Frequently Asked Questions
What is a Data URI?▼
A Data URI allows you to embed files inline within web pages using the syntax `data:[<mediatype>][;base64],<data>`.
Is my Base64 string sent to a server?▼
No. Decoding is performed locally using the browser's native JavaScript `atob` and `Uint8Array` primitives.
