# CBZOptimizer # CBZOptimizer
CBZOptimizer is a Go-based tool designed to optimize CBZ (Comic Book Zip) files by converting images to a specified format and quality. This tool is useful for reducing the size of comic book archives while maintaining acceptable image quality. CBZOptimizer is a Go-based tool designed to optimize CBZ (Comic Book Zip) and CBR (Comic Book RAR) files by converting images to a specified format and quality. This tool is useful for reducing the size of comic book archives while maintaining acceptable image quality.
**Note**: CBR files are supported as input but are always converted to CBZ format for output.
## Features ## Features
- Convert images within CBZ files to different formats (e.g., WebP). - Convert images within CBZ and CBR files to different formats (e.g., WebP).
- Support for multiple archive formats including CBZ and CBR (CBR files are converted to CBZ format).
- Adjust the quality of the converted images. - Adjust the quality of the converted images.
- Process multiple chapters in parallel. - Process multiple chapters in parallel.
- Option to override the original CBZ files. - Option to override the original files (CBR files are converted to CBZ and original CBR is deleted).
- Watch a folder for new CBZ files and optimize them automatically. - Watch a folder for new CBZ/CBR files and optimize them automatically.
