## Direct answer

Use Safe to email PDF for a privacy score, then Confidential Send to redact, clean, watermark, and encrypt locally before you attach.

## Introduction

Sensitive attachments fail in two ways: they leak data, or they bounce on size. Fix both on your device.

## Steps

1. Run Safe to email / privacy checker.
2. Redact PII and Deep Clean as needed.
3. Compress for Gmail or Outlook if oversized.
4. Optional encrypt via Confidential Send, then attach.

## Privacy receipt

Download a local receipt with hashes if you want a personal record of steps — not a third-party certificate.

## Limits

- Recipient still needs the password if you encrypt.
- Email itself is not an end-to-end vault unless you add more controls.

## FAQ

### Is Confidential Send private?

It runs in your browser on mypdf — no file upload to us.

### Size and privacy together?

Yes — compress and clean, then send.

### AI paste instead of email?

Use Sanitize for AI — different threat model.
