I have been curious what format you are using for your logo - jpeg, gif, png, svg?
and why you chose it?
and why you chose it?
I have some transparent images that are png and gif. Are png better quality than gif? I get many from free stock websites or creative common but you usually can not pick format. I did not know if one is better quality than other.I tend to use the png format, mainly because as previously stated the quality of the images and mainly because I want to be able to use the transparent backgrounds. This way the images blend into the site colors much better.
Thanks for the information. So then it would be better to have a png image if I have any choice over gif?There are many differences between the GIF and the PNG format. The reason that I use PNG is the lossless quality and the compression of a png file is 5 to 25% better than that of a GIF file.
Let's look at some specs on the two formats.
GIF (Graphics Interchange Format)
The GIF format is a format that uses a LZW algorithm for compression. This compression algorithm traces and keeps track of the colors to help in the reduction of the file size. The strongest point with using the GIF format is that the support for GIF across the major browsers is well documented and GIF has been the default choice for simple graphics across the web for many years. Although that is beginning to change.
PNG (Portable Network Graphics)
PNG is a extensible file format for the lossless, portable, well compressed storage of raster images. PNG has provided us a patent-free replacement for GIF and many of the TIFF images in use today. There was a patent held on the GIF LZW algorithm that limited how GIF images could be deployed when GIF was in the heights of its popularity, that patent has since expired. Indexed-color, grayscale, and truecolor images are supported, plus an optional alpha channel. Sample depths range from 1 to 16 bits.
For the Web, the PNG file format has three main advantages over GIF:
PNG also compresses better than GIF in almost every case (5% to 25% in typical cases).
- alpha channels (variable transparency),
- cross-platform gamma correction (control of image brightness) and color correction
- two-dimensional interlacing (a method of progressive display).
So I hope that explains why, in my opinion png is a much better format for use on the web. Many of the points I have laid out here come directly from the W3C standards on web development.

Hi Mike. Since you are on the subject, I have a question for you. I have done a little looking in the past but couldn't find a clear answer.Ahhh..... but that was not a part of the question, the question was on png and gif.
If transparency is needed, which many times it is, then you stick with the png format. But if size is more of a concern then you go with jpg. JPG is one of the highest quality, based on the compression scheme, and smallest file size.
Thanks, I did not know there was really any difference with them. So if I have some good images that I am or will use for my blog should I convert the gif images to png images?If given a choice I would always choose png formats.
No, they are not the same and in fact have very few technical aspects in common. The main reason for the development of the png format was that the GIF format used a patented LZW algorithm for compression. This made many developers nervous as there was no guarantee that the compression algorithm would remain license free.
So then a png is better to be more accurate for colors if you want them to retain their accuracy? I saw something regarding color quality, last year I think, but I can't remember exactly what the details were or where I saw it. I do tend to see a lot more of the newer images used around the web being in the png format.I normally stick with png because the images I use are usually complex and when dealing with business sites and also the colors for logos and trademarks has to be exact.
A couple of years ago when I started thinking about making my website more mobile friendly I had read something about png's being better for mobile device viewing than jpg, which was one that I was using a majority of. That's one reason why I started using png's whenever I can. I don't remember all the details but I saw similar information from a few different resources. I don't know how accurate that is but frm the details I saw, it seemed like it would be accurate.I had not heard that comment about mobile devices but I will do some research and testing. Looking at the comment in a neutral light and understanding the technical specifications on each format it kind of makes sense as png files tend to scale down and up better than jpg.
