What is Base64 encoding?

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It is commonly used in email, URLs, and data embedding in web pages.

Why would I need to encode text to Base64?

Common use cases include embedding images in HTML/CSS, encoding data for APIs and webhooks, creating data URIs, and safe transport of binary data over text-based protocols.

Is there a character limit?

There is no hard character limit. The tool can handle large text inputs, but very large inputs may take a moment to process in your browser.

Is the encoding done locally?

Yes, all encoding happens in your browser using the built-in btoa() function. No data is sent to any server.
