FAQ
How do I convert a Base64 string to an image?
Paste your Base64 string or full data URI into the tool: the decoded image appears instantly and a button lets you download it in its original format (PNG, JPG, etc.).
What is a data URI?
A data URI is a string that embeds a file's content directly, prefixed for example with data:image/png;base64,. It lets you include an image in HTML or CSS without an external file.
Do I need to include the data:image prefix in the string?
The tool accepts both cases: a full data URI with its data:image/...;base64, prefix, or the plain Base64 string. The format is detected automatically to rebuild the correct image.
