About

Alic makes it simple to compress images. It's a great tool for quickly compressing images for the web, or to share with clients.

Why compress images?

• Faster load times
• Less bandwidth usage
• Better SEO
• Better user experience

And security: Many cameras and phones embed metadata in images, which can include location, camera model, and other sensitive information. Alic can remove this metadata for you.

Supported image formats:

• JPEG
• PNG
• WebP
• GIF
• TIFF

Alic is heavily inspired by ImageOptim, but with modern compression algorithms for smaller files and speed. See Differences from ImageOptim.

Installation

1. Download the latest release from the releases page
2. Drag to Applications folder
3. Launch and enjoy!

Usage

Drag and drop images (or folders) into the window, images will automatically start compressing. The compressed images will be saved in the same directory as the original images.

Having trouble? Hover over the status icons for helpful hints!

CLI Usage

The Alic app binary doubles as a CLI. Pass --input to compress images without opening the GUI:

Alic --input /path/to/image.jpg
Alic --input /path/to/images/ --reformat webp --lossy --webp-quality 80

On macOS you can run the binary inside the app bundle:

"/Applications/Alic Image Compressor.app/Contents/MacOS/Alic" --input /path/to/image.jpg

Or create a shell alias for convenience:

alias alic='"/Applications/Alic Image Compressor.app/Contents/MacOS/Alic"'

Run Alic --help for all options. Boolean flags use --flag / --no-flag pairs (e.g. --lossy / --no-lossy). Omitted flags use the selected profile's value.

Flags:

• --input <path> — Input file or directory (required, repeatable)
• --profile <name-or-id> — Profile to use
• --threads <n> — Concurrent image processing (default: 1)
• --recursive / --no-recursive — Recurse into directories (default: recursive)
• --resize <WIDTHxHEIGHT> — Resize images
• --reformat <format> — Convert (jpeg|png|webp|gif|tiff|avif)
• --overwrite / --no-overwrite
• --postfix <text> — Postfix text for output filenames
• --add-postfix / --no-postfix
• --lossy / --no-lossy
• --keep-metadata / --no-keep-metadata
• --keep-timestamps / --no-keep-timestamps
• --background-fill <#RRGGBB> / --no-background-fill
• --jpeg-quality <1-100>
• --png-quality <1-100>
• --webp-quality <1-100>
• --gif-quality <1-100>
• --avif-quality <1-100>
• --help / --version

Differences from ImageOptim

• WebP support
• Super fast: Built with Rust and modern compression magic
• Safe defaults: Original files stay untouched
• Resize option: Scale down those massive images
• Multiple profiles: Save different settings for different needs

Roadmap

• Apple Developer ID signing
• Update checker
• Different optimization levels
• Lossless compression
• Directory support
• Finder context menu
• Image resizing
