: How do I enlarge a small raster logo without losing quality? A logo has been passed on to me that was made with small dimensions (500px x 300px). It is not a vector logo and they use

There are some resizing programs that have diferent algorithms than the tipical bicubic.

The main diference is that this kind of programs try to preserve the sharp edges between colours (the bicubic aproach is to soften the borders) so, in this case becouse the type of gaphic could work.

They don't perform miracles, but can help you to enlarge the image lets say 300%.

Here are 2 that I have used, but there are plenty more.

1) Before trying to enlarge them I would clean a bit the image, enhance a bit the colours and clean any jpg artifacts.

2) Test diferent algorithms untill I find something decent. Don't force the resizing too much. I would recomend 300% max.

3) Sharpen a bit the final result.

4) Think the posibility to vectorize this result.

5) Clean and optimize this vectorized version. This could work as a "new version" and the client should consider having this vectorized version as the "official" logo.

But at the end there is no way of resizing a bitmap in a magical way.

If you want to use it for a web-page or a ruff sketch it is ok, if you want to print it you should not use it.

Well, you can, but it would only be "good" at a certain width (1 to 3 cm i guess).

I would suggest NOT to redraw it in Illustrator as you always ALTER it, which is never a good idea.

In such cases you have to contact your client(?) to get a useable Version of the Logo, either vector based (BEST!) or in high resolution. Otherwise you would not be able to produce decent quality. (I speak of printing...)

From what you've stated, you're a little stuck for choices. As it's impossible to add pixel quality, improving the quality is tricky.

Personally, in your situation I would print the logo as best as possible, then photography it as best as possible. Some photoshop editing, better quality. If you have a good printer and good camera, you should be good to go.
