Compression Techniques
- imagemin-svgo:
imagemin-svgo optimizes SVG files by removing unnecessary elements, attributes, and metadata, streamlining the SVG code to reduce file size without affecting the visual output of the image.
- imagemin-gifsicle:
imagemin-gifsicle employs advanced algorithms to optimize GIF files, reducing their size through techniques like frame removal and color palette reduction, which can significantly lower the file size while preserving animation quality.
- imagemin-pngquant:
imagemin-pngquant uses lossy compression to reduce the number of colors in PNG images, which can drastically decrease file sizes. It intelligently selects the optimal color palette to maintain visual fidelity while minimizing size.
- imagemin-jpegtran:
imagemin-jpegtran utilizes lossless compression methods that rearrange the data in JPEG files without losing any quality. This ensures that the images retain their original appearance while being smaller in size.
- imagemin-webp:
imagemin-webp converts images to the WebP format, which uses both lossy and lossless compression techniques to achieve smaller file sizes compared to traditional formats, while maintaining high image quality.
