Call me cliché, but Mondays stink. So I'm offering a couple useful sites to brighten your week. Zamzar: Free Online File Conversion

Zamzar.com is one of my favorite online discoveries in quite some time. The tool allows you to upload a file and convert it to another format of the same type. For instance, you can upload and convert a WAV audio file to MP3, a DOC file to PDF, a WMV file to MP4, etc. You can also upload a file and compress it to a ZIP file.

Once you've uploaded your file(s), you just select your desired conversion format and click "Convert." Within an hour (usually no more than a few minutes, depending on the number/size of your files), you'll receive an email with links to download your new files. The site even lets you convert multiple files at once.

Zamzar's free account lets you convert files up to 100 MB, but you can pay for premium plans.

Umbrella Today?

Sometimes the simplest things are the most useful. Such is the case with UmbrellaToday.com, a weather site that makes things easy.

It's always frustrating to visit a weather site, enter a zip code and get vague information and percentages. I didn't major in meteorology, and I don't want to read radar maps. Sometimes I just want to know if I'm going to get wet.

With UmbrellaToday.com, you simply enter your zip code to ask the question, "Do I need an umbrella today?" and the site gives you a big fat "YES" or "NO." You can also enter your mobile number and select a time to receive a daily text alert from the site.

Never again will my perfect quaff be ruined by Mother Nature.
