When saving files or creating images, it is hard to figure out which image, file formats are best for your images. Some file formats will mess up the color or others will blur your pixels. That is why many times your images might come out odd looking or not what you want them to look like. Here is a general guide of the most commonly used formats for images.
GIF- GIF has been the standard format for almost all graphics and animations, but do not work well for other types of images. They will often come out pixelated or blurry. However, GIF is the only format that supports animation.
BMP- This is the long time only file that MS Paint supported. This has changed pretty recently starting with XP and Vista. Again like the GIF, BMP format often make pictures out of focus. Unlike the GIF, BMP does not really have a reason to be used anymore.
JPEG- JPEG or JPG as it is sometimes called is good for simple and non-sharp images. This would be ideal for those who do not need Hi-Def images. Out of the previous two, this one is still used commonly.
PNG- PNG is pretty new and not that commonly used as of yet. I almost always use this format in this blog, since it produces the sharpest images out of all of them.
Now if you are worried that your pictures turn out too blurry in JPEG(do not save a regular image as BMP or GIF), you can sharpen it to a certain point. But some of that sharpness will be lost once saved. PNG will almost always keep the image the clearest out of all of them.
If you are wondering how to make your photos in focus, you will need a photo editor that can sharpen images. MS Paint will not sharpen any image; you will need a more professional grade one. GIMP is what I use for most of my image editing and it is free. MAC, WIN and even Linux support it. While it is hard to learn how to work it, it is the best one that I have found. Sort of like a free Photoshop, which is great. You can also find some really great tutorials out there for it.
Here are some examples of the photo file formats and how one image can look very different depending on the file format.
You can see that BMP, GIF and JPEG all have color loss and blurry images, while the PNG has almost zero blue or color loss. You may need to click on them in order to see the images better.
