Base64 Encode / Decode

Convert plain text to Base64 encoded string or decode Base64 back into readable text with full Unicode / UTF-8 support.

What is Base64 Encoding?

Base64 is a binary-to-text encoding scheme designed to represent binary data in an ASCII string format. By translating 8-bit binary data into a set of 64 printable ASCII characters, Base64 ensures that data remains intact without modification during transfer across legacy network systems, email gateways, or text-oriented protocols.

Frequently Asked Questions (FAQ)

Is Base64 encryption?

No. Base64 is an encoding format, not encryption. It provides zero confidentiality as anyone can decode it instantly without a key.

Are emojis and special characters supported?

Yes! This tool serializes input into UTF-8 byte streams using TextEncoder / TextDecoder before Base64 transformation.
