How to Send PDF Files Between Devices
Share multi-page PDF documents, signed contracts, and ebooks across computers and mobile phones without email bounce-backs or cloud links.
Sending PDF documents between computers, smartphones, and tablets can be done directly in your web browser. This ensures sensitive financial records, signed contracts, legal documents, and large ebooks transfer privately without passing through third-party servers.
The privacy and size concerns with PDF sharing
PDF files frequently contain sensitive personal data, such as tax documents, business agreements, medical charts, and architectural blueprints. Sharing these files through traditional channels introduces risks:
- Email bounce-backs: Large architectural scans or image-dense manuals often exceed 25 MB and bounce back from recipient mailboxes.
- Third-party cloud exposure: Uploading private contracts to cloud services exposes them to third-party indexing, account credential breaches, or accidental public link sharing.
