Upload file API

ImageKit.io allows you to upload a file (image and non-image) via API. Based on your requirement, you can either:
1.​Upload file from a server using private API key-based authentication, or
2.​Upload file from client-side (in Javascript, or Android or iPhone app) using signature-based authentication.
Both methods use the same endpoint, but there is a slight change in the request bodies.
File size limit
The maximum upload file size is limited to 25MB.
