Base64 is a group of binary-to-text encoding schemes that represent binary data in an ASCII string format. It's commonly used for transmitting data over media designed to handle text.
URL-safe Base64 replaces '+' with '-', '/' with '_', and removes padding '='. This makes the output safe to use in URLs and filenames.

Everything you need to know about Base64 encoding
Base64 encoding converts binary data into a text format using 64 different ASCII characters. It's commonly used to transmit data over channels that only support text content.
Base64 is used for embedding images in HTML/CSS, sending binary data in JSON, storing complex data in databases, and creating data URIs.
URL-safe Base64 replaces '+' with '-', '/' with '_', and removes padding '=', making the output safe to use in URLs, filenames, and query parameters.
No, Base64 is not encryption. It's an encoding scheme that makes binary data safe for text transmission. Anyone can decode Base64 back to its original form.
