I asked that question as part of my first BNI presentation a few weeks ago. Out of 28 members, only three knew the answer; two were members that I designed logos for, and the third was my mentor who helped me prepare for the presentation. I know that sampling is too small to accurately apply to a larger (internet sized) group, but I would be willing to bet that at least half of the people reading this don’t already know the answer either, and I would like to change that.
For those of you in a hurry, or who really try to avoid math whenever possible, I’ll put the tl;dr answer here first: Vector images can be scaled up (and down, and up again) indefinitely without losing detail – Raster images can’t.
If you would like to know more, aren’t intimidated by math, or aren’t sure what makes one image raster and another one vector, then please keep reading. I should say up front that most of the information I’ll be sharing is based on personal experience gained while working with both raster and vector images over the last decade, and observing their differences first-hand. Some of my math might be shaky at best, so I’m using it for illustrative purposes only. Also, this is going to be a horribly long post. For that I apologize.
What does ‘raster’ mean, oh wordy blog post writer?
After all of that, I’m almost afraid to ask: what about vector?
So, that was shorter than the raster explanation, right? Maybe? A bit.
Now that I’ve buried you with technical details, provided I don’t confuse you and you stuck with it rather than close the tab all annoyed at me for my babble-fingers, it should be obvious why you would want your business logo, the image that is used to represent your company to your customers, to be available in a vector format. That said, there are some logos out there that would be very difficult, if not outright impossible (for me at least), to convert into a vector image. For them, I can only hope they had the foresight to get a version of their logo at a very high-resolution, or else they could have problems down the road.
