よくある質問
What is a Base64 to Image converter?
This tool decodes a Base64 encoded string and converts it back into a viewable image file. It is useful for developers or designers working with embedded images in HTML or CSS.
How do I use this calculator?
Simply paste your Base64 string into the provided input text area. The tool will automatically detect the format and display the decoded image. You can then choose to download the image.
Do I need to remove the data:image/png;base64, prefix?
No, you do not. The tool automatically handles Base64 strings with or without the Data URI scheme prefix (e.g., data:image/jpeg;base64,).
What image formats are supported?
This tool supports common formats decoded from Base64, including PNG, JPEG, GIF, BMP, WEBP, and ICO.
Why is my Base64 string so long?
Base64 encoding increases the size of binary data by approximately 33%. Images contain a lot of binary data, so the resulting string is naturally long.
Is the conversion process secure?
Yes, the conversion is performed locally within your browser using JavaScript. Your data is not uploaded to any external server.
