Raster vs Vector Graphics
When to use each format, what they can and can't do, and how to choose for POD.
Raster graphics (PNG, JPG, TIFF) are made of pixels — fixed grid of colored dots. Vector graphics (SVG, AI, EPS) are made of mathematical paths — infinitely scalable. Choose the wrong one and you get blurry prints (raster too small) or wasted effort (vector for photos). This guide explains when to use each, the conversion limits, and which platforms accept which formats.
Most POD sellers use raster (because that's what cameras and Photoshop output). Vector becomes essential for logos, scalable graphics, and certain print-on-demand products.
The Comparison
| Aspect | Raster (PNG/JPG) | Vector (SVG/AI) |
|---|---|---|
| Made of | Pixels (fixed grid) | Mathematical paths |
| Scalability | Limited (blurry when scaled up) | Infinite (sharp at any size) |
| Best For | Photos, complex artwork, gradients | Logos, icons, simple shapes, text |
| File Size | Larger (especially at high resolution) | Smaller (for simple graphics) |
| File Formats | PNG, JPG, TIFF, WebP, GIF | SVG, AI, EPS, PDF (vector) |
| Etsy Support | Yes (PNG/JPG only) | No (must convert to PNG/JPG) |
| Print Use | All POD platforms | Some platforms (Cricut, Silhouette) prefer |
| Tools | Photoshop, GIMP, Canva | Illustrator, Inkscape, Affinity Designer |
Quick rule: Photos and detailed artwork = raster. Logos, icons, and simple shapes = vector. When in doubt, vector for design files (it can always export to raster).

Why this matters
Choosing the wrong format wastes time and money. Designing a logo as a raster PNG means you'll need to recreate it as vector when a customer wants a 24×36 sign. Designing a photographic wall art as vector means working with non-existent vector tools. The cost of getting it right upfront is zero; the cost of fixing it later is hours of recreation. POD sellers should default to vector for graphics that will scale (logos, simple illustrations, text designs) and raster for photos and detailed artwork. Most products work fine as raster — only certain niches (cutting machines, signage, large-format print) require vector.
When to use each
Use Raster (PNG/JPG) when:
- Selling photographs or photo-based art
- Final output for Etsy/Amazon (they require PNG/JPG)
- Designs with complex gradients, textures, or photo elements
- Products at fixed print sizes (8×10, 11×14)
Use Vector (SVG/AI) when:
- Designing logos, brand marks, or scalable icons
- Selling files for cutting machines (Cricut SVG, Silhouette)
- Large-format products (banners, signs, billboards)
- Products that need to scale (small sticker AND large poster)
- Simple illustrations with flat colors and clean lines
Common mistakes
1. Designing logos in Photoshop (raster) instead of Illustrator (vector)
Logos need to scale from business cards to billboards. Vector handles this; raster blurs at large sizes. Always design logos in vector first.
2. Trying to "convert" raster to vector
Auto-tracers (Illustrator's Image Trace) produce poor results for complex images. Recreate from scratch as vector — it's faster than fixing a bad trace.
3. Selling vector files to buyers without explaining
Most Etsy buyers don't have Illustrator and can't open .AI files. Include both vector AND raster (PNG/JPG) in your bundle.
4. Uploading SVG to Etsy listing thumbnails
Etsy doesn't support SVG. Always convert to PNG (1000×1000+) for the listing image. SVG can be in the bundle for buyers who can use it.
5. Using vector for photographs
Vector can't represent continuous-tone photos efficiently. File sizes balloon, quality drops. Photos = raster, always.
