When we started this site, we were looking for a great tool to convert youtube usernames into their channel IDs since you want to use channel ID for certain things. We use it mostly for API connections to make our page more dynamic and also to be able to get the latest information about the influencers. We decided to create a simple tool that helps you convert a youtube username into the channel ID. Some channels use the channel ID as a slug already. One of our pages is doing that since we have not added a username to it yet.
This is a channel that uses channel ID instead of username: https://www.youtube.com/channel/UCgB58IUuE78N9c4PrATPEWw

This tool is used if you find a youtube channel with the URL like this: https://www.youtube.com/user/PewDiePie – then you take “PewDiePie” and enter it below and it will result in getting he’s channel ID (UC-lHJZR3Gqxm24_Vd_AJ5Yw).
