How this thing works

anonymous.tools is a folder of HTML, CSS and JavaScript. That's it. There's no server behind it doing the work, no account, no database, no analytics. When you encrypt something here, your own browser does the math, and the result never leaves the tab unless you copy it somewhere yourself.

Don't take my word for it

Press F12, open the Network tab, reload, and use any tool. You'll see the site's own files load and nothing else. No calls home, no fonts from Google, no "anonymous" usage stats.
Load the page, then turn off Wi-Fi or pull the cable. Everything keeps working.
Read the code. It's plain JavaScript with no framework, no minifying and no build step. assets/js/tools/ has one file per section, assets/js/lib/ holds the QR, ZIP, certificate and punycode code I wrote for this.
Every page ships with a Content-Security-Policy that sets connect-src 'none'. Even if a bug tried to send something out, the browser itself would refuse.

What it can't protect you from

A browser extension that can "read and change data on all websites" can read what you type here too, same as anywhere else.
Malware on your computer. If the machine is owned, no website can save you.
A weak password. AES-256 is only as strong as the word you lock it with.
Your own clipboard. Passwords and secrets you copy get wiped after 30 seconds, but Windows clipboard history (Win+V) or a phone keyboard may still keep a copy.
Reading QR codes depends on the browser. Chrome on Android and Mac can; Windows can't yet.

Where things are kept

Nowhere, with one exception: the locked notes, which sit in this browser's local storage, encrypted with your password. Everything else lives in the page's memory and is gone when you close the tab.

The ☠ Wipe button at the top (or Esc three times, fast) clears every field, the clipboard and the page's memory in one go. It doesn't delete the notebook; that has its own button, on purpose.

Shortcuts

What's new

v1.4 · 4 Nov 2026: Ten new tools: encrypt for someone, QR codes, locked notes, document cleaner, style scrubber, email headers, certificates, CSP builder, image squeezer, JSON/CSV/YAML. Tool search, the wipe button, full-screen mode, and the link cleaner now spells out punycode domains so look-alikes are obvious. And this page.
v1.3: Split into separate English and Arabic pages. Strict CSP everywhere. Regex runs in a throwaway worker so a nasty pattern can't freeze the tab. Nine new tools and a pile of small fixes (phone numbers in Arabic digits, emoji in hidden text, cards next to phone numbers).
v1.2: The language switch and a second batch of tools.
v1.1: The dark look and the skull.
v1.0: First version. It was gold. We don't talk about it.

Found a bug, or something that says it's private but isn't? That's the kind of report I want most.
