Need a desktop tool for bulk image compression

I work with lots of images for web projects and manually compressing them takes forever. Online tools have file size limits and privacy concerns. Need a desktop tool that can batch compress while maintaining good quality and supporting different output formats.

A desktop application that can batch compress images with customizable quality settings and format conversion. Should preserve metadata when needed and provide before/after comparisons.

Batch processing, quality presets, metadata preservation, progress indicators, format conversion (JPG, PNG, WebP), drag-and-drop interface, before/after preview
