Bitmap vs. Vector — What's the Difference?
By Tayyaba Rehman & Fiza Rafique — Updated on April 26, 2024
Bitmap images are pixel-based, ideal for detailed and complex pictures like photographs, offering high detail at fixed resolutions. Vector graphics use mathematical formulas to create scalable images, perfect for designs that require resizing like logos.

Key Differences
Bitmap images, also known as raster graphics, are composed of pixels in a grid. Each pixel has a specific color, and when combined, they create the full image. Bitmaps are ideal for photographs and detailed images but suffer from loss of quality when scaled up or down. On the other hand, vector graphics are not made up of pixels but use mathematical formulas to define paths and shapes. This allows vectors to be scaled to any size without loss of image quality, making them ideal for logos, fonts, and any graphics that need to be resized frequently.
Bitmaps are typically file-intensive, especially at higher resolutions because they store color information for each pixel. This results in large file sizes, particularly for high-resolution images. In contrast, vectors are generally more lightweight because they store only the formulas for reproducing shapes, not individual pixel data.
In terms of editing, bitmap images offer detailed editing at the pixel level, which is essential for photo editing. Vectors are less suitable for detailed image editing but excel in situations where broad modifications over whole areas are needed, such as adjusting the size and shape of graphical elements.
When it comes to application, bitmap images are preferred for digital photography and detailed artwork due to their ability to capture complex gradients and color variations. Vectors are favored in graphic design, architectural design, and CAD because they can be easily adjusted and resized for various formats and outputs.
Common file types for bitmap images include JPEG, PNG, and GIF, which are widely used across various devices and platforms. Vector graphics often use formats like SVG, EPS, or PDF, which are compatible with many graphic design software packages but require specific programs to edit.

Common Curiosities
What are the advantages of using vector graphics in web design?
Vector graphics load faster and scale better on different screen sizes, making them ideal for responsive web design.
How do file sizes compare between bitmap and vector images?
Bitmap files are generally larger than vector files because they contain detailed information for each pixel, whereas vectors store only the paths and points.
Why are bitmap images not ideal for logos?
Bitmap images can become pixelated when scaled up, making them unsuitable for logos that need to be displayed clearly at various sizes.
What is the main difference between bitmap and vector graphics?
Bitmaps are pixel-based and detailed but not scalable, whereas vectors are based on paths and can be scaled indefinitely without losing quality.
Can vector graphics be converted to bitmap images?
Yes, vector graphics can be rasterized (converted into bitmaps) for purposes like web usage, but this conversion is irreversible.
Can vectors handle color gradients as well as bitmaps?
Modern vector software has improved in handling gradients, but bitmaps still provide superior detail and subtlety in color transitions.
Are there any devices that cannot display vector graphics?
Most modern devices can display vector graphics, but they may need to be converted to a compatible format like SVG or rasterized into a bitmap for universal compatibility.
What software is needed to create vector graphics?
Software like Adobe Illustrator and CorelDRAW is specialized for creating and editing vector graphics.
Is one format better than the other for printing?
The choice depends on the project. Bitmaps are preferred for detailed images like photographs, while vectors are better for text and logos that must retain sharpness at all sizes.
How does zooming affect the quality of bitmap and vector images?
Zooming into a bitmap image reveals pixels and may cause blur, while zooming into a vector image maintains its crispness regardless of scale.
