Convert all sorts of files online – from video to image, camera raw to JPG, PDF to PNG and more. Also, you can resize images to reduce file size.
The Select method is more efficient than the ConvertAll method. It works on all IEnumerable<T> objects, while ConvertAll only works on a list of objects.
What is a JPEG File?
JPEG is a popular image file format that allows users to save images with a smaller storage size. It uses the method of lossy compression to reduce file size without sacrificing picture quality. If you want to know more about what is a jpeg file read below.
It is a 24-bit still raster image format that can support up to 16 million colors. However, it does not support transparency.
JPEG is a lossy compression format, which means that some original image information is lost during the compression process. This can result in a noticeable degradation of image quality. Although the standard allows for an optional lossless mode, this is rarely implemented in products. Because of this, JPEGs are not ideal for photos or other images that require high-fidelity reproduction.
The file extension is named after the Joint Photographic Experts Group, a sub-committee of ISO that helped to create this still picture coding standard. The word “JPEG” is sometimes used interchangeably with the term jpg, but this is misleading. The jpg extension was originally required to prevent Microsoft Windows from exceeding its 3-letter limit for file extensions.
To reduce the file size, the pixel data is first resampled to half its original size. Then, the chrominance channels are downsampled to a quarter of their original size. This step results in some loss of quality, but the visual changes are often not noticeable.
JPEG is one of the most popular file formats on the Internet due to its compression and universal browser/OS support. It is not the best choice for images with a lot of text, however, as it can lead to poor text readability because it uses lossy image compression. If you’re working with images that need to be edited frequently, it is recommended that you use a different format such as PNG or GIF.
JPEG files are raster images, which are defined by geometric shapes like polygons, lines and curves, circles and rectangles. They can have various color gradations and are the Web standard for images found on the Web. JPEGs are perfect for photos and artwork with smooth, flowing edges.
