: How to improve image detail quality for mobile apps? (too blurry) What is the best file type to use in mobile apps? I am developing an iphone app and I am using images with the same frame
What is the best file type to use in mobile apps?
I am developing an iphone app and I am using images with the same frame as the views with 72 dpis in a format file .png but when the detail is more complex (rounded corners or little dots in a circle) the images get very blurry.
Can anyone advise me?

Also, if you are going to use .png files it would be good to compress the files for performance. I have not had any image quality issues yet and I use tinypng
DPI is irrelevant. Ignore that. All that matters is pixel dimensions. Make sure you are making them at the dimension they will be used. Ie, if it's going to be 30px x 30px on the iPhone, make your image 30px x 30px. For retina, you'll want to make a second version at 60px x 60px.
PNG files are fine. But use whatever makes sense for your particular needs.
As for being 'very blurry' we'd likely need to see an example of what you mean to be of much more help.
