About Data URI Conversion
Prepare self-contained image payloads for multimodal AI requests, local demos, and inline previews. The tool can read an uploaded image or accept raw Base64 input, then build a ready-to-use Data URI string.
Why generate a Data URI?
Some multimodal and frontend workflows work better with a single self-contained string than with separate image hosting or file uploads. A Data URI also preserves the MIME type in the payload itself.
Key Features
- Supports direct image upload or manual Base64 input.
- Preserves and edits the MIME type used in the final URI.
- Shows a browser preview to verify that the payload renders correctly.
- Runs locally so image data does not need to be uploaded elsewhere.
How to Use
- Upload an image or paste the Base64 content into the input field.
- Confirm or adjust the MIME type.
- Copy the Data URI and use it in your multimodal payload or inline preview.
