How Freelancers Can Deliver Files to Clients Securely

If you freelance, you probably send files to multiple clients every week. Designs, code, videos, reports — how you deliver them matters more than you'd think. The wrong method can lead to security incidents or payment disputes.

Problems with Common Methods

Messengers (iMessage, WhatsApp)

Fast and convenient, but:

• ❌ Files are stored permanently on the messenger's servers
• ❌ Risk of sending to the wrong chat
• ❌ Recipients can easily forward to others

Email

Formal, but:

• ❌ 25MB attachment limit
• ❌ Stored as plaintext on mail servers
• ❌ Anyone with the email can immediately download

Google Drive

Good for collaboration, but:

• ❌ Sign-up required
• ❌ Wrong permissions can expose files to anyone
• ❌ Clients with full free tier can't download

What Freelancers Should Consider

1. Preview Before Payment, Original After

Sending watermarked previews first and full files only after payment confirmation is a common pattern.

2. One-Time Download

Links that auto-expire after the recipient downloads are ideal.

3. Password Protection

Even if the link leaks, no one can access without the password.

4. Expiration Time

After the project is done, files should auto-delete after a set time to clarify responsibility.

LOCK.PUB offers features well-suited for freelancers.

Preview Delivery (Before Payment)

1. Upload a watermarked preview file
2. Set a password
3. Send the link + password to the client

Final Delivery (After Payment)

1. Upload the original file
2. Set a new password (different from the preview)
3. Pro users can set an expiration (e.g., 7 days)
4. Send link + password to the client

• ✅ No sign-up needed (for client either)
• ✅ End-to-end encryption
• ✅ Free password protection
• ✅ Pro: expiration time, download limits

Client Handling Tips

Separate Channels for Link and Password

Send the link via email and the password via phone or text. Even if one channel is compromised, you're safe.

Change Password After Payment

When delivering the final file, use a different password from the preview. People who know the preview password can't access the final file.

Confirm Download

Send a "Let me know once you've downloaded" message. It serves as evidence in case of disputes.
