Frequently Asked Questions
What is Base64 Encoding?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It is widely used to embed images, credentials, or file attachments directly into HTML, CSS, JSON, or XML documents.
How does local processing work?
We leverage Javascript's native `FileReader`, `TextEncoder`, and binary APIs (`atob` & `btoa`) directly in your web browser. This means your text and files stay on your machine, eliminating data leakage concerns.
