# Tinify API client for Node.js

A lightweight Node.js client for the Tinify API, used for [tinypng API](https://tinypng.com) and [TinyJPG](https://tinyjpg.com). This library lets you intelligently **compress**, **resize**, **convert**, and **store** images (AVIF, WebP, JPEG, PNG) with minimal effort. Read more at [http://tinify.com](http://tinify.com).

## 🚀 Features

- Compress and optimize images in AVIF, WebP, JPEG, and PNG formats
- Resize with intelligent cropping
- Convert between formats
- Preserve metadata (copyright, GPS, creation time)
- Upload directly to Amazon S3, Google Cloud Storage, or custom S3/Azure storage
