A practical guide for graphic designers and front-end developers on choosing the right compression algorithm.
1. The Technical Distinction Between Lossless and Lossy
Lossless compression reconstructs the original pixel data bit-for-bit without discarding color information. Lossy compression eliminates imperceptible high-frequency color variations to achieve drastic size reductions.
2. Handling Transparency: Why WebP Replaces PNG
WebP supports lossy RGB compression combined with lossless alpha transparency. This unique capability produces transparent PNG-style graphics at up to 75% smaller file sizes than traditional 24-bit PNGs.
