Base64 to Image

Decode Base64 strings and image data URLs into PNG, JPG or WebP files in your browser. Preview your reconstructed image and download it right here for free now.

100% private — runs in your browser, nothing is uploaded

Decoding runs only in your browser. Your Base64 data is never uploaded to a server.

What is a Base64 to image converter?

A Base64 to image converter turns encoded text back into an image file. Base64 is often used in data URLs, JSON payloads, HTML and API responses. This tool accepts a complete image data URL or raw Base64 text, reconstructs the image in your browser and lets you download it as PNG, JPG or WebP.

Paste the text into the input. If it begins with a data:image prefix, the converter reads the image type automatically. For raw Base64, choose the image type that the original file used. The decoded preview helps confirm that the text represents a valid image before you save the new file.

How to decode Base64

  • Paste a full data URL or raw Base64 image string.
  • Select PNG, JPG or WebP only when the data has no prefix.
  • Choose Decode image to reconstruct and preview it.
  • Download the image in its detected or selected format.

A full data URL contains the MIME type and the Base64 payload. Raw Base64 contains just the payload, so the converter needs you to identify whether it represents PNG, JPG or WebP. Pasting a different type can prevent the preview from loading.

Why use local decoding?

The browser converts the text to bytes and opens it as an image on your device. Nothing is sent to a server, which is useful when the content includes private screenshots, documents or API data. Base64 strings can be large, so avoid pasting untrusted content from unknown sources. The tool validates that the result can load as an image before offering a download.

Base64 is convenient for transferring small embedded assets, but image files are usually more efficient for normal storage and web delivery. Once you recover the file, keep the original encoded text only if you still need it for a template, API request or other text-based workflow. This avoids accidental repeated data loss.

Frequently asked questions

Can I paste a full data URL?

Yes. Paste a data URL beginning with data:image/...;base64, and the converter detects the format.

What if I only have raw Base64?

Select the source image type before decoding so the tool can interpret the bytes correctly.

Why does my Base64 text not decode?

It may be incomplete, use a non-image file type or contain invalid characters.

Is Base64 data uploaded?

No. Decoding and validation happen locally in your browser.
