People seem to use the word ‘logo’ and ‘vector’ interchangeably. However, vectors are actually a type of file format (most commonly; .ai or .eps) I use a program called Adobe Illustrator to create these vector logos. They have crisp edges, are high resolution, scalable to any size you need and can be saved out to almost any format that you, or a printer, would require.
Most clients don’t need the actual original ‘vector file’. Unless you have the right program to open and modify them, they will be of no use to you. So, depending on what you need the logo for, typically I will provide it as a high-res .jpeg or .png file. Technically, once the logo is saved to these file formats, they are no longer considered actual “vector files”. But they are still perfect for your everyday uses. (Such as; for using online, incorporating into a flyer or a Word document…etc.)
I will always keep your original vector file in case you need your logo in a different format for future projects. And, of course, I if you request the original vector file, I will provide that as well.
