Lossless compression is a data reduction technique that allows the original data to be perfectly reconstructed from the compressed data. In the context of digital images, this method reduces file size without any loss of quality, preserving all original details.

Formats like PNG and GIF utilize lossless compression, making them suitable for images requiring high fidelity, such as logos or graphics with text. Implementing lossless compression is essential when image integrity is paramount, ensuring that visual assets maintain their quality across various platforms.
