Overview

The Image Upload API from APILayer lets you upload, store, and optimize images in the cloud via a simple REST interface. It handles tasks like resizing, compression, and format conversion so you do not need to set up your own image-processing server. Beginners can use it to add image hosting to their projects with just an API key.

💡

Beginner Tip

Always send your image as multipart/form-data in the request body rather than base64 to avoid payload size issues. Keep your API key in an environment variable and never hardcode it in client-side code.

Available Data

photographer credit
