Upload file API

ImageKit.io allows you to upload a file (image and non-image) via API.
API v1
Based on your requirement, you can either:
  1. 1.
    Upload file from a server using private API key-based authentication, or
  2. 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.
API v2
Based on your requirement, you can either:
  1. 1.
    Upload file from a server using private API key-based authentication, or
  2. 2.
    File upload from client-side (secure) (in Javascript or any client side application) using JSON Web Token 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 on the free plan. On paid plan, this limit is 300MB for video files.

Allowed file types for uploading

ImageKit.io supports the uploading of a wide range of file types, accommodating various formats from media files to documents.

How file types are identified

  1. 1.
    Binary files: Binary files, such as images, videos, and executables, are identified using the 'magic number'.
  2. 2.
    Text files: Text files, such as HTML, CSS, and JavaScript, are identified using the file extension.
  3. 3.
    Text files without extension: When a text file is uploaded without an extension, it is categorized under the content-type `application/octet-stream.’

Bulk file upload

The upload API can upload one file at a time. To upload files in bulk, write a program to loop through files and call upload API repeatedly. Leverage ImageKit.io server-side SDKs to implement bulk upload program.
