
