Vectorize API

Convert raster images into clean, scalable vector graphics (SVG) with AI-powered vectorization models through Runware's API.

Introduction

Vectorization converts raster images (PNG, JPG, WEBP) into scalable vector graphics (SVG). Unlike raster images that lose quality when scaled, vector graphics maintain perfect clarity at any size, making them ideal for logos, icons, illustrations, and design assets that need infinite resolution with minimal file size.

Request

Our API always accepts an array of objects as input, where each object represents a specific task to be performed. The structure of the object varies depending on the type of the task. For this section, we will focus on the parameters related to the vectorization task.

The following JSON snippet shows the basic structure of a request object. All properties are explained in detail in the next section.

[
  {
    "taskType": "vectorize",
    "taskUUID": "550e8400-e29b-41d4-a716-446655440010",
    "model": "recraft:1@1",
    "outputType": "URL",
    "outputFormat": "SVG",
    "inputs": {
      "image": "c64351d5-4c59-42f7-95e1-eace013eddab"
    }
  }
]

taskType

string required

The type of task to be performed. For this task, the value should be vectorize.

taskUUID

string required UUID v4

When a task is sent to the API you must include a random UUID v4 string using the taskUUID parameter. This string is used to match the async responses to their corresponding tasks.

If you send multiple tasks at the same time, the taskUUID will help you match the responses to the correct tasks.

The taskUUID must be unique for each task you send to the API.

outputType

"base64Data" | "dataURI" | "URL" Default: URL

Specifies the output type in which the image is returned. Supported values are: dataURI, URL, and base64Data.

  • base64Data: The image is returned as a base64-encoded string using the imageBase64Data parameter in the response object.
  • dataURI: The image is returned as a data URI string using the imageDataURI parameter in the response object.
  • URL: The image is returned as a URL string using the imageURL parameter in the response object.

outputFormat

"SVG" required

Specifies the output vector format for the vectorized result.

Available values:

  • SVG: Scalable Vector Graphics format (currently the only supported format).

webhookURL

string

Specifies a webhook URL where JSON responses will be sent via HTTP POST when generation tasks complete. For batch requests with multiple results, each completed item triggers a separate webhook call as it becomes available.

Webhooks can be secured using standard authentication methods supported by your endpoint, such as tokens in query parameters or API keys.

// Basic webhook endpoint
https://api.example.com/webhooks/runware

// With authentication token in query
https://api.example.com/webhooks/runware?token=your_auth_token

// With API key parameter
https://api.example.com/webhooks/runware?apiKey=sk_live_abc123

// With custom tracking parameters
https://api.example.com/webhooks/runware?projectId=proj_789&userId=12345

The webhook POST body contains the JSON response for the completed task according to your request configuration.

deliveryMethod

"sync" | "async" required Default: sync

Determines how the API delivers task results. Choose between immediate synchronous delivery or polling-based asynchronous delivery depending on your task requirements.

Sync mode ("sync"):

Returns complete results directly in the API response when processing completes within the timeout window. For long-running tasks like video generation or model uploads, the request will timeout before completion, though the task continues processing in the background and results remain accessible through the dashboard.

Async mode ("async"):

Returns an immediate acknowledgment with the task UUID, requiring you to poll for results using getResponse once processing completes. This approach prevents timeout issues and allows your application to handle other operations while waiting.

Polling workflow (async):

  1. Submit request with deliveryMethod: "async".
  2. Receive immediate response with the task UUID.
  3. Poll for completion using getResponse task.
  4. Retrieve final results when status shows "success".

When to use each mode:

  • Sync: Fast image generation, simple processing tasks.
  • Async: Video generation, model uploads, or any task that usually takes more than 60 seconds.

Async mode is required for computationally intensive operations to avoid timeout errors.

Specifies a URL where the generated content will be automatically uploaded using the HTTP PUT method. The raw binary data of the media file is sent directly as the request body. For secure uploads to cloud storage, use presigned URLs that include temporary authentication credentials.

Common use cases:

  • Cloud storage: Upload directly to S3 buckets, Google Cloud Storage, or Azure Blob Storage using presigned URLs.
  • CDN integration: Upload to content delivery networks for immediate distribution.
// S3 presigned URL for secure upload
https://your-bucket.s3.amazonaws.com/generated/content.mp4?X-Amz-Signature=abc123&X-Amz-Expires=3600

// Google Cloud Storage presigned URL
https://storage.googleapis.com/your-bucket/content.jpg?X-Goog-Signature=xyz789

// Custom storage endpoint
https://storage.example.com/uploads/generated-image.jpg

The content data will be sent as the request body to the specified URL when generation is complete.

ttl

integer Min: 60

Specifies the time-to-live (TTL) in seconds for generated content when using URL output. This determines how long the generated content will be available at the provided URL before being automatically deleted.

This parameter only takes effect when outputType is set to "URL". It has no effect on other output types.

includeCost

boolean Default: false

If set to true, the cost to perform the task will be included in the response object.

inputs

object

Configuration object containing the input image to be vectorized.

Object properties:

  • image (string, required): The raster image to convert to vector format.

The image can be specified in one of the following formats:

  • An UUID v4 string of a previously uploaded image or a generated image.
  • A data URI string representing the image. The data URI must be in the format data:<mediaType>;base64, followed by the base64-encoded image. For example: data:image/png;base64,iVBORw0KGgo....
  • A base64 encoded image without the data URI prefix. For example: iVBORw0KGgo....
  • A URL pointing to the image. The image must be accessible publicly.

Supported formats are: PNG, JPG and WEBP.

model

string required

We make use of the AIR system to identify vectorization models. This identifier is a unique string that represents a specific model.

Response

Results will be delivered in the format below.

{
  "data": [
    {
      "taskType": "vectorize",
      "taskUUID": "550e8400-e29b-41d4-a716-446655440010",
      "imageURL": "https://im.runware.ai/image/vectorized-output.svg",
      "cost": 0.01
    }
  ]
}

taskType

string

The API will return the taskType you sent in the request. In this case, it will be vectorize. This helps match the responses to the correct task type.

taskUUID

string UUID v4

The API will return the taskUUID you sent in the request. This way you can match the responses to the correct request tasks.

imageUUID

string UUID v4

A unique identifier for the output image. This UUID can be used to reference the image in subsequent operations or for tracking purposes.

The imageUUID is different from the taskUUID. While taskUUID identifies the request, imageUUID identifies the specific image output.

imageURL

string

If outputType is set to URL, this parameter contains the URL of the image to be downloaded.

If outputType is set to base64Data, this parameter contains the base64-encoded image data.

imageDataURI

string

If outputType is set to dataURI, this parameter contains the data URI of the image.

cost

float

if includeCost is set to true, the response will include a cost field for each task object. This field indicates the cost of the request in USD.
