Base64 to Image Converter

Decode Base64 Strings to Image Files

In modern web development, storing images as Base64 strings (Data URIs) is common for databases and JSON payloads. However, visualizing this data requires decoding. This Base64 to Image Decoder interprets the ASCII character string, reconstructs the binary image data, and renders it immediately in your browser. Because this tool runs entirely via client-side JavaScript, your sensitive image data is never uploaded to an external server, ensuring maximum privacy.

Why Use a Base64 Decoder?

While Base64 is excellent for text transport protocols like email or JSON, it is not human-readable. You need this tool to:

• Debug APIs: Verify image data received from REST or GraphQL endpoints.
• Recover Assets: Extract usable image files from database dumps or logs.
• Convert Formats: Decode a string and save it as a different file type (e.g., convert a Base64 WEBP string to a PNG file).

Frequently Asked Questions

How to convert Base64 to image?

Simply paste your encoded string into the input field above. The tool handles the rest—decoding the characters into binary data and generating a visual preview. You can then download the result.

How to decode a Base64 image?

Decoding is the reverse of encoding. Our tool translates the 64-character ASCII alphabet back into the original binary byte stream, reconstructing the file headers and pixel data to display the image.

How to check if a Base64 string is an image?

Look for the Data URI scheme header: data:image/png;base64,. If you are unsure, paste the string into our tool and click "Validate Base64" to check integrity without fully decoding it.

What is the Base64 image format?

It is not an image file format itself, but a text encoding scheme that allows binary image data to be represented in ASCII string format, often used to embed images directly into HTML or CSS.

How to convert Base64 image to PNG?

Regardless of the original format encoded in the string (e.g., GIF or BMP), our tool allows you to save the decoded output specifically as a PNG file by clicking the "Download PNG" button.
