Comments on: What is the difference between TIFF, GIF, JPG, JPEG, PNG, and a BMP file? http://tips4pc.com/articles/file%20formats/what_is_the_difference_between_t.htm Computer Tips and Tricks from Tips4pc Wed, 23 May 2012 04:39:45 +0000 hourly 1 http://wordpress.org/?v=3.3.2 By: branded items http://tips4pc.com/articles/file%20formats/what_is_the_difference_between_t.htm#comment-28073 branded items Mon, 16 Apr 2012 09:34:02 +0000 http://growingtomatoestips.com/?p=1774#comment-28073 And here comes the fun part. Has anybody thought about how to create a JPEG? It turns out that there are libraries and there are few of them: • Adobe uses its own libraries, there are several, for example, Adobe Photoshop, Save for web – used for saving in the WEB. • LibJPEG . Use almost all the programs that are able to save in JPEG, including Adobe Fireworks. The library has a very interesting LibJPEG program – JPEGTran (optimizes the image without losing quality.) It makes sense to use it if you create a JPEG image in Photoshop or Illustrator and optimize through JPEGTran, you get the maximum effect of optimization, because it appears that you have two libraries. Unfortunately, I have failed to get Photoshop to save a JPEG, without loss of quality. Remember when we resaved image in JPEG, it turned out that the new image is larger than the original. This is due to the libraries’ specifications. And here comes the fun part. Has anybody thought about how to create a JPEG? It turns out that there are libraries and there are few of them:

Really old browsers, such as IE 3, don’t support the PNG format, but most Web designers now choose this format over GIF because so few people use such old browser. Browsers as recent as IE6 don’t display transparent PNG files properly, which is unfortunate because PNG files tend to handle transparency better.

Thanks again for explaing the relative merits of these different formats - it has changed a crisis into a solution.

It was exactly what I was looking for - the right amount of information (not too little, not too much) and was easy to understand. From now on I'll come to your website instead of wasting my time combing through Microsoft's "Help" information trying to find what I need. Very often I end up really aggravated with Microsoft's "Help" because either I can't find anything addressing my question, or I find a little bit of information, but it's not thorough enough to answer my question.
