I did not downvote, but you should make it ultra clear that you are looking for a webapp, not a desktop screenshot tool. I recommend you add a sentence describing how such a webapp could work, what input, what ouput. Also describe if you want a real screenshots (of a real browser really loading the page) or a mockup (embedding your image within the image of a browser). – nic Apr 5 '13 at 7:21

First of all, use a computer app instead of a web app to take screenshot. Here are some good screenshot application for Mac

Next you need to set your screen resolution to the highest possible resolution and it must take the screenshot in a pretty good resolution. Also check if there's some settings for the screenshot application regarding to the resolution of images.

Take the screenshot without any app

On Mac you can take screenshots without any additional app. See this to know how http://osxdaily.com/2010/05/13/print-screen-mac/

Then you can use the image on the clipboard to edit in an image editing software. Read this for a trick to get high resolution screenshots in photoshop http://www.turbophoto.com/Photoshop-Tricks/screenshot-photoshop-trick/index.htm
