The long and short of GIF and JPEG
Misuse of 2 types of files
Do you often feel confused what to use for your images Web – GIF or JPEG? And more importantly why?
Great. You deserve praise as confusion leads to understanding. Here is what they've been looking all the way!
In essence, they are formats in which web images are created in any file with a. jpeg o. gif recognizing by a browser, as an image file.
A good website is one part loads quickly in a browser. Okay? Well, for this to happen, your website has to be small in file size. GIF and JPEG file formats compresses images so that it is web worthy.
This is vital for you Do not play when deciding what to use when. This is what you need to know (a subtle reminder and congrats for the high-tech guys who know)
GIF (Graphics Interchange Format)
- Pronounced as "jiff" . Thought you got to know it. - GIF was the first-ever image format created for use on the web. This implies that all browsers of all versions can read images in GIF format. - GIF transparency can icorporate. This is great. Is not this? Especially when you want your graphic to blend into the background. - GIF compresses an image using LZW compression. Confused? In short, this means that the image quality not degraded when compressed. The deterioration of the picture begins to emerge only when you have more than 256 colors. - Good results can be obtained using GIF when there is a large area of flat color in the image. And when you use fewer colors. The fewer colors the better. - Can be animated GIF. All animations, save flash movies more advanced, are GIF files.
JPEG (Joint Photographic Experts Group)
- Pronounced as "jay-peg" . Okay, as of now you know how both are pronounced. - JPEG uses a lossy compression scheme. This means that, in fact, lose some data during compression. The more compressed, more quality is lost. You, therefore, we must find an appropriate balance between file size and image quality. - JPEG compression ratio can be controlled. The higher the compression ratio, the smaller the size of the image. And as you've guessed, eh? The lower the quality. - JPEG is the best use of the images photographs. The subtle colors and gradients of an image, the better. - Browsers take longer to display JPEG images.
Narrower features JPEG and GIF
One of the worst mistakes (and will hopefully not) a web designer can do is choose the correct format for a particular type of image. As rule, for images with few flat colors, choose GIF. Images with many colors and gradients, you can go to JPEG.
Simple enough. Here it's your turn to see a couple of technology a little difficult to understand with regard to JPEG and Jiff € |
Belonging to JPEG, if the horizontal rows pixel subject to change frequently, without patrons, then a JPEG may allow a smaller file, even if it is to possess only few colors.
For designers, if they can save a few kilobytes on each image, you can dramatically improve the load time of pages loaded images intended for users with slow connections.
Furthermore, although you can have animated GIFs, this is rarely a good idea in terms of design.
There are some things you can do with GIFs that can not be done with JPG files. The best way to get smarter web images and graphics is up to you: the technology is available to be used only selectively for spectacular results. So let's take the understanding of high technology!
