In-Workflow Outbound Attachment Protection (SanitizePDF Pro)

Stop accidental PDF leaks in Gmail and Outlook.
Before you click Send.

Everyday data breaches rarely start with external intrusions. They happen when someone drags the unredacted draft of a contract, tax filing, or CV into an email. SanitizePDF inspects attached PDFs locally inside Gmail and Outlook Web the moment you attach them.

How In-Draft PDF Interception Works

No extra desktop software, proxy certificates, or admin mail-gateway configuration required. Install the browser extension in Google Chrome or Microsoft Edge and compose email normally.

Step 02

Instant Non-Blocking Alert Pill

If for example national IDs, tax numbers, IBANs, contact details, or hidden Author and Creator tags are detected, a compact warning banner summarizes exact match counts per file without stealing typing focus from your email draft.

  • Flags both visible PII and hidden PDF metadata
  • Dismiss in one click or Escape button
Step 03

Preview, Redact & Replace in Draft

Open the preview popup window to review auto-detected boxes, draw custom manual redactions across multiple attached PDFs, and replace the unredacted attachments in your active email draft in one click.

  • Attaches clean flattened PDFs directly to your draft
  • Supports per-file PII and branding rules
Strict Isolation Boundaries

Engineered to Protect Sensitive Inbox Environments

Granting a browser extension access to webmail requires strict technical boundaries. Unlike cloud DLP plugins that route attachments through external inspection APIs, SanitizePDF processes every byte inside your local browser tab.

Your unredacted agreements, medical forms, financial statements, and candidate resumes never leave your machine, keeping compliance teams aligned with EU GDPR and US CCPA data minimization rules.

  • Zero Inbox or Email Body Access Inspects only PDF files actively attached to a compose draft. Never reads incoming emails, message text, subject lines, or recipient lists.
  • Closed Shadow DOM Isolation All warning banners and preview modals render inside an isolated Shadow Root so webmail scripts and styles cannot inspect or interfere with redaction controls.
  • Lazy On-Demand Engine Loading PDF parsing and rasterization libraries load only when a PDF attachment is detected, preserving fast Gmail and Outlook Web startup times.
