功能介紹

The Base64 to Image tool converts Base64 strings into real images you can preview and download. It is ideal when you receive Base64 image data from APIs, logs, or HTML and need to see or save the actual picture.

什麼時候用這個工具?

Use this tool whenever you need to turn a Base64 image string into a viewable file: debugging inline images, extracting pictures from JSON responses, or checking data URIs.

使用步驟

1

Paste your Base64 string

Paste a full data URI (starting with data:image/...) or the raw Base64 string into the input box.

2

Convert to image

Click the convert button to decode the Base64 and render the image directly in your browser.

3

Preview the result

Verify that the decoded image looks correct and matches what you expect from the source data.

4

Download the image

Save the generated image file to use in design tools, documentation, or further processing.

使用範例

Inspecting a data URI from HTML

Paste a long data:image/png;base64,... string from HTML or CSS and instantly see the embedded image.
