jpegoptim is a command-line utility for optimizing and compressing JPEG files, offering lossless optimization via Huffman table optimization and lossy compression via maximum quality factor settings. It supports parallel processing, stdin/stdout, and works with libjpeg, libjpeg-turbo, or mozjpeg.
Use cases
- compress jpeg files without losing quality
- reduce image file sizes for a website
- batch optimize a folder of jpegs
- shrink photos to a target file size
- strip metadata from jpeg images
- convert jpegs to progressive encoding
When to choose
- you need a fast, scriptable CLI for JPEG compression in build pipelines or CI
- you want lossless JPEG optimization with no re-encoding artifacts
- you need batch processing with parallel workers on Linux/macOS/Windows
When to avoid
- you need to optimize PNG, WebP, or other non-JPEG formats
- you want a GUI image optimizer
- you need advanced image editing beyond compression
