Encode and decode Base64.
Input
Output
Output appears here as you type.
What this does
Handles multi-byte UTF-8 correctly in both directions, so emoji and non-Latin scripts round-trip exactly.
Limits
- Text only. For files, use the file tools.
Is this private?
Yes, and you can check rather than take our word for it. Open your browser's network tab and run the tool: your file never appears in it, because there is no server to send it to. The whole site is static files.
