Base64 to Image
Paste a Base64 encoded string and instantly preview the decoded image. Runs entirely in your browser - nothing is sent to any server.
How It Works
Base64 encoding represents binary data (like images) as an ASCII text string. This tool reverses that process - it takes a Base64 encoded string and converts it back into a viewable, downloadable image.
- Paste your Base64 string into the input area. Both raw Base64 and
data:image/...URI formats are accepted. - Click Decode to convert the string into an image.
- Preview the result and click Download to save it to your device.
Supported Formats
The tool auto-detects the image format from the data URI prefix. If you paste raw Base64 without a data URI header, it defaults to PNG. Supported formats include:
- PNG - Portable Network Graphics
- JPEG / JPG - Joint Photographic Experts Group
- GIF - Graphics Interchange Format
- WebP - Modern image format by Google
- SVG - Scalable Vector Graphics
- BMP - Bitmap Image
- ICO - Icon format
Privacy & Security
Your Base64 data never leaves your browser. All decoding is performed client-side using the native atob() function and Blob APIs. No data is uploaded, logged, or stored on any server.
