How it works

  1. 01

    Write or paste

    Drop in plain text or source code — up to 1 MB. The language is auto-detected for syntax highlighting, or set it yourself.

  2. 02

    Choose how it lasts

    Pick an expiry from 10 minutes to never, or turn on burn-after-read so the paste self-destructs after one view. Add a password or end-to-end encryption if you want.

  3. 03

    Share the link

    Get a short URL to share anywhere. No account, no tracking. Pastes set to never expire include a one-time delete code so you stay in control.

Frequently asked questions

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.
Is NullPaste free?
Yes, completely free. NullPaste is a free anonymous pastebin — there are no plans, no limits on the number of pastes you create, and no account required.
Do I need an account to use NullPaste?
No account is needed. NullPaste is designed as a pastebin without sign-up — just open the site, write your paste, and share the link instantly.
