How to share notes safely
Sharing a note with Notepad Free is quick, but understanding how it works helps you choose the right option for each situation. Here is everything you need to know about link sharing, password protection and keeping shared notes private.
How link-based sharing works
When you press Share, Notepad Free encodes your note title and content directly into a URL — entirely in your browser. Nothing is sent to a server to create the link. When the recipient opens the link, their browser decodes the content and displays the note. There is no central database that could be breached, no expiry date we set and no account required on either side. The link is self-contained: the note travels with it. The implication is that anyone who has the link can read the note, so share it only over channels you trust.
When to use password protection
If the note contains personal information, confidential plans or anything only one person should see, add a password before sharing. Tick Protect with a password in the share dialog, enter a password, and the note is encrypted with AES-GCM in your browser before being encoded into the link. The password is never part of the URL — only the encrypted content is. Send the link through one channel and the password through a different one for the strongest protection. Even if the link is intercepted or forwarded, the note is unreadable without the password.
Sharing on different platforms
Notepad Free share links work anywhere a URL works: email, WhatsApp, Telegram, Slack, Discord, social media or a simple paste into a document. Very long notes produce very long URLs — some platforms truncate links or wrap them in preview boxes that may interfere. For very long notes, download as a plain text or PDF file and share the file instead. Password-protected links are safer to post in group chats, since a platform that previews the URL cannot decrypt the note.
What not to include in a shared note
Even with a password, think carefully before encoding highly sensitive data — login credentials, financial details, medical records — into a shared link. The encryption is strong, but the security of the exchange depends on how carefully you share the link and the password. For highly sensitive material, use a dedicated end-to-end-encrypted messaging tool instead. For everyday collaboration — drafts, lists, snippets, reference material — sharing by link is fast, convenient and private enough for most purposes.
