Encrypt Link

Encrypt Link turns the URL text into ciphertext for the matching Decrypt Link tool. The output is text, not a clickable destination, and it does not change the destination site's own access controls.

1. Paste the URL you want to protect.
2. Enter a passphrase (or generate one).
3. Test the encrypted value in Decrypt Link, then share it separately from the passphrase.

The full URL string is encrypted with your passphrase. The ciphertext does not display the destination, but the surrounding message or sharing service may still reveal context. Encryption does not change the destination site's access controls.

• Send the encrypted link and passphrase in separate messages or channels.
• Copy as plain text to avoid auto-linking or formatting changes.
• Use short-lived links or expiring access when possible.

• Wrong passphrase or missing characters.
• Extra whitespace or line breaks added by chat apps.
• Truncated links or characters replaced by auto-formatting.

Use Encrypt Link when you need to encrypt a URL string and keep its destination out of the message text. Anyone who obtains the ciphertext and passphrase can recover it. For general text, use the Encrypt Tool.

URL encoding escapes characters so a link can be represented in a URL-compatible form. Encryption turns the destination string into ciphertext for someone who has the passphrase. If you only need to make a URL safe for transport, use the URL Encoding and Decoding Guide.

Open the Decrypt Link tool and enter the encrypted link and the same passphrase used to encrypt it.

Need to share encrypted text instead? Use Encrypt Text Online and copy a share link after encryption.
