Lossless compression reduces file size without losing image quality. It uses algorithms to eliminate statistical redundancy in data. It's suitable for text, PNG, and GIF image formats that require top-notch quality.

Though you may not be able to easily detect the quality loss, lossy compression might harm your project in the long run. It is mostly recommended for JPEG image format, audio, and video where some data loss is acceptable.
