Frequently Asked Questions

What is Base64 encoding used for?

Base64 encoding converts binary data into ASCII text format, making it safe for transmission over text-based protocols like email, HTTP, and JSON. It's commonly used for embedding images in HTML/CSS and encoding authentication tokens.

Is my data secure during encoding?

Yes, all encoding happens locally in your browser. Your data never leaves your device and is not sent to any servers.

Can I encode files as well as text?

Yes, you can encode both text input and binary files. The tool handles various file types and converts them to Base64 format.

Is there a file size limit?

The limit depends on your browser's memory capacity. For very large files, consider using smaller chunks or a desktop application.
