Frequently asked questions
Can I encode files, not just text?+
This tool encodes and decodes plain text; use a file-specific tool for binary files.
Is my text sent to a server?+
No, encoding and decoding happen entirely in your browser.
What happens if I try to decode invalid Base64?+
You'll see a clear error message instead of garbled output.
