About Base64 Encoding
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used in web development, email systems, and data storage.
Common Use Cases:
- • Encoding binary data for transmission over text-based protocols
- • Embedding images in HTML/CSS as data URLs
- • API authentication tokens
- • Email attachments (MIME encoding)
- • Storing binary data in JSON or XML
Copy-friendly output
Grab encoded strings, hashes, or generated tokens without fighting formatting.
No CLI required
When you do not have openssl, jq, or a local script handy, use the web form.
Works everywhere
Same utility on locked-down laptops where you cannot install new packages.
