Question 1

What is Base64 encoding?

Accepted Answer

Base64 is a binary-to-text encoding scheme that represents binary data using only 64 printable ASCII characters (A-Z, a-z, 0-9, +, /). It is commonly used to encode binary data such as images, files, and credentials for safe transmission over text-based protocols like HTTP and email.

Question 2

How do I encode text to Base64 online?

Accepted Answer

Paste your text into the input field and click the 'Encode' button. The tool instantly converts your text to its Base64 representation. You can then copy the encoded string to use in your application, API, or email headers.

Question 3

How do I decode a Base64 string?

Accepted Answer

Paste the Base64 string into the input field and click 'Decode'. The tool will convert it back to readable text or binary data. If the Base64 string represents a file or image, you can download the decoded result.

Question 4

Is Base64 the same as encryption?

Accepted Answer

No. Base64 is an encoding scheme, not encryption. It transforms data into a different representation but does not protect it with a secret key. Anyone can decode a Base64 string without a password. For security, use actual encryption methods like AES after encoding.

Question 5

Does this Base64 tool send my data to a server?

Accepted Answer

No. All Base64 encoding and decoding happens entirely in your browser using JavaScript. Your data is never sent to any server, making this tool completely private and safe to use with sensitive content.
