🔐 Base64

Used for encoding binary data in APIs, email attachments, and data URIs.

Example: btoa("Hello")"SGVsbG8="

🌐 URL Encoding

Spaces become %20, special characters become %XX format.

Example: "Hello World""Hello%20World"

{ } JSON

Lightweight data format used by most modern APIs.

Example: {"name": "Tyzo"}

🎨 Color Codes

HEX (#3b82f6) and RGB (rgb(59,130,246)) represent the same colors.

Frequently Asked Questions

Is Base64 encryption secure?

No. Base64 is encoding, not encryption. Anyone can decode it instantly. Never use Base64 to protect passwords or sensitive data.

What's the difference between encodeURI and encodeURIComponent?

encodeURI() preserves URL structure (:// ? & =). encodeURIComponent() encodes everything, including special characters.

Does JSON support comments?

No. JSON does not support comments. Use a separate documentation file or switch to JSON5 for development.

Yes! All tools on Tyzo are completely free. No sign-up, no credit card, no hidden fees. Forever.
