Screenshots can be captured with the help 0of the old print screen key, or with the help of any professional screen capturing tool. The main important thing to be remembered is the image should need to be sharp and the file size should be a reasonable limit.
There are three most commonly used image formats for sharing the captured screen images on the web, and they are PNG, JPEG, and GIF. If you use the windows snipping tool which is the default program for capturing screenshots in windows, you can simply select the format of the image that you save from the drop down menu.
Now, here are a few tips for choosing the formats
- If you capture a web page that is full of text and web page results, then choose GIF or PNG as JPEG adds noise to the image.
- Choose the JPEG format if you want to save the image with a really low size.
- Use PNG format if you wish to capture the program window or the window on your PC.
- Go for JPEG image format if you want to capture a frame from your video game, YouTube video, or a movie from DVD.
In simple words use PNG for saving images with web pages full of text, JPEG for photographs and places with small file size and GIFs for capturing solid images with colours and animation.
