So I am fairly new to Krita but I am really enjoying the format and capabilities of the program. I love to create pixel art specifically, one problem i have is I cannot export the work without it becoming extremely blurry and small. Is there any way to export the work in a larger size but maintain the art?

* What is the size of your image in pixels?
* What are the dpi settings of your image?
* What file format are you using?

I am generally using 100 x 100, with a 1000 dpi and into png format.

1000 dpi! That means 1000 pixels per inch -- and that means your image's size will be one tenth of an inch by one tenth of an inch.

Ahhh thank you for the clarification.

How do I use this to create a better export for an image?

Try setting the dpi to 72 and ensure it is saved as png or gif. There might be some high dpi trickery going on that the other program you're viewing the image with is using, and their scaling algorithm is intended for photos, not pixelart.
