The easiest way to work with Base64 strings. Encode text, decode strings, and handle UTF-8 characters without errors.
Base64 is a method of converting arbitrary binary data (like images, files, or text containing special characters) into an ASCII string format. This makes the data safe to transport over protocols that are designed to handle only text, such as Email (SMTP) or HTML/CSS URLs.
👋 Hello World encodes correctly.| Scenario | Action |
|---|---|
| Basic Authentication | Encode `username:password` to send in HTTP Headers. |
| Data URIs | Embed small images directly into HTML/CSS to reduce HTTP requests. |
| Obfuscation | Hide email addresses from simple scraping bots on websites. |
Simple, fast, and error-free.
Standard JavaScript `btoa()` functions fail with special characters. We've implemented a robust wrapper that handles multi-byte characters (like Chinese, Arabic, or Emojis) seamlessly.
Encode any language reliably.
No. Base64 is an encoding scheme, not encryption. It obfuscates data but provides no security. Anyone can decode it easily.
Yes. Base64 encoding typically increases the size of the data by approximately 33% compared to the original binary data.
