jpeg, gif, png? Which ones are the best for keeping quality, but not using as much space. Is PNG accepted in all browsers?

Thanks

I got problems with PNG it doesnt work for me. If i want good quality then I use JPG for the headers pictures etc.

For the smaller pics, layout parts I use gif.

Its all personal.

Quality depends on the situation. Graphics that represent photograph quality are better using jpg for file size and png-24 for perfection (although the size can be large)

For images with defined lines, like text, using a gif or png-8 is usually ideal. Anything less than 256 colors as jpg will have noticeable lossy compression.

In some situations I seperate the background and text if I can't find a good middle ground. In this case I'd maybe have a jpg background, set as a background image in css, then have a transparent gif on top that is text. This is just an example.

As far as png support goes, all browsers support it. But IE does not support "alpha transparency" of png. So you cannot use transparent png's until this gets resolved. There are javascript hacks out there that can take care of this, but I've yet to bother with them.

I have found issues with png's and IE in colors not matching correctly. But other than that I pretty much use png's and jgp's. I find png-8 is always smaller in file size than a gif.

jpg for pictures
gif for images I make
ico for icons

It base on needs, like me i use .gif for buttons and for small stuff and for header or product pictures I use .jpg

png was developed by aol, no surprises when issues arise.

Problems have nothing to do with png, its IE that has trouble supporting it. Its a superior format to gif and jpg for lossless compression, although jpg does make smaller file sizes due to lossy compression.

I was not aware of AOL having anything to do with PNG and cannot find anything to support that? Links?

stick with jpeg or gif, gif if its more computer generated graphics that dont require as many colours, use jpeg when you need to have images with loads of colours or decent quality photos!

I usually use GIF for smaller images, and JPG if I want the images to be a good quality. PNG never worked out good for me, plus they are a big a file size, takes longer to load.

png-24 is a lossless compression with better file size than a .tif -- png-8 is akin to a gif, but is less in filesize as well. I am not sure where everyone is having problems with png's because they make better images. Obviously a 24 bit png will be much larger than a compressed jpg. If you need transparent images, use a .gif as alpha transparency (which is much better than .gif transparency) is not supported by IE.

Remember there are 2 kinds of png's. One is millions of colors - the other is 256 colors.

You can find a workaround for IE and png's here:

We've implemented this in the past, albeit with a bit of modification to the code.

I use .jpg,.jpeg for the majoirty of my images

in addition png is the best format to use when creating flash, hence i only use png when im creating flash animation! Other than that its gif and jpg all the way!!!
