If you’re a web designer that’s into experimenting and trying out new applications (they don’t cost a dime), check out these 10 Adobe AIR applications perfect for web designers. Graphics designers, interaction designers, and web developers might also find this collection useful.

1) The Em Calculator created by James Whittaker is based on an article on 24 ways entitled Compose to a Vertical Rhythm. It’s a pain-free way of creating CSS code for typography set on a baseline style, allowing the design to maintain its typographic proportions (i.e. size, line height, margin, padding) when the web page is viewed at a different font sizes.

2) The AIR Icon Generator is for designers needing a quick icon/web 2.0 badge created. Using the tool is a easy as pie: enter the text you want to display, choose the icon you want to generate (there’s currently only two styles available) and the color, press “generate icon” and you’re good to go. The output provides four different sizes of the generated icon.

3) The Google Analytics Reporting Suite brings Google’s powerful website analytics tool to the desktop and adds several nifty features such as the ability to save/switch between different profiles (excellent for managing multiple sites/accounts for clients) and tab-based navigation for statistics pages you’ve opened.

4) We’ve all had to resize a batch of images at some point – thumbnails for image galleries comes to mind. If you’re looking for a quick-and-easy, free application – check out Shrink O’Matic. Set your desired options/parameters (Output size, Output name, Output format) and then drag your images into the interface (or use the file browser), and you’re done!

5) There are plenty of situations where you need to take a screen shot of a live site; maybe you’re documenting or collecting websites for your portfolio. WebSnapshot is a hassle-free tool to accomplish just that. You have the option to capture thumbnails, full page (entire width and length of the page), and/or the browser contents of live websites. As an alternative, try out WebKut, which has similar functions.

6) pixus is a pixel-based ruler for objects on your screen/monitor. It has skins for Internet Explorer 6 and Safari so that you can visualize how a design or object looks in a web browser. pixus allows you to save preset dimensions for later use.

7) Klok is a nifty, robust project time-tracking tool. Klok comes with pre-defined templates including Web Project geared specifically for web designers and developers.
