Getting started

How to decode Base64 to an image

Three steps from string to file.

1. Paste

Paste the Base64 string or full data URI into the input.

2. Preview

The tool detects the format and renders a live preview.

3. Download

Save the image with the correct extension.

Input

What the decoder accepts

Multiple Base64 variants work out of the box.

Plain Base64 string

iVBORw0KGgoAAAANSUhEUgAAAAUA...

Raw characters with no prefix.

Data URI

data:image/png;base64,iVBORw0KGgo...

Includes the MIME type prefix — the tool strips it automatically.

URL-safe Base64

iVBORw0KGgoAAAANSUhEUgAAAAUA...

Replace -/_ with +/ is handled automatically where needed.

When it helps

Typical reasons to decode Base64 images

Debug API responses

APIs that return images as Base64 — decode the string to check what the client actually receives.

Inspect data URIs

Pull a data URI out of HTML or CSS, paste it here, and view the embedded image as a file.

Extract from JSON payloads

Some back-ends embed avatars or previews directly in JSON. Decode to confirm or save.

Recover screenshots

Logs sometimes include Base64 screenshots for bug reports. Decode them to view the actual image.

Heads up

Common pitfalls

Including surrounding quotes

Some JSON strings arrive wrapped in quotes. Strip the outer quotes before decoding.

Hidden whitespace or line breaks

Line breaks inside the Base64 string usually decode fine, but leading / trailing whitespace sometimes breaks parsers.

Truncated strings

Copy-pasting from a narrow terminal or email can cut off the end of a Base64 string. Make sure the full payload is included.

Wrong prefix

If the data URI mime type is wrong (e.g. a JPG labeled image/png), the file saves with the wrong extension. Check the preview.
