Base64转图片转换器

将Base64字符串或数据URL解码为可下载的图片。

如何使用本工具

1
Paste your Base64 payload or full data URL (data:image/...) into the text box. Leading and trailing whitespace in a raw Base64 string is stripped automatically.
2
The decoded image appears as a live preview the moment the browser can render it; if the data cannot be decoded, an 'Invalid Base64 image data' message is shown instead.
3
Click the Download button to save the image to your device as image.png.

如果你接手了一个内嵌数据URL的CSS文件或HTML页面，本工具可以提取出图片，让你能将其保存为文件。粘贴完整的数据URL（data:image/...）或仅粘贴Base64负载：两种我们都能处理。

Recovering an icon or logo that a previous developer hard-coded as a data URL inside a CSS or HTML file, so you can save it back to a real .png file.
Inspecting a Base64 image string returned by an API or stored in a JSON payload to confirm it actually decodes to the picture you expect.
Pulling an embedded image out of an SVG or email template where assets were inlined as data URLs to reduce HTTP requests.
Quickly verifying that a Base64 string copied from logs, a database column, or a clipboard snippet is a valid, renderable image.
Extracting a screenshot or avatar that a tool exported as a data URL when you need the binary file instead of the text blob.
Teaching or demonstrating how data URLs work by pasting an encoded string and watching it render live in the preview.

它接受仅有Base64字符串吗？▼

接受。如果你粘贴的是不带数据URL前缀的原始Base64，我们会假定为image/png。对于其他类型，请粘贴完整的数据URL。
