What is a JPEG File?

A JPEG (Joint Photographic Experts Group) file is a digital image file format commonly used to store photographs also graphics with a lot of color and detail. Moreover, JPEG files use lossy compression to reduce the file size, which means that some of the original image data is discarded during the compression process. However, the degree of reduction can be adjusted to find a balance between image quality and file size. Therefore, JPEG files are widely supported by most web browsers, image editing software, and operating systems, making them a popular choice for sharing images online or storing them on digital devices.

What is a PNG File?

PNG (Portable Network Graphics) is a digital image file format that uses lossless compression to store images. Additionally, It means the compression process does not affect the image quality, and the original image data is preserved. PNG files are particularly well-suited for images with transparent backgrounds, as they can support alpha channels for transparency. They are commonly used for graphics, logos, and other pictures that require sharp edges and crisp lines. Moreover, most web browsers support PNG files, image editing software, and operating systems, although some older programs may not help with the format.

What is the Difference Between JPEG and PNG Files?

JPEG (Joint Photographic Experts Group) and PNG (Portable Network Graphics) are both popular file formats used for storing and displaying images, but they have some key differences:

Compression:

JPEG files use lossy compression, which means that some data is discarded during compression to reduce the file size. Additionally it can result in losing image quality, particularly in areas with refined details or sharp edges. PNG files use lossless compression, which retains all the data and preserves image quality.

Transparency:

PNG files enable transparency support, allowing the image to become transparent and reveal the background. Although, JPEG files do not support transparency.

Colour depth:

PNG files support a more comprehensive range of colour depths than JPEG files. In addition, PNG files can store 24-bit RGB or 32-bit RGBA colour images, while JPEG files are typically limited to 8-bit colour.

File size:

JPEG files are typically smaller than PNG files because they use lossy compression. This characteristic makes them ideal for web use and also sharing via email or messaging apps. However, the smaller file size comes at the cost of some loss of image quality.

Use cases:

JPEG files are best for photographs or images with complex colour gradients . Therefore, subtle colour variations, as the lossy compression is less noticeable in these images. PNG files are best for prints with sharp edges or areas of transparency, for example logos, icons, or graphics with text.
