Key Takeaways
- Vectors excel for logos, icons, illustrations, and anything that needs to scale — rasters win for photographs and complex textures
- SVGs under 1,000 paths are almost always better as vectors; above 10,000 paths, consider rasterizing for performance
- Always export raster images at 2x resolution for retina/HiDPI screens (e.g., 2160x2160 for a 1080x1080 display)
- Hybrid approaches (SVG for icons and text, PNG for complex areas) give you the best of both worlds
- The ideal workflow is: vectorize first for maximum flexibility, then convert to raster only when a specific use case demands it
The Conversion Question
Vectors aren't always the answer. Sometimes raster formats serve better. This guide helps you make informed decisions about when to keep vectors and when to convert.
"The best designers don't pick favorites between vector and raster — they pick the right format for each job.
When Vectors Excel
Best for Vectors
Vector Strengths:
- Logos and branding
- Icons and UI elements
- Illustrations with solid colors
- Text and typography
- Diagrams and charts
- Responsive graphics
- Print at any size
- Animation targetsVector Advantages
Key benefits:
- Infinite scalability
- Small file sizes
- Easy color changes
- CSS styling
- Accessibility
- Animation support
When Raster Wins
Best for Raster
Raster Strengths:
- Photographs
- Complex textures
- Realistic shadows
- Gradient-heavy designs
- Photo effects
- Very complex illustrations
- Specific pixel outputRaster Advantages
When raster is better:
- Continuous tones
- Complex color transitions
- Photo manipulation
- Filter effects
- Reduced processing
- Universal compatibility
Pro Tip: A quick rule of thumb: if your design has more photographic detail than geometric shapes, go raster. If it has more solid colors and clean lines than photo-realistic detail, go vector. When in doubt, start with vector — you can always convert to raster later, but going the other direction loses quality.

Complexity Analysis
Complexity Threshold:
< 1,000 paths: Vector usually better
1,000-10,000 paths: Depends on use
> 10,000 paths: Consider rasterUse Case Matrix
| Use Case | Recommended |
|---|---|
| Logo on website | SVG |
| Hero background | Depends |
| Product photo | Raster |
| Icon set | SVG |
| Complex illustration | Case-by-case |
| Text/typography | SVG |
| Texture overlay | Raster |
Performance Considerations
Performance Impact:
Simple SVG (10KB): Fast render
Complex SVG (500KB): May lag
Same as PNG (100KB): ConsistentConversion Scenarios
Social Media
Platform requirements:
Typical Requirements:
- Fixed dimensions
- Raster formats only
- File size limits
- Specific aspect ratiosConvert: Vector to optimized PNG/JPG
Email limitations:
- Limited SVG support
- Inline images common
- File size constraints
Convert: To PNG with fallbacks
Print Production
Print considerations:
Print Decision:
Large format → Keep vector
Complex gradients → May rasterize
Photo elements → Raster
Text/logos → VectorLegacy Systems
Compatibility needs:
- Older browsers
- Legacy software
- Specific format requirements
Convert: To universally supported formats
How to Convert
Export Settings
Optimal raster export:
Web Use:
- PNG-24 (transparency)
- JPG (photos, no transparency)
- Resolution: 2x for retina
- Quality: 80-90% for JPG
Print Use:
- TIFF or high-res PNG
- 300 DPI minimum
- CMYK color spaceMaintaining Quality
Export Process:
1. Determine final size needed
2. Calculate resolution (2x for screens)
3. Export at target dimensions
4. Optimize file size
5. Test across devicesBatch Conversion

Tools:
- Illustrator Actions
- ImageMagick CLI
- Online batch converters
- Build process automationFree SVG Tools for Crafters

Progressive Enhancement

<source srcset="image.svg" type="image/svg+xml">
<img src="image.png" alt="...">
</picture>Layered Approach
Combine formats:
- SVG for icons/text
- PNG for complex areas
- Composite in final layout
Responsive Images
Different formats at breakpoints:
<picture>
<source media="(min-width: 800px)" srcset="large.svg">
<source media="(min-width: 400px)" srcset="medium.png">
<img src="small.png" alt="...">
</picture>Modern browsers support the <picture> element with SVG sources, letting you serve vectors to capable browsers and PNG fallbacks to older ones. This progressive enhancement approach gives you the best quality on modern devices without breaking compatibility.

When to Use Vectosolve
Vectosolve is ideal when:
- Source is raster, need vector
- Scalability required
- Editing needed
- Web use planned
After Vectorization
Consider converting back when:
- Final use requires raster
- Complexity too high
- Specific format mandated
Decision Checklist
Keep as Vector When
- Scalability needed
- CSS styling required
- Animation planned
- Accessibility important
- File size advantageous
- Editing anticipated
- Print at multiple sizes
Convert to Raster When
- Universal compatibility needed
- Complex gradients/effects
- Platform requires raster
- Performance issues with vector
- Specific dimensions fixed
- Photo/texture content
Conclusion
The vector vs. raster decision depends on use case, complexity, and requirements. Vectors excel for scalable, styleable graphics while rasters serve complex, fixed-dimension needs. Use Vectosolve when you need vector flexibility, then convert to raster only when necessary for specific applications.
| Scenario | Keep as Vector? | Convert to Raster? | Reason |
|---|---|---|---|
| Logo on website | Yes (SVG) | No | Scales to any screen; tiny file size |
| Photo-realistic illustration (10k+ paths) | No | Yes (PNG/WebP) | Rendering performance; browser lag above 10k paths |
| Print billboard (logo) | Yes (AI/EPS/PDF) | No | Must scale to any physical size without pixelation |
| Social media thumbnail | No | Yes (JPG/PNG) | Platforms rasterize on upload anyway |
| Icon set (under 500 paths each) | Yes (SVG) | No | CSS-styleable, animatable, resolution-independent |
