Data URI Decoder
Decode a data: URI, inspect its media type and encoding, and extract text content when possible.
Supports both percent-encoded and Base64 data URIs.
| Metric | Value |
|---|
Privacy: decoding runs locally in your browser. No input data is stored or transmitted.
How it works
Paste a full data: URI. The tool splits the metadata and payload, decodes the data, and shows text output when the content is valid UTF-8.
Examples
- data:text/plain;charset=utf-8,Hello → plain text output
- data:text/plain;base64,SGVsbG8= → Base64-decoded text output
- Binary data → metadata still shown even if text display is not possible
