Stuck choosing between vectorizing and upscaling your AI art? You're not alone. 'To vectorize or not to vectorize?' That is the question. Today, we will clear up the confusion. We will explain when to use a vectorizer or an upscaler and look at the pros and cons of each.
Understanding the Basics
Before we explain the pros and cons, let's cover the basics of vectorization and upscaling process. Both techniques aim to increase the quality of low-resolution images commonly produced by AI generators.
If you're planning to print your artwork on a t-shirt or display it on a large canvas, quality enhancement is crucial.
Either tool works in most cases, and using both is usually unnecessary. There are specific situations where one is more suitable than the other. The choice depends on your design process, editing needs, and how familiar you are with each tool.
Vectorization: Unveiling the Power of Vectors
What Are Vectors?
Unlike raster images composed of pixels, vectors use paths and points to create designs. This key difference gives vectors unlimited scalability without losing quality.
Pros of Vectorization
- Infinite Scalability: Vectors scale perfectly, so you can resize your artwork without losing quality, which is crucial for large-format printing.
- Editing Capabilities: Vectors give you powerful editing options for precise changes and color adjustments.
- Versatile File Formats: From SVG to EPS, vector files can be converted to many formats, making them easy to use across platforms and products.
- Smaller File Sizes: Even though they scale infinitely, vector files are usually smaller than upscaled raster images, which makes storage and handling easier.
Suitable Applications for Vectorization
Not all images are the same, so knowing when to use vectorization is important. Vectors work best for flat illustrations and 2D designs, ideal for digital artwork and simple graphics.
Cons of Vectorization
- Detail Loss: Highly detailed or photographic images may lose detail and look flat or simplified.
- Gradient Distortion: Vectors often struggle with gradients, breaking them into visible bands instead of keeping smooth transitions.
- Limitations on Seamless Patterns: Creating seamless patterns with vectors can cause small misalignments at the edges, breaking the seamless effect. Avoid vectors for pattern designs.
- File Conversion: Many print-on-demand platforms do not accept vector files, so you may need conversion back to PNG, which adds an extra step.
Upscaling: Enhancing Raster Images
Unveiling the Upscaling Process
Upscaling turns low-resolution raster images into higher-resolution versions, improving sharpness and detail for better visual quality.
Pros of Upscaling
- Preservation of Original Aesthetic: Unlike vectorization, upscaling keeps the original style and details of the artwork.
- Pattern and Gradient Integrity: Upscaled raster images keep seamless patterns and smooth gradients, preserving consistency and detail.
- Suitability for Detailed Artwork: Upscaling is ideal for intricate designs and photos, making it a strong choice for detailed artwork.
TIP: Upscale your image by a factor of 4 for digital use or printing. If you need further editing, upscale the image first, then use vectorization.

Cons of Upscaling
- "Ghosting" Effect: Upscaled images may show ghosting around edges, creating a foggy or blurry look, especially in some areas.
- Increased Graininess: Upscaling can add grain to images, especially in areas with strong contrast or fine details.
- Limited Editing Capabilities: Upscaled images are less flexible than vectors, limiting editing options and keeping you dependent on raster-based editing tools.
- Larger File Sizes: Files created by upscaling can be very large. These large files can slow down design tools and may not be accepted by some marketplaces due to file size limits.
Vectorization vs. Upscaling
In summary, both vectorization and upscaling effectively improve the quality of low-resolution AI art. Each method has its pros and cons, so do not worry too much about choosing one. Try both and see which works better for your workflow and style.
If you often work with vectors and like a clean digital look, a vectorizer may be the better choice. If you usually work with photos and use tools like Photoshop, an upscaler may be more suitable.
In the end, the choice depends on your needs and the type of artwork you create. Use the tool that best improves the quality of your AI art.
FAQs (Frequently Asked Questions)
Can I Combine Vectorization and Upscaling for Optimal Results?
While it is possible, combining both methods often brings little extra benefit and can make your workflow more complex. Choose the method that best fits your specific needs.
How Do I Reduce Graininess in Upscaled Images?
To reduce graininess in upscaled images, try different upscaling algorithms and settings. Post-processing techniques such as noise reduction can also help improve the final result.
Can I Print Vectorized Artwork on Different Merchandise Products?
Yes, you can use vectorized artwork on many merchandise products by exporting it to formats such as SVG, EPS, PDF, or PNG to ensure flexible printing options.
What Resolution Should I Use When Upscaling AI-generated Images?
The ideal resolution for upscaling AI-generated images depends on how you will use and print them. Aim for a resolution that keeps the image sharp while matching the desired output size. For printing on t-shirts or other merchandise, higher resolutions, ideally around 5,000 to 6,000 pixels, work well.
