What is the Base64 to Image Converter?
Converting Base64 strings back to images reverses the encoding process. The browser decodes the Base64 characters into raw bytes, interprets them as image data based on the MIME type in the Data URI prefix, and renders the result using its native image decoder. This is useful for previewing embedded images from APIs, debugging Data URIs in CSS/HTML, and extracting image assets from Base64-encoded responses without writing code.
How to use the Base64 to Image Converter?
- Paste a Base64-encoded image string into the input area (with or without the data:image/... prefix).
- Click 'Render Image' to decode and display the image preview.
- The tool auto-detects the image format (PNG, JPEG, WebP, SVG, GIF).
- Image dimensions are displayed below the preview.
- Click 'Download' to save the decoded image file locally.
Frequently Asked Questions
What Base64 image formats are supported?
This converter supports any image format that browsers can render: PNG, JPEG, WebP, SVG, GIF, and BMP. The format is detected from the Data URI prefix or defaults to PNG if no prefix is provided.
Do I need the data: prefix?
No. If you paste raw Base64 without the data:image/type;base64, prefix, the tool assumes PNG format and adds the prefix automatically. For best results, include the full Data URI.
Why does my image not render?
Common causes: the Base64 string is truncated or corrupted, contains invalid characters, or the original data isn't actually an image. Check that the string is complete and contains only valid Base64 characters (A-Z, a-z, 0-9, +, /, =).
Is my image data safe?
Yes. Rendering uses the browser's native image decoder. No data is sent to any server.
