What is Base64?
Base64 is a scheme to encode to base64 or decode base64 strings. It's commonly used for base64 image data, URLs, and tokens in python base64 encode tasks.

- Not encryption; it's reversible encoding.
- Adds about 33% size overhead compared to raw data.
When to use Base64
- Embedding small images in HTML or CSS
- Sending binary data through text-only systems
- Inspecting tokens or payloads during debugging
Base64 FAQs
Why does my Base64 output end with '='?
The '=' characters are padding to make the output length divisible by four. This is normal.
Does this tool send my data to a server?
No. The encoding and decoding happen in your browser.
