Base64 to Image

Decode Base64 image data from HTML, CSS, JSON, API responses, email templates, and data URLs. Paste the encoded value, preview the result, and download the original image bytes as a file.

Accepted Base64 image input

You can paste a complete data:image/...;base64,... URL or raw Base64 text. Whitespace is ignored, and URL-safe Base64 characters are accepted. Auto detection recognizes common PNG, JPG, GIF, WebP, and SVG signatures; you can override the image type when the source does not include reliable MIME information.

How to decode Base64 to an image

1. Paste the Base64 value and leave image type on Auto detect when possible.
2. Check the preview, detected format, and decoded file size.
3. Choose a file name and download the image.

Selecting a different image type changes the MIME label and file extension; it does not convert the underlying pixels. Use Image Converter when you need an actual PNG, JPG, or WebP conversion. Decoding stays in the browser.
