- Compress a WebP file with default settings (q = 75) to the [o]utput file:
- Compress a WebP file with default settings (lossy compression, q = 75) to the [o]utput file:
`cwebp {{path/to/image_file}} -o {{path/to/output.webp}}`
- Compress a WebP file with the best [q]uality and largest file size:
- Compress a WebP file with the best lossy compression [q]uality and largest file size:
`cwebp {{path/to/image_file}} -o {{path/to/output.webp}} -q {{100}}`
- Compress a WebP file with the worst [q]uality and smallest file size:
- Compress a WebP file with the worst lossy compression [q]uality and smallest file size:
`cwebp {{path/to/image_file}} -o {{path/to/output.webp}} -q {{0}}`
- Compress a WebP file and apply resize to image:
- Compress a WebP file with lossless compression and smallest possible file size:
`cwebp {{path/to/image_file}} -o {{path/to/output.webp}} -z 9`
- Compress a WebP file and apply resize to image (if width or height are 0, scaling preserves aspect ratio):
`cwebp {{path/to/image_file}} -o {{path/to/output.webp}} -resize {{width}} {{height}}`
