Frequently Asked Questions
What is the difference between a data URL and raw Base64? ▼
A data URL includes a MIME type prefix: data:image/png;base64,... A raw Base64 string is just the encoded data without that prefix. This tool handles both automatically.
Is my data sent to a server? ▼
No. Decoding happens entirely in your browser using the built-in atob() function.
