Frequently Asked Questions
Everything you need to know about the Base64 Encoder/Decoder.
What is Base64?
Base64 is a way of writing any data, including images and files, using only 64 safe text characters: letters, numbers, + and /. It lets binary data travel through systems that only handle text, such as email and JSON.
Is Base64 encryption?
No. Base64 is an encoding, not encryption. Anyone can decode it instantly, so never use it to hide passwords or secrets.
Why is the encoded output larger than my file?
Base64 uses four characters for every three bytes of data, so encoded output is about 33 percent larger than the original. That is why it is best for small files and icons.
What is a data URI?
A data URI starts with data: followed by the file type and the Base64 content. You can use it directly as an image source in HTML or as a background in CSS, without a separate file.
