SVG to PNG API: Rasterize SVG Vectors to PNG at Any Resolution

Authentication

Every request is authenticated with your Pixazo API key in the Ocp-Apim-Subscription-Key header — the same key across every Pixazo endpoint.

SVG to PNG generate request

SVG is perfect for scalable UI and print, but countless destinations, email templates, marketplace thumbnails, Open Graph images, and legacy image pipelines, only accept raster formats. Rasterizing to PNG produces a fixed-resolution bitmap while preserving the alpha channel, so logos and icons stay transparent against any background. Pixazo's /media-tools/v1/svg-rasterize endpoint renders the vector geometry and returns a PNG. Because PNG supports lossless transparency, it is the natural raster target for graphics that must sit cleanly over other content. This endpoint is currently in preview rather than general availability.

Endpoint: POST https://gateway.pixazo.ai/media-tools/v1/svg-rasterize

Request Code

curl -X POST 'https://gateway.pixazo.ai/media-tools/v1/svg-rasterize' \
  -H 'Ocp-Apim-Subscription-Key: YOUR_API_KEY' \
  -H 'Content-Type: application/json' \
  -d '{"svg_url":"https://example.com/input.svg","to_format":"png","width":1024}'

Output

{
  "request_id": "req_9f3c1a7b2e",
  "status": "QUEUED",
  "polling_url": "https://gateway.pixazo.ai/v2/requests/status/req_9f3c1a7b2e"
}

Webhook (Optional)

Instead of polling, include a webhook_url in the request body and Pixazo will POST the completed job payload to that URL when the conversion finishes. The webhook body is identical to the completed-status response shown under Retrieving Results.

Response

Every request returns a request_id immediately with a QUEUED status. Use the polling_url (or a webhook) to retrieve the finished file.

{
  "request_id": "req_9f3c1a7b2e",
  "status": "QUEUED",
  "polling_url": "https://gateway.pixazo.ai/v2/requests/status/req_9f3c1a7b2e"
}

Request Headers

Response Handling

The submit call returns one of the HTTP status codes below. A 202 means the job was accepted — everything else is an error you should handle.

Error Responses

Errors return a JSON body with a machine-readable code and a human-readable message.

{
  "request_id": "req_9f3c1a7b2e",
  "status": "FAILED",
  "error": {
    "code": "INSUFFICIENT_BALANCE",
    "message": "Your account balance is too low to process this request."
  }
}

Retrieving Results

Poll the status endpoint until the job reaches COMPLETED (or FAILED).

curl 'https://gateway.pixazo.ai/v2/requests/status/req_9f3c1a7b2e' \
