Base64 to Image

About This Tool

The Base64 to Image Converter decodes a Base64-encoded Data URI string and renders the image directly in your browser. Paste the full Data URI (including the data:image/png;base64, prefix) or just the raw Base64 string, and the tool will display a preview of the image. You can then download the decoded image as a file. Supported formats include PNG, JPEG, GIF, WebP, SVG, and BMP.

All decoding runs entirely in your browser — no Base64 data is sent to any server. The image is reconstructed locally using the browser's native Data URI support.

How to Use

1. Paste the Base64 Data URI into the input area. It should start with data:image/...;base64, followed by the encoded string.
2. Click Decode to render the image preview.
3. Verify the image looks correct. The image dimensions and MIME type are shown above the preview.
4. Click Download to save the image as a file.

Use Cases

Developers debugging CSS backgrounds with Base64-embedded images decode them to verify the content. Back-end engineers receiving image data as Base64 in API responses decode them for inspection. Front-end developers reviewing HTML or CSS with inline images extract and preview the embedded images. Anyone receiving a Base64 image string and needing to see what it looks like can use this tool without writing code.

FAQ

• What formats are supported? — Any image format that your browser supports: PNG, JPEG, GIF, WebP, SVG, BMP, and ICO.
• Do I need the data: prefix? — No. If you paste raw Base64 without the prefix, the tool assumes PNG format and adds the prefix automatically.
• Why does my image appear broken? — The Base64 string may be truncated or corrupted. Make sure you copied the entire string, including any trailing = padding characters.
• Is my image sent to a server? — No. The entire decode and preview happens in your browser. Your data never leaves your device.
