How Base64 encoding and decoding works
Base64 is a widely used encoding scheme that converts binary data or standard text into an ASCII string format. This tool uses your browser's native JavaScript functions (btoa() and atob()) to instantly encode your plain text into Base64 format, or decode an existing Base64 string back into readable text. Everything is processed locally without sending data to any server.
Base64 Utility FAQ
Is it safe to encode sensitive tokens or credentials?
Yes. Because this tool is entirely client-side, any API keys, authentication tokens, or sensitive credentials you paste here remain strictly on your device. We have no backend server that logs or stores your inputs.
Is Base64 considered encryption?
No. Base64 is an encoding format, not an encryption method. It is meant to ensure data remains intact during transport across networks, but it does not hide or secure the data. Anyone with a Base64 decoder can easily read the original text.
