Send Large PDF Documents Too Big for Email

Why standard email fails for Large PDF Documents

Legal, architecture, and medical PDFs contain embedded high-DPI scans that push message sizes past mail server quotas.

Confidentiality of Legal Documents: Sending confidential legal briefs or tax audits over standard email exposes them to plaintext interception. LimeShare's zero-knowledge links keep legal data airtight.

Best practices for sending Large PDF Documents

  • Always add a password for sensitive legal, financial, or medical PDF documents.
  • Enable 'Burn after first download' when sharing single-recipient sensitive contracts.
  • Recipients can preview PDF text and vector pages directly in browser.

Frequently asked questions

Can LimeShare read or index the text in my PDF?

No. The PDF is encrypted locally on your device with AES-256 before any byte touches the network. We cannot OCR, index, or view your document.

Are digital signatures in the PDF preserved?

Yes. Digital PKI signatures, form fields, and cryptographic seals remain 100% valid because the file is transmitted byte-for-byte.
