Video about PNG vs JPG
The main differences between the PNG and the JPG.
The main differences between the PNG and the JPG are as follows:
Compression: PNG uses lossless compression, preserving all image data, while JPG uses lossy compression, which sacrifices some image quality for smaller file sizes.
Transparency: PNG supports transparency with an alpha channel, allowing for partially transparent images, whereas JPG does not support transparency.
Color Depth: PNG supports higher color depths, including 24-bit RGB and 32-bit RGBA, while JPG typically supports 24-bit RGB.
File Size: PNG files are generally larger due to lossless compression, while JPG files are smaller due to lossy compression.
Use Cases: PNG is preferred for images requiring high quality and transparency, such as logos and graphics, while JPG is commonly used for photographs and web images where file size is a concern.

1. When to choose PNG:
PNG is better for images that require transparency, such as logos or graphics with sharp edges. It is also ideal for images that need to be edited multiple times without losing quality, as PNG is a lossless format.
2. When to choose JPG:
JPG is better for photographs or images with complex color gradients, as it offers a good balance between file size and quality. It is also suitable for web use where smaller file sizes are preferred to reduce loading times.
