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 permanently deleted after its first read. Opening the link shows a confirmation first — reading only happens after an explicit click, so link-preview bots in Slack or Discord can't consume it. Note that whoever opens the link first is the one who burns it, and a reader can still copy the content.
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. A password controls access — the server still stores the content. For content the server itself should never be able to read, enable end-to-end encryption, which encrypts in your browser and keeps the key only in the share link's #key= fragment.
How do I delete a paste?
Every paste comes with a one-time delete code shown right after creation — save it, then use it to remove the paste at any time, no account needed. Timed and burn-after-read pastes also disappear on their own.
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.
Can I share files, photos, or other binary content?
NullPaste is built for plain text and code, not files. For photos, videos, PDFs, archives, or any other file, use NullDrop (nulldrop.org) — the file-sharing sibling in the same privacy-first family, with expiring links and full browser-side encryption.
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.
Can I share code anonymously?
Yes. NullPaste is an anonymous pastebin built for sharing code and text without any identity attached. No login, no email, no raw IP addresses stored — just a link.
What is the best free pastebin with no account?
NullPaste is a free anonymous pastebin that requires no account or sign-up. All features — expiry, burn-after-read, password protection, end-to-end encryption, and syntax highlighting — are available for free without registration.
How do I create a temporary paste that auto-deletes?
Set the Expires option to 10 minutes, 1 hour, 1 day, or 1 week when creating a paste. NullPaste deletes it automatically once the time is up. Alternatively, enable burn-after-read to delete the paste the moment it is first viewed.
Is NullPaste a good hastebin alternative?
Yes. NullPaste offers everything hastebin did — no account, instant paste, syntax highlighting — plus features hastebin never had: custom expiry, burn-after-read, password protection, end-to-end encryption, and a delete code. It is also actively maintained, unlike hastebin.com which has been unreliable for years.
Can I use NullPaste to share code with syntax highlighting?
Yes. NullPaste uses Shiki for syntax highlighting and supports 100+ programming languages. The language is auto-detected from your code, or you can set it manually. Share a clean, highlighted link in under 10 seconds — no account required.
Is NullPaste a secure pastebin?
NullPaste has several layers of security: no IP addresses are stored, paste pages have noindex robots directives, there are no analytics or trackers, and optional browser-side end-to-end encryption means the server never sees the key for encrypted pastes. For sensitive content, enable encryption and burn-after-read.
How do I share text online without an account?
Open NullPaste, type or paste your text, and click Create Paste. You get a shareable link in seconds — no account, no email, no sign-up. The link works in any browser on any device.
