Stop Pasting Your Base64 Strings into Random Websites 🛑

I see developers do this all the time: they need to decode a Base64 string (like a Basic Auth header or a part of a JWT), so they Google "base64 decoder," click the first result, and paste their sensitive data.

⚠️ The Hidden Risk

Do you know where that data goes?
Most "free" online tools send your keystrokes to their backend server. Even if they claim not to store it, your sensitive string is likely passing through their access logs, analytics, or third-party trackers.

If you are pasting production API keys or credentials, you are effectively leaking them.

The Secure Alternative 🔒

You need a tool that runs 100% Client-Side. This means the JavaScript runs in your browser, and the data never travels over the internet.

I built the PaPiv Base64 Tool exactly for this reason.

• Offline Ready: Works even if you disconnect your internet.
• Instant: Encodes/Decodes as you type.
• Zero Tracking: No data leaves your machine.

Use Cases:

1. Debugging JWTs: Quickly see what's inside a token.
2. Data URLs: Convert small images to Base64 strings for CSS/HTML.
3. Basic Auth: Generate header strings securely.

Stop taking risks with your data. Use a tool that respects your privacy.
