How It Works
Encode text to Base64
Convert any text to Base64 encoded format. Base64 encoding represents binary data as ASCII text, making it safe for transmission in URLs, emails, JSON, XML, and other text-based protocols. Essential for developers working with APIs, data URIs, and encoded payloads.
Key Features
- ✓Encode any text to Base64
- ✓UTF-8 text encoding support
- ✓Standard and URL-safe Base64 variants
- ✓Instant encoding with copy button

Frequently Asked Questions
Is Base64 encryption?▼
No. Base64 is encoding, not encryption. It transforms data format but does not protect it. Anyone can decode Base64 — it provides no security.
Why does Base64 make text longer?▼
Base64 represents 3 bytes as 4 characters, resulting in approximately 33% size increase. This overhead is the cost of ensuring safe text transmission.
