Zero Retention PDF
Engine.
Enterprise-grade HTML to PDF conversion with absolute data neutrality. Zero Retention processes your data in isolated RAM and purges it the microsecond the stream closes.
The Zero Retention PDF Shield
Engineered for Fintech and Healthtech compliance. We do not use persistent storage (HDD/SSD). Every conversion happens in an ephemeral RAM disk that is hardware-wiped after every request.

Implementation
// Initialize client
const client = require('@zeroretention/sdk');
// Generate Zero Retention PDF
const pdf = await client.render({
html: '<h1>Hello Secure World</h1>',
options: {
retention: 0, // Instant RAM purge
encryption: 'AES-256-GCM',
password: 'secure_pass_123', // Enterprise encryption
headerTemplate: '<div style="font-size:10px">Confidential</div>'
}
});
pdf.pipe(res); // Data leaves RAM, gone forever.# Initialize client
import zeroretention
client = zeroretention.Client(api_key='sk_live_...')
# Generate Zero Retention PDF
pdf_stream = client.render(
html='<h1>Hello Secure World</h1>',
options={
'retention': 0, # Instant RAM purge
'encryption': 'AES-256-GCM',
'password': 'secure_pass_123',
'headerTemplate': '<div style="font-size:10px">Confidential</div>'
}
)
# Stream directly to response

The Zero Retention PDF API requires an API key for all requests. Your API key must be passed in the x-api-key header.

Payload Parameters
html(string, required) - The raw HTML string to convert.password(string, optional) - AES-256 password to encrypt the PDF.headerTemplate(string, optional) - HTML template for the PDF header.footerTemplate(string, optional) - HTML template for the PDF footer.
Privacy & Security
Ephemeral Processing
All HTML payloads are processed entirely in RAM. We utilize headless chromium instances connected via secure websocket pipes, ensuring data never touches a physical disk.
Zero Retention
The generated PDF buffer is piped directly back to the requesting client. Once the TCP stream closes, the RAM allocation is purged instantly.
