About Base64 to Image Converter

Base64 encoded images appear as long strings of characters in HTML source, CSS files, API responses, and JSON payloads. This tool decodes any Base64 image string back into a viewable and downloadable image file.

Paste either a complete data URI (data:image/png;base64,...) or a raw Base64 string. The tool automatically detects the format and renders the image preview. The decoded image can be downloaded in its original format.

How to Use Base64 to Image Converter

1. Paste your Base64 encoded image string into the input field.
2. Include the full data URI prefix (data:image/png;base64,...) or just the raw Base64 string.
3. The decoded image is previewed instantly.
4. Download the image file.

Common Use Cases

• Extracting inlined images: Extract images embedded as Base64 data URIs in HTML or CSS files to save them as separate image files.
• API response inspection: Preview images returned as Base64 strings in API responses to verify the content.
• Debugging image data: Decode Base64 image data from logs, database records, or JSON payloads to inspect what image was stored.
• Email image extraction: Extract and save images that are embedded as Base64 data URIs in HTML email source.

Frequently Asked Questions

Do I need to include the data URI prefix?

The full data URI format (data:image/png;base64,...) is preferred as it includes the image format information. If you paste just the raw Base64 string without the prefix, the tool will attempt to detect the image format automatically.

What image formats are supported?

Any image format that can be Base64 encoded is supported for decoding: PNG, JPG, WebP, GIF, SVG, ICO, and more. The format is determined from the data URI MIME type.

Is there a size limit?

Very large Base64 strings (representing images over 10-20MB) may be slow to process in the browser. For typical web use cases (images under a few MB), processing is instant.
