Call the API

Issue a short-lived token, upload to upload_url, then read conversion_id.

Request/Response Flow

2-step

1. Request /api/v1/convert-token with API key

2. Upload PDF using upload_url + convert_token from step 1

3. Use conversion_id for WebSocket progress, or poll result_url for final result

# 1) Issue convert token
curl -X POST \
  -H "Authorization: Bearer YOUR_API_KEY" \
  https://www.pdf2png.xyz/api/v1/convert-token

# 2) Upload file to upload_url
curl -X POST \
  -H "Authorization: Bearer {convert_token}" \
  -F "file=@document.pdf" \
  {upload_url}

Response Example

200 OK

# /api/v1/convert-token response
{
  "convert_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...",
  "expires_in": 300,
  "upload_url": "https://.../convert",
  "ws_url": "wss://.../ws"
}

# upload response
{
  "conversion_id": "abc123",
  "result_url": "https://.../result/abc123"
}

In result_url responses, pages[].data is base64 for each PNG page (not the original PDF). Decode base64 and save as .png files.

Connect to ws_url via WebSocket and send conversion_id to receive page-by-page PNG (base64) stream.

Language Examples

# 1) Issue token
TOKEN_RESPONSE=$(curl -s -X POST \
  -H "Authorization: Bearer YOUR_API_KEY" \
  https://www.pdf2png.xyz/api/v1/convert-token)

UPLOAD_URL=$(echo "$TOKEN_RESPONSE" | jq -r '.upload_url')
CONVERT_TOKEN=$(echo "$TOKEN_RESPONSE" | jq -r '.convert_token')

# 2) Upload file
curl -X POST \
  -H "Authorization: Bearer ${CONVERT_TOKEN}" \
  -F "file=@document.pdf" \
  "${UPLOAD_URL}"

WebSocket Example (Realtime)

# 1) Connect to ws_url
wscat -c "{ws_url}"

# 2) Send conversion_id
> {"conversion_id":"abc123"}

# 3) Receive progress events
< {"status":"processing","progress":42.5}
< {"status":"completed","progress":100}

Final Result via HTTP

# Poll final result (use result_url from upload response)
curl "{result_url}"

# If status=completed, decode pages[].data(base64) and save as .png

Security tip

Never expose API keys in the browser; use them server-side only.
