About Base64 to Image

The Base64 to Image decoder renders a Base64-encoded string or data URL as a viewable image right in your browser. Paste a raw Base64 string or a full data: URI to preview the image and download it as its original format (PNG, JPEG, GIF, SVG, or WebP). Everything is processed locally — no file is uploaded anywhere.

Features

  • ✓Accepts raw Base64 strings and full data: URIs
  • ✓Auto-detects missing data: prefix and adds data:image/png;base64, if needed
  • ✓Renders image preview with transparent checkerboard background
  • ✓Download the decoded image in its original format
  • ✓Shows clear error for invalid Base64 or unsupported formats
  • ✓Built-in example SVG for quick testing
  • ✓100% client-side — no data leaves your browser

Common Use Cases

  • Debugging data URIs embedded in CSS or HTML source code
  • Previewing Base64-encoded images returned by REST APIs
  • Downloading images that are stored as Base64 in JSON files or databases
  • Verifying that an Image to Base64 conversion was successful

Frequently Asked Questions

QCan I paste a raw Base64 string without the data: prefix?

Yes. If the input does not start with data:, the tool automatically prepends data:image/png;base64, before rendering. If the actual image format is different (e.g. JPEG), load it with the full data URI instead.

QWhat image formats are supported?

Any image format your browser can render: PNG, JPEG, GIF, WebP, SVG, BMP, and AVIF. The download uses the MIME type embedded in the data URI to determine the file extension.
