Base64 Decoder: Decode Strings and Files

alien

The Base64 decoder allows you to decode encoded strings, returning them to their original form. This tool is useful for working with encoded data in web development.

Base64 is used to store images, transmit data in URLs, and encode confidential information. Our decoder helps to easily convert such strings into understandable text or binary files.

The service supports reverse encoding and is convenient for developers, testers, and security specialists.

Frequently Asked Questions (FAQ)

Base64 is a method of encoding binary data into ASCII text. It's used to safely transmit data over text-based protocols like email, embed images in HTML/CSS, and store binary data in text formats like JSON or XML.

No, Base64 is encoding, not encryption. It's designed for data transmission and storage, not security. Anyone can easily decode Base64 data without a key. For security, use proper encryption methods.

Base64 encoding increases file size by approximately 33% because it represents every 3 bytes of original data with 4 ASCII characters. This overhead is the trade-off for text-safe transmission.

You can decode any valid Base64 string. Invalid strings will produce an error. The decoder will attempt to process the data, but the result is only meaningful if the original data was meant to be text or a recognizable format.

Common uses include embedding images in emails, storing binary data in databases, transmitting files via APIs, encoding certificates and keys, and including resources directly in web pages or applications.
