Base64 Encoder/Decoder
Easily convert text, images, and files to Base64 format.
What is a Base64 Converter?
Base64 encoding is a method of converting binary data into text (ASCII characters). It is commonly used for email transmission and data URI schemes (such as embedding images directly into HTML).
With this tool, you can easily encode text or files into Base64 or decode them back to their original form. All processing is done entirely within your browser without passing through a server, so even sensitive files or data can be converted safely.
FAQ
Does Base64 encoding encrypt data?
No. Base64 is an “encoding” method, not “encryption.” Anyone can decode it to view the original content, so it should not be used to protect passwords or personal information.
What are the benefits of converting images to Base64?
Converting image files into Base64 strings allows them to be embedded directly into HTML or CSS files. This can reduce separate image requests during page loading and help optimize performance. However, since the encoded string is about 33% larger than the original file, it is most efficient for very small icons or images.
