LOGO FILE GUIDELINES
What is the difference between bitmap (JPG / PNG / GIF) files and vector files (EPS / SVG / AI)? And what size file is needed and resolution? The information below will explain the differences in these two types of files.
The guidelines for what we will need for your logo file to be used effectively on the website as well as the presentation screens at the banquet are as follows:
BITMAP
A bitmap file (or bitmap image) is a type of digital image made up of a grid of individual pixels, where each pixel holds a specific color value. The most common file extension for a bitmap file is .bmp, though the term “bitmap” can also describe other pixel-based image formats like .png, .jpg, or .gif.
File types:
.png or .jpg
Resolution:
300 dpi (dots per inch)
Dimensions:
Minimal 2000 pixels wide / high — whichever dimension is greater.
VECTOR
A vector file is a type of image file that uses mathematical formulas to represent shapes, lines, curves, and colors, rather than individual pixels. This makes vector images scalable without losing quality, meaning they look sharp at any size.
File types:
Common Vector File Formats
- .SVG (Scalable Vector Graphics) – widely used on the web
- .AI (Adobe Illustrator) – native to Adobe Illustrator
- .EPS (Encapsulated PostScript) – used for print and graphic design
Fonts:
Either all text is outlined or font files are included in upload.
Dimensions & Resolution:
Not applicable.
MORE ABOUT BITMAP FILES
Key Characteristics of Bitmap Files:
-
Pixel-Based: The image is composed of a matrix of tiny dots (pixels). Each pixel corresponds to a specific point in the image and contains color information.
-
Resolution-Dependent: Bitmap images have a fixed resolution. When you scale them up, they can become blurry or pixelated because you’re stretching the pixel data.
-
Large File Sizes: Uncompressed bitmap files (like BMP) can be quite large, especially at high resolutions and color depths.
-
Color Depth: Bitmap files can support various color depths, from monochrome (1-bit) to millions of colors (24-bit or 32-bit with transparency).
MORE ABOUT VECTOR FILES
Key Characteristics of Bitmap Files:
-
Resolution-Independent: You can scale a vector image up or down infinitely without it becoming blurry or pixelated.
-
Smaller File Sizes: Typically smaller than high-resolution bitmap files because they store equations, not pixel data.
-
Editable Elements: Each part of a vector graphic (like shapes or lines) can be individually edited without affecting the rest of the image.
-
Best for Graphics and Logos: Ideal for designs like logos, icons, fonts, and illustrations that need to be resized frequently.
