Dirpy was one of my favorite web-based converters that I relied on to convert rare Asian songs that were nowhere to be found on iTunes or Amazon. It had minimal ads but no popups at all; and offered options for ID3 tags, file re-naming, audio bitrate selection and even video downloading.
There are a number of desktop converters that can perform more or less the same function. Web-based converters seem to be scarce but here are some of the better ones that fill the void, although they understandably pack many ads to survive. So enable your popup-blocker and convert away!
Sites That Let You Choose Tags Or Audio Bitrate
ClipConverter may just be the best YouTube to MP3 converters in this list as it offers options to increase or decrease the volume, and choose between mono or stereo. The really neat part? You can also choose the bitrate, edit ID3 tags for artist, title and album information; and download the video on the same page without having to wait for a confirmation email of any sort. That’s always a plus since that you’ll save yourself from having to supply an email address and getting more future spam.
The thing is, it doesn’t only convert YouTube videos to MP3. In fact, it can convert to other popular video formats such as MP4, FLV, AVI, etc. while also letting you choose the video aspect ratio (4:3, 16:9, or even custom dimensions). It supports the more popular video-sharing sites, including YouTube, Google Video, Sevenload, MySpace, Dailymotion (HQ), Vimeo (HQ), Metacafe, MyVideo, and Veoh.
HDDownloader is the wise suggestion of a reader, and it’s the only one on the list that has a handy bookmarklet and a way for you to download the MP3 the easiest way possible: just append “sing” into the beginning of the YouTube URL, making it singyoutube.com/rest-of-the-url. Doing that will lead to you the HDDownloader site, where you can choose audio bitrates and be on your way to getting the MP3 file. You can also choose to download the video for which you’ll need to authorize a Java applet to run.
With a simple interface, FetchMP3 will take any YouTube video URL and offer you low, medium, high and ultra quality downloads if you sign up, which allows you to view your most recent downloads. Alternatively, if you don’t want to sign up, you can choose custom conversion and edit ID3 tags, as well as choose starting and ending times. FetchMP3 seems to only take YouTube and Dailymotion videos so far. It also has an official Firefox extension.
MediaConverter (first included in 18 Free Ways To Download Any Video Off The Internet) has always been a personal favorite web-based converter since it operates without asking me for email addresses, and it offers downloads to popular formats on the same page. The neat interface also rocks, as it sports some cool widget-like modules for information with unobtrusive ads, unlike most other online converters.
You can browse YouTube on the left module or simply enter the YouTube URL of the video, and select MP3 as the output format. You can also check the “I want to set advanced options” box to choose an audio codec and bitrate. While you can only do 5 conversions on any day (unless you sign up for a premium account), there are lots of supported sites, including the major ones that ClipConverter supports, as well as blip.tv, Break and Facebook. MediaConverter has an official Firefox extension that downloads and converts videos online.
Bonus Direct Video-To-MP3 Conversion Site
YouTube-MP3 doesn’t have too many ads or too many functionalities, but it allows you to download YouTube videos in MP3 format, as well as HTML and BB codes with links to the download page. The minimalistic site is available in several European languages.
There are general web-based converters, such as Zamzar and [NO LONGER WORKS] FLVto that could really do the job, but if you know that you want only the audio, these are probably the services to look at.
What converters, browser-based or otherwise, do you use to convert YouTube videos to other formats?
