What is Base64 to Image Conversion?
Need to view or save a Base64-encoded image? This tool converts Base64 Data URIs and raw Base64 strings back into viewable images. Perfect for debugging API responses, extracting embedded images, or recovering image data from logs.
According to MDN Web Docs, Base64 is commonly used to embed images directly in HTML, CSS, and APIs. This decoder reverses that process, letting you view and download the original image file.
Everything happens in your browser — your Base64 data and decoded images never leave your computer. Supports all major image formats including PNG, JPG, GIF, WebP, and SVG.
What Makes This Tool Different
Paste or Upload
Paste Base64 strings directly or upload .txt/.b64 files containing Base64 data. Flexible input methods for any workflow.
Auto Format Detection
Automatically detects image format from Base64 data. Works with Data URIs and raw Base64 strings.
Live Preview
See the decoded image instantly with dimensions and format info. Verify the image before downloading.
Smart Error Handling
Clear error messages for invalid Base64, corrupted data, or unsupported formats. Helps you fix issues quickly.
One-Click Download
Download the decoded image in its original format with proper file extension. No manual conversion needed.
Privacy First
All decoding happens locally in your browser. Sensitive images and Base64 data never touch our servers.
How It Works
Paste or Upload Base64
Paste your Base64 string into the editor, or upload a .txt/.b64 file. The tool accepts both Data URIs and raw Base64.
Auto Convert
As you type, the tool automatically decodes your Base64 and displays the image. No buttons to click.
View or Download
Preview the image with full details, then download it in the correct format with one click.
When You'd Actually Use This
Debug API Responses
APIs often return images as Base64. Paste the response here to quickly view and verify the image data without writing code.
Extract Embedded Images
HTML emails and documents often contain embedded Base64 images. Extract and save them as proper image files.
Recover from Logs
Found Base64 image data in logs or error reports? Convert it back to an image to understand what was being processed.
Verify Data URIs
Check if a Data URI is valid and see what image it contains before using it in your project.
Common Questions
What's the difference between a Data URI and raw Base64?
A Data URI looks like "data:image/png;base64,iVBORw0..." and includes the format. Raw Base64 is just the encoded data. This tool handles both automatically.
Is my data stored or uploaded?
No. All decoding happens in your browser using JavaScript atob() and the Canvas API. Your Base64 data and images never leave your computer.
What image formats are supported?
PNG, JPG/JPEG, GIF, WebP, BMP, and SVG. The tool auto-detects the format from the Base64 data or Data URI prefix.
Why does my Base64 fail to convert?
Common issues: truncated data, missing padding (=), invalid characters, or the data isn't actually an image. The tool shows specific error messages to help you fix it.
Can I convert images to Base64 too?
Yes! Use our Image to Base64 tool to convert images the other way. Perfect for embedding images in code.
Is there a size limit?
Large Base64 strings (10MB+) may cause browser performance issues. For very large images, command-line tools are more suitable.
