PPT to PDF API

Endpoint

Authentication is optional for guests and recommended for production. Send either an API key or a JWT access token as a Bearer token. Authenticated requests deduct 2 credits from your balance; failed conversions are refunded. See Authentication for details.

The same request in every supported language. Each example uploads a file and prints the downloadUrl from the response.

curl -X POST https://api.fileswitch.co/api/v1/converter/ppt-to-pdf \
  -H "Authorization: Bearer fc_YOUR_API_KEY" \
  -F "file=@input.ppt"

Parameters

Send file plus any optional options. Every option is optional and falls back to its default when omitted.

{
  "file": "input.ppt",
  "pageRange": ""
}
