Convert Base64 to Image Online
When you receive a Base64-encoded image from an API, find one in a data URI, or need to view image data that is stored as a Base64 string in a database or configuration file, you need a tool to decode it back into a viewable image. This tool accepts a Base64-encoded image string (with or without the data URI prefix) and renders the decoded image directly in your browser. You can preview the image and download it as a file. Supported formats include PNG, JPEG, GIF, WebP, and SVG, detected automatically from the data URI MIME type or the Base64 content. The entire decoding process happens client-side — your Base64 data never leaves your browser.

FAQ
- Do I need to include the data URI prefix?
- No. You can paste just the Base64 string (without the data:image/... prefix) and the tool will detect the image format from the encoded content. Including the full data URI also works.
- Can I download the decoded image?
- Yes. After previewing the image, you can download it as a file in its original format (PNG, JPEG, etc.).
- What if my Base64 string is from a JSON API?
- JSON APIs sometimes return image data as a Base64 field. Copy the value of that field (without the surrounding quotes) and paste it into this tool to view the image.
