tinifier is a CLI tool for compressing images using the TinyPNG API, with parallel processing to speed up the workflow.
This is free and open source software.
Key Features
- Compress images in parallel (configurable number of threads).
- Support for multiple API keys (automatically switches if a key exceeds its quota).
- Automatic retries for failed operations.
- Recursive search for images in directories (configurable file extensions).
- Skip files if the difference between the original and compressed file sizes is below a specified percentage.
- Preserve the original file modification date/time (including EXIF metadata), ensuring correct photo ordering (e.g., from smartphones) after compression.
