imgenc is a basic Base64 image encoder cli tool that takes an image and base64 encodes it to Stdout or a specified file.
brew tap Squwid/homebrew-repo
brew install imgenc
Navigate to downloads page, find the correct architecture/operating system. Set path to the binary and you are ready to go.
Using the CLI tool is extremely easy. Just run the imgenc command with an input file, and an optional output file. If no output file is given, the output will be printed to Stdout.
imgenc <inputFile> <optional outputFile>
Lets say I have an image of my dog called devito.png. I want to Base64 encode it to easily send it through a POST request body as a string.
imgenc devito.png ~/Documents/images/devito-base64.txt
If you have a copy to clipboard command as well, it could be used by giving no output and piping to the clipboard command, with something like this.
imgenc devito.png | cb
