If you’re not into something like Adobe Photoshop or Illustrator, you might not know what these two terms mean. They are important to know when making a logo or any other type of computer-created design because they are for two different styles of photos.
Raster – Programs like Adobe Photoshop and GIMP are raster programs because raster is when the image or graphic is made up of individual pixels or squares of color. Pictures are like this. This often means that pictures are higher quality and designs can have better color gradients. A drawback is that any changes to the size of the image or design immediately make it very messy looking.
Vector – Adobe Illustrator and Inkscape are vector programs because it uses mathematical equations to create the parts of the image or design. It goes off of X and Y axis. This makes edges very crisp and clean, as well as allowing for easier scaling. However, it is difficult to get a gradient that is not build in to the program.
Ultimately, vector is the best option for logos because you will need many different sizes of the logo and vector has clearer edges.
As for file types, there are a ton, but the important ones for logos are jpg, png, eps, and tiff.
Eps is an older vector file type that Adobe Illustrator can export to, but is not preferred. What is better is using a pdf or converting to a jpg, png, or tiff. This can be an option for a master logo file that you can resize without consequence.
Jpg is the most efficient file type as it is often the smallest size when it comes to data use. Even a large image can be fewer KB than the same image of a different type.This is a huge but often overlooked detail when it comes to website images, and is the best choice of file type for rectangular graphics or images. Large images on a website take longer to load, so any potential client might have to wait longer to see your page. Many people are impatient when it comes to internet speed, so say goodbye to that client if your page is too slow. Jpg images can help shorten the loading speed, making your website a more pleasant experience. A couple downsides are the possibility that too much editing or uploading can compress a jpeg file too much and it gets pixelated, and jpg cannot have transparent backgrounds like pngs can.
Speaking of png, they are very high-quality in addition to allowing transparency. Transparency can be important for logos and can add some oomf to your website’s appearance, so using pngs would be vital as long as it’s a smaller file size.
The last file type, tiff, is very similar to a jpg. The main difference is that tiff files don’t compress on editing or uploading. A lesser version of the jpg, essentially, since tiff are often large file sizes and don’t have transparency like png. Tiff files are seldom used on the internet.
You are getting so smart.
