How it works.
Base64 is a group of binary-to-text encoding schemes that represent binary data in an ASCII string format. This tool handles UTF-8 characters (like emojis 🚀) correctly. All processing happens locally in your browser.
Is Base64 a form of encryption?
No. It is a form of encoding. Anyone can decode it easily. It is used to ensure data remains intact during transit, not to hide it.
Why do URLs have %20 in them?
URLs cannot contain spaces. URL encoding replaces spaces with %20 or + so the browser can read the address correctly.
Can I encode images into Base64?
Yes, you can turn small images into text strings to embed them directly into HTML or CSS files, reducing the number of server requests.
