Frequently Asked Questions

Can I encode files, not just text?+

Yes, you can upload a file and get its Base64-encoded representation, useful for embedding small files inline, like in CSS or JSON.

Why would I need to encode something as Base64?+

Base64 is commonly used to safely embed binary data, like images, inside text-based formats such as HTML, CSS, JSON, or emails.

Is my data uploaded to a server to encode or decode it?+
