Base64 Converter (Encode/Decode)
The Base64 format is widely used by developers to securely transmit binary data, API keys, and payloads across the web. Paste your text below to encode or decode it in real-time.
Real-Time Encoding and Decoding
No need to click any buttons. As soon as you type or paste your string in the top field, the tool instantly converts and displays the result in the bottom panel.
Guaranteed Security
Many Base64 strings contain database credentials and sensitive tokens. This tool is built to run 100% in your browser, ensuring that nothing is ever saved or sent to servers.
How to use the converter
To encode, paste your normal text in the top field and watch the Base64 appear below. To decode, paste the Base64 and read the original text back. Conversion works both ways in real time, with no button to press — just copy the result when you are done.
Frequently asked questions
What is Base64?
Base64 is an encoding method that transforms binary data into an ASCII character sequence, making it safe for transmission over systems that only support plain text (like emails or JSON payloads).
Is Base64 encryption?
No. Base64 is only an encoding format. It does not use passwords or protection algorithms. Never use Base64 to hide confidential information without encrypting it first.
