Base64 to Image Converter
What Is It?
The Base64 to Image Converter takes a Base64-encoded string and renders it as a visible image directly in your browser. It supports raw Base64 strings as well as full Data URI format (e.g., data:image/png;base64,...) and allows you to download the resulting image.
No file uploads, no server processing — everything happens locally.
How to Use
- Paste your Base64 string into the input field. You can include or exclude the
data:image/...;base64,prefix. - Click Preview Image.
- The image renders in the preview area.
- Click Download Image to save the file to your computer.
Supported Image Formats
- PNG
- JPEG / JPG
- GIF
- WEBP
- SVG
- BMP
Example
Paste a string like:
data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUA...
Or just the raw Base64 part:
iVBORw0KGgoAAAANSUhEUgAAAAUA...
Both inputs will render the image correctly.
Benefits
- Auto-detect format — the tool automatically detects the image type from the Base64 signature.
- Full Data URI support — works with and without the
data:prefix. - One-click download — save the image to disk in the correct format.
- File size estimate — see an approximate size before downloading.
- Image dimensions — displays natural width and height.
Common Use Cases
- Previewing Base64-encoded images embedded in API responses or JSON payloads.
- Debugging CSS background images stored as Data URIs.
- Converting email-embedded images from Base64 back to file format.
- Inspecting Base64 image values in web scraping results.
- Recovering images from database blobs stored as Base64 strings.
Frequently Asked Questions
What is a Base64 image string?
A Base64 image string is a text representation of binary image data. Images are binary files, but Base64 encoding converts them into a safe ASCII string that can be embedded in JSON, HTML, or CSS without needing a separate file request.
Why does my image show garbled output?
This typically happens if the Base64 string is truncated or corrupted. Ensure you’ve copied the complete Base64 value without any line breaks unless the original format included them as padding.
Is there a size limit?
The tool works for images up to several megabytes. Larger Base64 strings (50MB+) may cause performance issues depending on your browser and available memory.
Can I convert the image back to Base64?
Yes — use our Image to Base64 tool to go in the reverse direction.
