Format conversion: The tool outputs JPEG, PNG, or WebP with optimal settings.
Quality optimization: The tool uses binary search on the quality parameter for the best visual result.
Batch processing: The tool resizes multiple files at once.
Progressive encoding: The tool uses progressive JPEG for smaller file sizes.
