Images play an important role in eLearning courses. As an eLearning developer, you should know about the different types of image formats used in eLearning courses. Each format has its own merits and demerits. In this blog, I would like to share the some of the image file types and their benefits and limitations.
PNG stands for “Portable Network Graphics”. This is the universal format recognized by the World Wide Web consortium. This image type supports all modern browsers.
We can use this format for images that don’t have a background. It has a great feature: lossless compression – that is when you are save the original image to PNG format , the image data is not lost. But the file size is more compared a to other formats.
JPEG stands for “Joint Photographic Experts Group”. This is the most popular image format that used in eLearning courses. When you save the original image into a JPEG format, some information is lost, also the image size will be reduced. This format doesn’t support transparency.
GIF is short term used for “Graphics Interchange Format”. It has a great advantage –we can create animation effects. This has the smallest file size compared to the other formats. In this format, the images are of poor quality. It is more suitable for diagrams, cartoons and logos. But it supports only 256 colors.
The BMP image format is within in the Microsoft windows operating system. The file size is large and uncompressed. But the images are og high quality, rich in colors and compatible with all Windows OS. BMP files are also called paint images.
TIFF is short term used for “tagged image file format”. It doesn’t use compression when saving the image. The quality of the image will be good.
There are many other image formats out there that can you use in eLearning courses, But these are the ones that we normally used. I hope you found this blog informative. Do share your views.
