About the Base64 Encode / Decode
Base64 turns any text or binary into a plain-text string of letters and digits — handy for embedding data in URLs, JSON, emails or data-URIs. This tool encodes and decodes it, UTF-8 safe, in your browser.
What this tool checks
- Encodes text to Base64 (UTF-8 safe)
- Decodes Base64 back to text
- Runs entirely client-side
Frequently asked questions
Is Base64 encryption?
No — it's encoding, fully reversible by anyone. Never use it to hide secrets.
Why is my decoded text garbled?
The input probably wasn't valid Base64, or was binary (an image) rather than text.
