How It Works
The tool converts Unicode text to bytes, then encodes those bytes as Base64. Decode mode reverses that process.
Example
Hello becomes SGVsbG8= in Base64.
Frequently Asked Questions
Is Base64 encryption?
No. Base64 is encoding, not encryption. Anyone can decode it.
Is text sent to a server?
No. Encoding and decoding run locally in your browser.
Does this send data to a server?
The current draft tools are designed for browser-side utility work. Still avoid pasting secrets unless the project has been fully reviewed for your deployment.
Should I verify output?
Yes. For production work, validate the result in your actual codebase, terminal, CI, or target environment.
