Base64 encoding is a way to convert binary data into ASCII text so it can be easily transmitted over networks or stored in a text file. Base64 is commonly used for encoding images, audio and video files, and other types of data in email attachments and other types of messages.
Yes, Base64 encoding is reversible. The process of encoding the data into a Base64 format can be reversed, or decoded, using a special tool or algorithm, to obtain the original data. The Base64 decoder takes the encoded data and converts it back into the original format, such as an image or a document. This is why Base64 encoding is often used for data that needs to be transmitted or stored in a compact format, yet still needs to be able to be accessed and used in its original form.
