IP Addresses

PDFBolt uses static IP addresses for all outbound traffic. If your source URLs, webhook endpoints, or S3 buckets are behind a firewall, add these IPs to your allowlist.

Outbound IP Addresses​

IP AddressRegion
49.13.36.211EU (Germany)
5.75.219.91EU (Germany)

All API traffic originates from these addresses, including:

  • URL fetching – when you pass a url parameter, PDFBolt fetches the page from one of these IPs.
  • Webhook delivery – async conversion results are sent to your webhook from these IPs.
  • S3 uploads – when using customS3PresignedUrl, the upload comes from these IPs.

When Do I Need to Allowlist?​

Add these IPs to your firewall if:

  • Your source URLs point to an internal network or a server with IP-based access control.
  • Your webhook receiver only accepts requests from known IPs.
  • Your S3 bucket policy restricts uploads by source IP.

If your URLs are publicly accessible and you don't use webhooks or custom S3 uploads, no allowlisting is needed.

Stability​

These IP addresses are static. If they ever change, updated addresses will be published on this page and all users will be notified in advance.
