Edit Image
JPG, short for Joint Photographic Experts Group, is a standard format for compressing and storing digital images. Widely used for photographs and web images, it maintains a certain level of image quality while reducing file size. It primarily uses Discrete Cosine Transform (DCT) for image compression, which helps reduce file size and save storage space. However, some information may be lost during the compression process. JPG is supported by most image viewers and editing programs, making it very convenient for online image sharing. However, it does not support transparency and may not be suitable for images with sharp details or text.
PNG files are widely used raster image file formats on the internet, known for their 'lossless' characteristic. This means that the quality remains undistorted when compressed while maintaining a certain pixel count. Hence, they are ideal for storing high-quality images such as logos, photos, and screenshots, and also support transparency, making them useful for creating web graphics with transparent backgrounds.
One of the advantages of converting JPG to PNG is the preservation of image quality. PNG uses lossless compression, so the quality is maintained even when the image is repeatedly saved. Especially for images requiring sharp boundaries such as text or graphics, PNG is more suitable than JPG. Additionally, PNG fully supports transparency, allowing for the creation of images with transparent backgrounds. However, PNG files are larger in size compared to JPG, and compression for quality is not applied, resulting in greater storage space and bandwidth usage. Moreover, PNG may take longer processing time compared to JPG. Therefore, users should choose the appropriate format based on the purpose of the image and the performance of the website.
