Decode an image stored as Base64 and preview its pixels before downloading the recovered file.
Your converted image will appear here in real-time.
Use this decoder for image data embedded in an API response, test fixture, or data URL. The browser reconstructs the image from the encoded bytes. You can inspect the result without uploading the string to an image-decoding server.
Copy a data:image/png;base64,... value from a test response and paste it into the tool. Check that the preview is the expected asset before downloading it.
The encoded bytes must describe an image format the browser can display. Decoding does not upscale, repair, or convert a damaged image.
Paste the Base64 image data into the input area. Check the decoded image preview and detected information. Download the image when its appearance matches your expected source.
