Base64 to Image
Decode a Base64 string or Data URI into an image and download it.
What the Base64 to Image tool does
Base64 is a way of writing binary data, such as an image, using only plain text characters. Developers often embed images directly inside HTML, CSS, JSON, or email templates as a Base64 string so the picture travels with the code instead of living in a separate file. The problem is that a wall of Base64 text is impossible to read with the naked eye, so you cannot tell whether the string is valid or what picture it actually represents.
This tool reverses that process. Paste in a raw Base64 string or a full Data URI (the kind that begins with "data:image/png;base64,") and it decodes the text back into a real, viewable image that you can preview and download. It works with the common web formats including PNG, JPG, GIF, WebP, and SVG, automatically sniffing the format from the data so you do not have to specify it.
How to decode a Base64 string
Paste your Base64 text into the input box, or use the "Paste from clipboard" button to pull whatever you last copied. If you just want to see it in action, click "Use sample" to load a small example string. You can include the "data:" prefix or leave it off; both work.
Press "Decode to Image" and the tool renders the result in the preview panel, with a badge showing the detected format. If the picture looks correct, click "Download Image" to save it to your device with the right file extension. If the string is malformed or truncated, you will see a clear error message instead of a broken image.
Tips and privacy notes
For the cleanest results, copy the entire Data URI including the prefix, because that tells the tool exactly which format to use. If you only have the raw Base64 portion, the tool still tries to identify the format by inspecting the first few decoded bytes, which usually works for PNG, JPG, GIF, and WebP.
All decoding happens locally inside your web browser using built-in JavaScript. Your Base64 string is never uploaded to a server, so you can safely decode sensitive or private images. Nothing is stored after you close or refresh the page.
