Questions

Is Base64 encryption?

No. It is an encoding, readable by anyone who decodes it. Never use it to protect a secret.

Is my text sent to a server?

No. This tool runs entirely in your browser — nothing you type or paste is uploaded, logged or stored anywhere.

Is there a limit on how much text I can use?

There is no fixed limit. Very large documents depend on your device’s memory, but ordinary pages and files are handled instantly.
