NullPaste

Frequently asked questions

Everything you might want to know about creating and sharing pastes on NullPaste. Still stuck? The about page covers the basics, or read the guides.

Is NullPaste really anonymous?
Yes. There are no accounts and no sign-up. We don't run analytics or third-party trackers, and raw IP addresses are never stored — rate limiting uses a hashed (HMAC-SHA256) identifier instead.
How long does a paste last?
You choose: 10 minutes, 1 hour, 1 day, 1 week, or never. Timed pastes are deleted automatically once they expire. You can also enable burn-after-read so the paste is destroyed after a single view.
What is burn-after-read?
A burn-after-read paste is deleted permanently the first time it is opened. It's useful for one-time secrets or links you only want a single person to see.
Can I password-protect a paste?
Yes. Add an optional password and only people who know it can open the paste. Passwords are hashed with Argon2 on the server. For stronger privacy, enable end-to-end encryption, which encrypts the content in your browser and keeps the key only in the share link.
How do I delete a paste?
Timed and burn-after-read pastes disappear on their own. Pastes set to never expire come with a one-time delete code shown right after creation — save it, then use it to remove the paste whenever you like.
What can I paste, and how large can it be?
Any plain text or source code, up to 1 MB per paste. Code is shown with Shiki syntax highlighting and the language is auto-detected, or you can set it yourself.
