  Image Optimizer CLI client

CLI client for the Image Optimization API

What is ?

Use Image Optimizer for FREE to optimize your pictures file sizes. Improve your performances by using, the 10+ billion images API optimizer. Image Optimizer allows you to use free Image optimization based on API. provides image size reduction based on several advanced algorithms. The API accept JPG, PNG and GIF files up to 5MB.

What is this tool ?

This tool allow you to perform a powerful optimization of one or multiple pictures using a bash (command line) script based on the API.

Getting Started

This tool can optimize one or several pictures. The recursive option is not yet implemented.

  1. Download the tool using this command wget | bash ./
  2. Make the file executable using the following command : chmod +x
  3. Run the optimizer by typing command ./ myfile.jpg


This will require to be executed on a Linux based Operating System (Linux or MacOS). The following packages must be installed on the system

Install on your system

If you're using a Linux system (Debian, CentOS...) you can install after cloning from the GIT repo by typing the following command as root user (or using sudo) :

  • mv /usr/bin/resmushit;chmod +x /usr/bin/resmushit

Your CLI optimizer will be available everywhere on your server/computer by typing resmushit

Usage example

Replace in the examples below resmushit by ./ if you haven't installed the optimizer globally on your machine.

Optimize a picture and create a new optimized picture file

resmushit mypicture.jpg

The optimized file will be named mypicture-optimized.jpg

Optimize a picture and replace the original file

resmushit mypicture.jpg --preserve-filename

Optimize a picture and set a optimization factor

resmushit -q 92 mypicture.jpg

Optimize multiple pictures and export them into a folder

resmushit --output myexportdirectory/ *

**Optimize a folder recursively **

resmushit myfolder -r resmushit /path/to/folder -r resmushit * -r

Optimize a picture and preserve its EXIF data

resmushit mypicture.jpg --preserve-exif


  • -h or --help : display the help menu
  • -v or --version : display the current version of reSmushit CLI client
  • -q <quality> or --quality <quality> : specify the quality factor between 0 and 100 (default is 92).
  • -o <directory> or --output <directory> : specify an output directory (will be created if not present)
  • -r or --recursive : execute the optimization to the folder specified recusively
  • --preserve-filename : avoid to add -optimized in the filename when the image is optimized
  • --preserve-exif : will preserve EXIF data in the file after optimization
  • --notime : avoid to display timer in output
  • --quiet : run in quiet mode
  • --update : perform an auto-upgrade process


All bugs should be reported to :


  • Add "preserve filename" option
  • Add EXIF preservation option
  • Add progress bar mode
  • Add support of recursive optimization
  • Add an installer mode
  • Add an auto-update method based on Git repo
  • Avoid sending to API if file is > 5MB
