If you upload images online – and who doesn’t these days? – it is likely that you will be asked to convert them to JPG/JPEG first. If you are not sure why and how you have to do it, read on. This small article helps you understand it.
We’ll start with a brief introduction of these formats: each of them is created for specific uses and has its own advantages and disadvantages. BMP stands for Bitmap, while JPG or JPEG – for Joint Photographic Experts Group, who created the format.
BMP images are not compressed, and they have a higher resolution as compared to JPEG images. Each pixel in a BMP image has its own specific color, and graphics in this format are said to be most suitable for images with limited number of colors.
JPG files support up to 16 million colors, employ lossy compression, i.e. the format is capable of analyzing what information is important for a particular image and retains it during the compression, while the information considered as being secondary is removed. Each time you save a file, some data is lost and it is not recoverable. The amount of data loss can be adjusted according to the image size, high quality corresponds to low compression and the other way round.
While the human eye usually does not see the difference between the compressed and uncompressed images, their size can be dramatically different - the former images are much smaller than the latter. That is why JPEG is the format preferred on the Internet, and if you have a camera you would notice that images stored there are usually in JPEG format. A note: if you are trying to free up some space on your hard disk, converting your BMP images to JPG for storage could be a good idea too, unless you are really particular about retaining the quality and resolution of your pictures.
Now, what would be the best way to convert JPG to BMP Mac owners could make use of? All you need is a decent piece of software – a good Mac image converter to do the job for you. Actually a Mac batch image converter would be a better option, considering that we usually have a lot of images to work on.
