It depends on your file system. Some filesystems are CASE sensitive but typically JPG and jpg are the same thing.

When saving an image as a jpg 100, it will have higher quality and larger file size compared to saving it as jpg 20, which will result in lower quality and smaller file size.
.html is not an image file, so it can't be converted to .jpg unless the .html file has images in it, in which case you would show extensions and then click in the name box and change .html to .jpg
When comparing JPG 100 and JPG 20, the main difference lies in image quality and file size. JPG 100 has higher image quality with less compression, resulting in a larger file size. On the other hand, JPG 20 has lower image quality due to higher compression, leading to a smaller file size but potentially reduced image clarity.
The main difference between JPG and TIFF file formats is the way they store image data. JPG files use lossy compression, which reduces file size but can result in some loss of image quality. TIFF files, on the other hand, use lossless compression, which preserves image quality but results in larger file sizes.
Show extensions and then click in the name box and change .jpg to .html you will then be able to open your image file with your internet browser.
Most common graphic file extensions are: .jpg .jpeg .png .gif (for animated images)
Videos and moving pictures differ in coding methods. Moving pictures have file extensions like .jpg, while videos have file extensions such as .mp4.
"Jpeg" and ".jpg" are the same thing. The only difference is that most people prefer to say "jpeg" rather than "dot J.P.G."
