PNG Compression
PNG compression is a lossless data compression technique used to reduce the file size of PNG (Portable Network Graphics) images without degrading visual quality. It employs algorithms like DEFLATE, which combines LZ77 compression and Huffman coding to remove redundant data while preserving all original image information. This makes PNG compression ideal for graphics requiring high fidelity, such as logos, icons, and screenshots.
Developers should learn PNG compression to optimize web performance by reducing image file sizes, which decreases page load times and bandwidth usage. It is essential for applications where image quality must be preserved, such as in graphic design tools, medical imaging, or archival systems. Understanding compression settings and tools helps balance file size and quality for efficient storage and transmission.
