Binary Encoding // RFC 4648

The Mechanics of Base64 Encoding & Binary-to-Text Representation

How RFC 4648 translates 8-bit binary octets into a 64-character ASCII alphabet, enabling safe data transmission over legacy text-only network protocols.

📐

6-Bit Radix Translation

Every 3 bytes of binary data (24 bits) are divided into four 6-bit chunks, mapped onto a 64-character alphabet, expanding payload size by ~33%.

🌐

Standard vs URL-Safe Variant

Standard Base64 uses "+" and "/" with "=" padding. URL-safe Base64 replaces them with "-" and "_" to avoid URL parameter and path collisions.

🔤

Full UTF-8 Multilingual Support

Correctly handles multi-byte UTF-8 emoji and international characters using modern Unicode encoding techniques.

Local Sandbox Processing

Encode tokens, API credentials, and confidential documents with 100% certainty that zero bits leave your browser.

Knowledge Base // FAQ

Frequently Asked Questions

Evidence-based insights on mechanics, precision, and privacy.

Why does Base64 increase file size by 33%?
Base64 represents 3 bytes of binary data using 4 ASCII characters. Because each ASCII character carries only 6 bits of information, the encoded output is roughly 133% the size of the original binary.
What is the difference between standard and URL-safe Base64?
Standard Base64 uses "+" and "/" characters, which have special meanings in URL query strings. URL-safe Base64 substitutes "-" and "_" to prevent encoding breakage.
Is Base64 an encryption algorithm?
No. Base64 is purely a public encoding format designed for data transmission over text channels, not cryptographic secrecy. Anyone can decode it instantly.
Can I decode JWT tokens using this tool?
Yes. You can paste the header or payload segment of any JSON Web Token to decode its JSON contents.
