If you are looking for cool development and productivity tools, here are a few, created by me, and available as handy Chrome Chrome extensions:
Builder.CSS is a free tool for merging and minifying style sheets into a single file, using some of the coolest HTML5 features like drag and drop of local files and processing them without uploading to the server. I am happy to announce that recently Builder.CSS has evolved to a free online service with tons of improvements, brand-new and amazing interface, drag and drop of local of styleshets from the desktop, predefined projects and much more.

Image2Base64 is an online tool, provided by Acid.JS Web.UI for conversion of image files to base64 data URIs. It implements the new HTML5 file API, and the selected images are processed entirely on the client without uploading them onto the server.

Hasher is an online service for creating message digests with a wide range of more than 40 encryption algorithms. Depending on the choice of the user, after the encryption hashes are stored in the browser’s local storage in convenient JSON format so they can be used or deleted later.
