What is a Base64 to Image Converter?
This tool decodes a Base64-encoded string back into a viewable and downloadable image. Paste any valid Base64 Data URI (e.g., data:image/png;base64,...) and instantly preview the image, then download it in its original format. All decoding happens locally — no server required.
Common Use Cases
- Decode Base64 image strings returned by APIs (e.g., AI image generation APIs)
- Extract and save images embedded in HTML or CSS source code
- Debug Base64-encoded image fields in JSON API responses
- Recover images stored as Base64 in databases
- Preview Data URIs copied from browser DevTools
Supported Data URI Formats
| Format | Data URI Prefix |
|---|---|
| PNG | data:image/png;base64, |
| JPEG | data:image/jpeg;base64, |
| WebP | data:image/webp;base64, |
| GIF | data:image/gif;base64, |
| SVG | data:image/svg+xml;base64, |
Frequently Asked Questions
1. Do I need to include "data:image/..." prefix?
Yes. The tool expects a full Data URI including the MIME type prefix (e.g., data:image/png;base64,...). Bare Base64 strings without a prefix may not decode correctly.
2. What if my string is just raw Base64 without a prefix?
You can manually prepend data:image/png;base64, (or the appropriate MIME type) to the raw string before pasting.
3. Is my data safe?
Yes. Decoding happens entirely in your browser. Your Base64 string is never sent to any server.
