Base64 to Image Converter
Decode Base64 strings back into actual image files instantly.
About the Base64 to Image Converter
This Base64 to Image Converter is a simple yet powerful utility designed for developers and web designers. Base64 is a method of encoding binary data (like images) into text characters. This is often used to embed small icons directly into CSS files, HTML code, or database fields to reduce the number of server requests.
However, once an image is encoded into this long string of random-looking characters, it is impossible to see what it looks like. That is where this tool comes in. You can paste any valid Data URI or raw Base64 string into the box, and we will instantly decode it and display the original image. You can then download the file back to your computer as a PNG, JPG, GIF, or WEBP.
We built this tool with your privacy in mind. All the decoding happens right here in your web browser using JavaScript. The text you paste and the images you view are never sent to our servers, so you can safely use this for sensitive project assets or internal database strings.
How to Use the Tool
- Copy your Base64 string from your code editor, database, or email.
- Paste the string into the large input box on the left.
- The tool will automatically detect the format and generate a preview on the right.
- Review the file details, such as dimensions and file size.
- Click "Download Image" to save the decoded file to your device.
Frequently Asked Questions
What is Base64?
Base64 is an encoding scheme that represents binary data in an ASCII string format. It is commonly used to transmit data over media that are designed to deal with text, such as embedding images directly into HTML or CSS files to speed up page loading.
What image formats are supported?
This tool supports all standard web image formats, including PNG, JPEG (JPG), GIF, WEBP, BMP, and SVG. The tool automatically detects the format from the Base64 header (e.g., data:image/png;base64,).
Why use Base64 instead of an image file?
Using Base64 allows you to include image data directly inside a document (like an HTML page) without needing to fetch an external file. This reduces the number of HTTP requests a browser has to make, which can slightly improve load times for very small icons or placeholders.
Is my data sent to a server?
No. This tool is completely client-side. When you paste your string, your web browser performs the conversion locally. Nothing is ever uploaded, stored, or shared, ensuring your data remains private.
My image isn't showing. Why?
Ensure you have copied the entire string. Base64 strings are very long, and missing even one character can corrupt the data. Also, make sure the string contains the correct header (e.g., data:image/jpeg;base64,). If the header is missing, our tool tries to guess, but it works best with the full Data URI.
