What is a Base64 to Image Converter?

Base64 image data is a text representation of an image file. It looks like a long string of letters and numbers. A base64 to image converter takes that string and turns it back into a real, viewable image.

This tool supports both raw Base64 strings and full data:image format strings like data:image/png;base64,... You can paste either format and the tool will handle it correctly.

It also detects the image type automatically. You will see details like width, height, MIME type, file size, bit depth, and file extension right after decoding. This makes it easy to inspect image data from APIs, HTML source code, or web app responses.

Once decoded, you can preview the image directly and download it in formats like PNG, JPG, WebP, or BMP. This base64 image decoder is built for developers who need a fast and reliable way to verify and export encoded image data without writing a single line of code.

How to Convert Base64 to an Image

Step 1: Paste Your Base64 String Open the tool and paste your Base64 string into the input area. You can paste a raw Base64 string or a full data:image string starting with data:image/png;base64, or similar.

Step 2: Click "Convert" Press the Convert button. A progress bar will show while the tool decodes your input. If anything looks wrong, the tool will show a clear error message.

Step 3: Preview the Decoded Image Your image will appear in the preview area. You will also see key details like file size, dimensions, MIME type, and file extension.

Step 4: Choose a Format and Download Select your preferred output format such as PNG, JPG, WebP, or BMP. Enter a custom filename if needed, then click Download to save your image.

Frequently Asked Questions

What is Base64 image data?

Base64 image data is a way of representing an image as a plain text string. Instead of a separate image file, the entire image is encoded into characters that can be stored or transmitted inside code, emails, or API responses.

What is the difference between raw Base64 and a data:image string?

A raw Base64 string is just the encoded image data on its own. A data:image string includes a prefix like data:image/png;base64, that tells the browser what type of image it is. This base64 to image converter accepts both formats without any extra steps.

Which image formats are supported?

The tool supports PNG, JPG, JPEG, WebP, GIF, SVG, HEIC, and BMP. After decoding, you can also download the image in formats like JPG, PNG, WebP, or BMP depending on your needs.

Why am I seeing an invalid Base64 error?

This usually happens when the pasted string is incomplete, corrupted, or contains extra characters like line breaks or spaces. Make sure you are copying the full Base64 string from your source without any missing parts.

Will the image quality change after decoding?

No. The base64 to image converter simply reverses the encoding process. The decoded image is identical to the original. No quality is lost during decoding unless you choose to export in a format like JPG that uses compression.

Does this tool work on mobile devices?

Yes. The tool runs fully in your browser and works on smartphones and tablets. You can paste your Base64 string on mobile, preview the image, and download it just as easily as on a desktop.
