webp-converter-cli, which is a free and open-source option, as a best JPG to WebP converter for your needs. This tool is a Python-based command-line utility designed for converting images to WebP format. Its core features include:
- Format Support: It supports converting JPG, PNG, and MPO images to WebP.
- Quality Control: You can adjust the output quality for lossy compression on a scale of 1-100 (the default is 80).
- Batch Processing: It can handle multiple files at once, processing entire directories or files that match specific glob patterns (like *.jpg).
- Error Handling: Includes options like --continue-on-error to ensure the process doesn't stop if a single file conversion fails.
If these features align with your needs, webp-converter-cli is a strong candidate to be the best JPG to WebP converter for you, given its flexibility and price (free). It does require some comfort with the command line, as there is no graphical interface.
While functional, there are a few important points to consider about this tool:
- Status: The version described on the official PyPI page is 1.0.0, and the GitHub repository appears to be a "just for fun" project from 2016. It hasn't been updated recently, which could mean it's missing support for newer features or might not be perfectly compatible with the latest operating systems.
- Dependencies: It requires Python and pip to be installed on your system.
