The Difference Between Vector and Bitmap Images

This gets somewhat technical, but it's important to know the difference between vector images and bitmap images and to know where to use which one for the best results.

Have a look at the image to the right. The first column shows what happens to a vector image when stretched to a different size. No matter how big you stretch a vector file the outlines stay crisp.

By contrast the next column shows how terrible a bitmap looks when you stretch it. Bitmap images are made up of pixels, so stretching it forces the computer to stretch the pixels, which is why you see the pixels (blocks) clearly in the bottom one.

Chances are that you've seen pixelated (blocky) images printed in newspapers. Those are the folks who didn't come to LogoAnts to get their logos :-)

Seriously though, those are the folks who only have their logo in bitmap format. Bitmap is not ideal for printing. If you print it small enough it will look ok, but bitmaps are not practical for banners, billboards, sign writing etc.

That said, the bitmap format is not the image format from hell! We need bitmaps because our web sites need them. All images that you see on the web are bitmaps.

Vector Formats:

  • CDR (CorelDraw format)
  • AI (Adobe Illustrator format)
  • EPS (Encapsulated PostScript)
  • EPSF (Encapsulated PostScript Format) (same as EPS)

Bitmap Formats:

  • JPG: Good for photos and images with many colors
  • GIF: Good for logos and images with limited colors. Supports transparency.
  • PNG: Good for logos and photos. Supports transparency.

To summarize:

INSIST on receiving your logo in vector format AND in bitmap format. If your logo designer cannot provide both these formats, don't order your logo from them! Being stuck with only a bitmap logo will almost always cause headaches and additional costs later on in the life of your business.

At LogoAnts:

At LogoAnts we supply your final logo files in both vector and bitmap formats. We usually design in CorelDraw and send you the original CDR file when the logo is complete, but we can also provide an AI, EPS or PDF version of your logo if needed. No extra charge for extra logo formats. As standard we also supply JPG, GIF and PNG versions of your logo, with additional formats like PSD and TIFF available on request - also free of charge.


Questions? Please get in touch. We look forward to hearing from you!
