Embedded Files
Summary:
PNG (Portable Network Graphics) and JPG (Joint Photographic Experts Group) are both image file formats but differ in compression methods and use cases. PNG offers lossless compression, preserving image quality, making it suitable for graphics with text or sharp edges. JPG, using lossy compression, is ideal for photographs, sacrificing some detail for smaller file sizes, making it better for web and photography applications.
Summary:
Image file size refers to the amount of digital storage space an image occupies. It's measured in kilobytes (KB), megabytes (MB), or gigabytes (GB). The file size depends on factors like image dimensions, color depth, and compression level. Larger file sizes have higher quality but require more storage and bandwidth to load. Optimizing file size helps balance image quality with website performance and loading speed.
Summary:
Image dimensions refer to the width and height of an image, typically measured in pixels (px). They determine the physical size and aspect ratio of the image when displayed on a screen or printed. The dimensions directly affect the image's visual appearance and file size. Higher dimensions result in larger file sizes and potentially better image quality, while lower dimensions reduce file size but may sacrifice detail and clarity.
Summary:
Bit depth refers to the number of bits used to represent the color of each pixel in an image or the amplitude of audio samples. In images, higher bit depth allows for more accurate color representation and smoother gradients. In audio, it determines the dynamic range and resolution of sound. Common bit depths include 8-bit, 16-bit, and 24-bit, with higher bit depths providing better fidelity but requiring more storage space.
Summary:
An image watermark is a semi-transparent graphic or text overlay applied to an image to identify its ownership or source. It serves as a visual deterrent against unauthorized use or distribution of the image. Watermarks typically include a logo, copyright symbol, or text such as a website URL or creator's name. They are often positioned discreetly in a corner or throughout the image to minimize interference with viewing while maintaining visibility.
