Encode text to Base64 or decode Base64 to readable text online. This free Base64 converter supports Unicode, works directly in your browser, and lets you copy results without installing software.
Need to encode text to Base64 or decode Base64 to text? The free HoxTools Base64 Encoder and Decoder makes both tasks simple. Enter your text and select Encode to Base64, or paste a Base64 string and select Decode Base64 to convert it back into readable text.
This online Base64 converter is useful for developers, programmers, students, API testers and anyone working with text-based data. It supports Unicode text and processes encoding and decoding in your browser.
Here is a simple text-to-Base64 example. The text Hello World converts to the following Base64 string:
Original text
Hello World
Base64 encoded result
SGVsbG8gV29ybGQ=
To test this example, enter Hello World
in the input box above and click
Encode to Base64. To reverse the
conversion, enter SGVsbG8gV29ybGQ= and
click Decode Base64.
Base64 is a method of representing binary data using 64 basic characters from the Base64 alphabet. It is commonly used when applications need to represent binary information in a text-based format.
Base64 is an encoding format, not a form of encryption. It does not hide information from someone who can access the encoded value.
The decoder accepts standard Base64 input, including valid input without optional trailing padding. The decoded content must be valid UTF-8 text. Arbitrary binary files are not displayed as readable text by this text converter.
Base64 encoding is frequently encountered in web development and software engineering. Common examples include:
Base64 encoding and URL encoding are different techniques. Base64 represents binary data using its own character set. URL encoding represents characters in a format suitable for use in URLs and commonly converts spaces and reserved characters into percent escapes.
Use the appropriate converter for your task: URL Encoder and Decoder for URL-related encoding, or this page for standard Base64 text encoding and decoding.
Yes. This tool uses UTF-8 encoding and decoding, so it can handle Unicode text such as accented letters and characters from many languages. The decoded data must represent valid UTF-8 text to display correctly.
No. Base64 is not encryption and does not provide password protection or confidentiality. Anyone with the encoded string can decode it. Never use Base64 alone to protect passwords, private keys, access tokens or confidential information.
The encoding and decoding functions on this page run locally in your browser using JavaScript. The tool code does not send the text you enter to a HoxTools processing endpoint. Avoid entering sensitive information into any online service unless you have reviewed its privacy practices.
Base64 is an encoding method that represents binary data using a set of ASCII characters. It is commonly used in APIs, web applications, email systems and data transfer.
Base64 is encoding, not encryption. Anyone who has the encoded data can decode it, so Base64 should not be used to protect passwords or confidential information.
The Base64 encoding and decoding functions on this page run in your browser. The tool's JavaScript does not send your entered text to a HoxTools processing endpoint.
Yes. This Base64 encoder supports Unicode text, including characters from different languages, by converting text to UTF-8 bytes before encoding.
Yes. You can use this free online Base64 decoder in a modern browser with JavaScript enabled. No separate Base64 application is required.
No. Base64 and URL encoding serve different purposes. Use Base64 for standard Base64 data and a URL encoder when preparing characters for use in URLs.
