Base64 to Image Converter
Paste a Base64 string or data URL to preview and download it as an image file. Runs entirely in your browser.
How it works
Paste either a full data URL (data:image/png;base64,…) or only the Base64 characters. The browser then tries to decode the text as an image: if it succeeds you get a preview and a download button, and if not you see an error. Nothing is re-encoded, so the saved file is exactly the decoded data.
File name and type
The download is called decoded-image, and your browser normally adds an extension based on the image type in the data URL. Bare Base64 is treated as PNG, so it is saved as a .png even if the bytes are really a JPEG or GIF — paste the full data:image/jpeg;base64,… URL to keep the right type.
Limits
Only image data works: Base64 for a PDF, audio or text file shows the error message. Unlike the file tools, there is no size check on the pasted text, so extremely long strings can slow the tab.
Frequently asked questions
Does this work with a bare Base64 string, not just a full data URL?
Yes — paste either a full data:image/...;base64,... string or just the bare Base64 characters, and it will be treated as a PNG image if no format is specified.
