Solution

tinypng

API key is required, and the monthly free limit is 500 per email account. For details, see: https://tinypng.com/developers

The cli tool will query the usage of the current month based on the API key and compare it with the number of images that need to be optimized. If the quota cannot complete the task, it will automatically exit.

ENV

You can save your API key in environment TINYPNG_API_KEY. The cli tool will get it from process.env.TINYPNG_API_KEY. Otherwise you need to manually enter it each time.

Example

1. Compress a single file:

img min test.png

2. Recursively compress all WebP, PNG, and JPEG images in the entire directory, and output the log to a file (for tracking failed images):

img min your_relative_dir -l on
