Frequently Asked Questions (FAQ)
Base64 is an encoding method that converts binary data into ASCII text. It's used to transmit images via email, embed data in URLs, or store binary data in text format.
No, Base64 is only encoding, not encryption. Data encoded in Base64 can be easily decoded by anyone. It offers no security, it only serves format compatibility.
Our tool primarily supports text, but you can encode binary content if you first convert it to hexadecimal format or paste it as text. For complex files, use dedicated tools.
Yes, Base64 preserves all characters including Unicode, emojis, and special symbols. Decoding will restore exactly the original text.
Base64 increases size by about 33% because it converts every 3 bytes into 4 ASCII characters. This overhead is the price for ensuring compatibility with systems that only accept ASCII text.
