What is Base64 encoding?

Base64 is a method of encoding binary data into ASCII characters. It uses 64 different characters (A-Z, a-z, 0-9, +, and /) to represent data, with = used for padding. This encoding makes binary data safe to transmit over text-based systems.

When should I use Base64 encoding?

Use Base64 when you need to represent binary data in a text format, such as embedding images in HTML/CSS, sending file attachments in email, or including binary data in JSON/XML documents. It's not for encryption or compression.

Is Base64 secure for sensitive data?

No, Base64 is not encryption. It's simply an encoding scheme that can be easily reversed. Anyone who can see the Base64 data can decode it. For sensitive data, use proper encryption like AES before encoding.

Does Base64 increase file size?

Yes, Base64-encoded data is typically about 33% larger than the original binary data. This is because every 3 bytes of binary data becomes 4 bytes of Base64 text.

About Base64

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It’s commonly used when there’s a need to encode binary data that needs to be stored and transferred over media designed to deal with text.

Common uses include:

Encoding images for embedding in HTML or CSS
Sending binary data over text-based protocols like email
Storing complex data in JSON or XML
Basic obfuscation of sensitive data (not secure encryption)

🔐 Base64 Encode Decode Tool – Online Text to Base64 Converter

Base64 is a commonly used encoding scheme that converts binary data into ASCII characters. It’s widely used in web development, data transmission, APIs, and email encoding. The Base64 Encode Decode Tool from EarnApKi.com allows you to convert your text into Base64 format or decode it back—quickly, securely, and without installing anything!

⚙️ What Is Base64 Encode Decode Tool?

Base64 is an encoding technique that transforms binary or text data into a string of readable ASCII characters. It’s not encryption—just a way to ensure that binary data can safely travel across systems that only handle text.

Example:

Text: Hello, world!
Base64: SGVsbG8sIHdvcmxkIQ==

This makes Base64 ideal for embedding images, files, or credentials inside code or HTML.

⚠️ Is Base64 Secure?

No—Base64 is not encryption. It simply encodes data to ensure it passes safely over systems like email or web forms. Do not use Base64 to store passwords or sensitive data.

For encryption, use secure methods like AES, RSA, or SHA.
