.gif files

at work im attempting to modify I programme that we use by replacing the Oracle logo with one of my works. The old file that im replacing is a .gif but each time I save our logo as a gif the quality is really poor. ive tried saving as all different other files that keep the quality but as soon as I upload it, the quality returns to what a .gif file looks like. As you can see the right hand side keeps its quality, this is a .png file and the original item that was on the right was a .png so it all makes sense. The old logo that was on the left had very good quality but mine doesnt (even though that was a .gif file)

i assume that the left hand side has to be a gif file and because it is limited to 256colours the main colour in our logo might not be within the 256.

is there a way round it? or the ability to up the quality of a .gif?or am i destined to change the colour to something within the 256? - tried with one of the basic colours and you still get a crappy quality!

when you save a gif, whatever program you use should ask you what compression techniques you want to use. I get the attached in paint.net. do you get a similar box?

gif only supports 8 bit colour pallette which is your 256 colours. If you have 1 colour with many shades that can easily chew up 256 colours.

Use a decent gfx app to reduce the colours in your image to 256, if you have option to play with the pallette you may be able to tweak the image.

Anti-aliased nice coloured text on a background will chew up loads of colours…

So in short reduce your colour depth to 256 colours/8-bit first using a decent image processing app - e.g. paint shop pro. Then, when your happy with quality, save as a GIF.
