Types of Images: Complete Guide to Raster, Vector, File Formats & Uses (2026)
Types of Images
Digital images are everywhere — on websites and social media, in smartphones, engineering drawings, medical scans and satellite maps. But that doesn’t mean all images are created equal. Understanding the types of images helps you choose the right format for quality, performance, editing, printing, and sharing.
Some image types are better for realistic photographs, others for logos, illustrations, technical drawings, or animations. Each image type has its own pros, cons and best use cases.
In this complete guide, you’ll learn about the different types of images, how they work, common image file formats, their advantages and disadvantages, and when to use each one.
Quick Answer: What Are the Different Types of Images?
Images can be divided into several major categories based on how they are created and stored. The two primary types are raster images, which are made of pixels, and vector images, which are created using mathematical paths.
Other important image types include RAW images, HDR images, animated images, 3D images, medical images, and satellite images. Each type is optimized for different applications such as photography, web design, printing, engineering, healthcare, and mapping.

What Are Types of Images?
Types of images are the different ways of making, storing, displaying and utilising digital images. The types of images can be classified by their underlying technology, file format, purpose or method of creation.And if that’s a good thing, it’s a good thing.
For example, a photo taken with a smartphone is usually a raster image, stored as a JPEG or HEIC file, while a company logo is usually a vector image, stored as an SVG or AI file. Medical scanners produce image formats such as DICOM and satellites produce raster images for mapping and environmental monitoring.
Understanding image types helps you:
- Select the right format for your project.
- Maintain image quality during editing.
- Reduce file size for faster websites.
- Choose the best format for printing.
- Optimize graphics for search engines.
- Improve website performance and user experience.
How Are Images Classified?
Digital images can be classified in several ways depending on their structure and intended use.
| Classification | Description |
|---|---|
| By Structure | Raster or Vector |
| By File Format | PNG, JPEG, SVG, TIFF, GIF, WebP, AVIF, HEIC |
| By Purpose | Photography, Web, Printing, CAD, GIS |
| By Compression | Lossy or Lossless |
| By Motion | Static or Animated |
| By Source | Camera, Scanner, AI, Medical Device, Satellite |
Why Understanding Image Types Matters
Choosing the correct image type affects everything from visual quality and editing flexibility to website speed and storage requirements.
- Photographers need high-quality image formats for editing.
- Web developers require optimized images for fast loading.
- Designers use scalable graphics for logos and branding.
- Engineers rely on precise vector graphics for technical drawings.
- Healthcare professionals analyze specialized medical images.
- GIS experts work with satellite imagery for mapping and analysis.
Although hundreds of image file formats exist, most digital images belong to one of two major categories: raster images or vector images. Popular formats like PNG, JPEG, WebP, AVIF, BMP, and TIFF are raster formats, while SVG, AI, and EPS are vector formats.
1. Raster Images
Raster images are the most common type of digital image. They are made of thousands or millions of tiny squares called pixels. Every pixel stores color information, and together they create photographs, screenshots, and realistic graphics.
Common Raster Formats
- PNG
- JPEG (JPG)
- BMP
- TIFF
- GIF
- WebP
- AVIF
- HEIC
Best Uses
- Photography
- Website graphics
- Digital painting
- Social media images
- Scanned documents
- Medical imaging
2. Vector Images
Vector images are created using mathematical paths, curves, and shapes instead of pixels. Because they are resolution-independent, they can be enlarged to any size without losing quality.
Common Vector Formats
- SVG
- AI
- EPS
- PDF (Vector)
- DXF
- CDR
Best Uses
- Company logos
- Icons
- Infographics
- CAD drawings
- Maps
- Brand identity
3. RAW Images
RAW images contain unprocessed data captured directly by a digital camera sensor. Unlike JPEG files, RAW images preserve maximum detail, making them ideal for professional editing.
| Popular RAW Formats | Camera Brand |
|---|---|
| CR2 / CR3 | Canon |
| NEF | Nikon |
| ARW | Sony |
| RAF | Fujifilm |
| DNG | Adobe Universal |
Best For: Professional photography, color correction, and image editing.
4. HDR Images
HDR (High Dynamic Range) images combine multiple exposures to capture both bright highlights and dark shadows in a single image. This produces more realistic lighting and greater detail.
Common HDR Formats
- HDR
- EXR
- Radiance HDR
Applications
- Photography
- Gaming
- Visual effects
- Architecture
- Product rendering
5. Animated Images
Animated images display multiple frames in sequence to create motion. They are widely used on websites, social media platforms, and messaging applications.
| Format | Supports Animation |
|---|---|
| GIF | Yes |
| APNG | Yes |
| Animated WebP | Yes |
| Animated AVIF | Yes |
6. 3D Images
3D images represent three-dimensional objects and environments. Unlike traditional images, they contain depth information and can be rotated, rendered, or animated.
Popular Formats
- OBJ
- FBX
- STL
- GLTF
- BLEND
Used In
- Video games
- Product visualization
- Architecture
- Animation
- Virtual Reality
7. Medical Images
Medical imaging helps healthcare professionals diagnose and monitor diseases. These specialized images are generated using medical equipment rather than digital cameras.
Examples
- X-rays
- MRI scans
- CT scans
- Ultrasound images
- PET scans
Primary Format: DICOM
8. Satellite Images
Satellite images capture Earth’s surface from space. They are essential in mapping, agriculture, weather forecasting, environmental monitoring, and disaster management.
Applications
- GIS
- Remote sensing
- Agriculture
- Urban planning
- Climate monitoring
Common Format: GeoTIFF

Common Myths About Image Types
Myth 1: PNG Is Always Better Than JPEG
Fact: PNG is better for graphics with transparency, while JPEG is usually the better choice for photographs because of its smaller file size.
Myth 2: Vector Images Are Better Than Raster Images
Fact: Vector images are ideal for logos and illustrations, but photographs require raster formats.
Myth 3: Bigger Image Files Always Mean Better Quality
Fact: File size depends on image dimensions, compression method, color depth, and metadata—not only image quality.
Myth 4: WebP Replaces Every Other Image Format
Fact: WebP is excellent for websites, but formats like PNG, SVG, TIFF, and RAW are still better for specific use cases.
Myth 5: All Image Formats Support Transparency
Fact: Only certain formats, such as PNG, SVG, WebP, and AVIF, support transparent backgrounds.
Expert Tips
- Choose the image format based on the project rather than popularity.
- Use SVG whenever a logo or icon needs to scale perfectly.
- Compress images before uploading them to improve page speed.
- Use AVIF or WebP for modern websites whenever browser support meets your audience’s needs.
- Keep original RAW files for future editing.
- Save print-ready artwork in TIFF or other high-quality formats.
- Avoid enlarging low-resolution raster images because they can become pixelated.
- Use descriptive filenames and alt text to improve image SEO.
