Convert text to Base64 and decode Base64 to text instantly. Perfect for developers, API testing, and data encoding. Supports file uploads and downloads.
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used to encode binary data for transmission over text-based protocols like email and HTTP.
All encoding and decoding happens in your browser. Your data is never sent to our servers, ensuring complete privacy and security.
Base64 encoding is used to convert binary data into text format for safe transmission over text-based protocols. Common uses include embedding images in HTML, API data transmission, and email attachments.
No, Base64 is not encryption - it's just encoding. Anyone can decode Base64 data easily. Don't use it for sensitive information without proper encryption.
Yes, you can upload and encode various file types including text files, images, and binary files. The tool will convert them to Base64 format.
Base64 is encoding (reversible transformation), while encryption is a security measure that requires a key. Base64 is easily reversible, encryption is not without the proper key.
Base64 encoding increases data size by approximately 33% because it uses 4 characters to represent every 3 bytes of original data.
