API Documentation - OctoSqueeze | Image Compression REST API

Quick Start

Compress your first image in under a minute. All you need is an API key.

cURL

curl -X POST https://api.octosqueeze.com/api/v1/compress \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -F "file=@/path/to/image.jpg" \
  -F "mode=balanced"

Base URL: https://api.octosqueeze.com/api/v1

Authentication

All API requests require authentication using a Bearer token. Include your API key in the Authorization header:

HTTP Header

Authorization: Bearer YOUR_API_KEY

You can generate API keys from your dashboard. Keep your API keys secure and never expose them in client-side code.

Security: Never commit API keys to version control or expose them in frontend code.

Compress Image

POST /api/v1/compress

Compress an image by uploading a file or providing a URL. Returns compression results and a temporary download URL.

Option 1: File Upload

Send a multipart/form-data request with the image file:

HTTP

Host: api.octosqueeze.com
Authorization: Bearer YOUR_API_KEY
Content-Type: multipart/form-data

file: [binary image data]
format: webp
mode: balanced

Option 2: URL

Send a JSON request with an image URL:

JSON

{
  "url": "https://example.com/image.jpg",
  "format": "webp",
  "mode": "balanced"
}

Batch Compression

POST /api/v1/compress-batch

Compress multiple images from URLs in a single request (up to 100 images).

JSON

{
  "items": [
    {
      "url": "https://example.com/image1.jpg",
      "image_id": "my-id-1",
      "options": { "mode": "size", "format": "webp" }
    },

      "image_id": "my-id-2"
    }
  ],
  "options": {
    "mode": "balanced",
