Base64 to Image Converter

Base64 is how images travel as text, but text is not a picture, and sooner or later you need the picture back. A Base64 string copied from code, an API response, or a data file can be decoded in this tool and shown as the image it represents, ready to download as a real file again.

This is the reverse direction of the existing image-to-base64 tool, which only encodes images into text and offers no way to paste text back. That existing tool was checked before building this one: it uploads an image and outputs Base64, with no decode input at all, so this decoder is a genuinely separate tool rather than a duplicate.

Quick Answer: Paste a Base64 string or data URI and get the image back, previewed and downloadable.

How to Use the Base64 to Image Converter

Enter or upload your input in the box above.
Check the settings match what you need before you run it.
Press the main button to run the conversion.
Review the result shown below the controls.
Copy the result or download it, then use it wherever you need it.

Key Features

Runs entirely in your browser, so nothing is uploaded to a server.
No account, sign-up, or installation is needed to use it.
Works on desktop and mobile browsers alike.
Decodes raw Base64 strings and full data URIs alike.
Detects PNG, JPEG, and GIF from the decoded bytes.
Shows a preview and offers the image as a download.

Best Practices and Tips

Double-check your input before running the tool, since the output is only as good as what you enter.
Keep a copy of the original input until you have confirmed the result works.
Paste the full string; one missing character breaks the image.
If the string has a data URI prefix, paste it whole; the tool strips it.
Download the image rather than screenshotting the preview for full quality.

Common Mistakes to Avoid

Running the tool on incomplete input and trusting the first result without a glance.
Forgetting to save or copy the output before closing the tab.
Pasting a Base64 string with line breaks copied from code without checking.
Assuming a decoded image is safe; scan files from unknown sources first.

Frequently Asked Questions

What does the Base64 to Image Converter do?

The Base64 to Image Converter takes a Base64 string or a full data URI and turns it into the decoded image, previewed and downloadable, right in your browser. You do not need to install anything or create an account, and the result is ready in seconds. It is built for everyday jobs where you want a quick, reliable answer without opening a heavy desktop program or uploading your files anywhere.

Is my input private when I use this tool?

Yes. Everything you type, paste, or upload is processed locally in your own browser tab, so it never travels to a server run by this site. The only exception is a feature that explicitly needs a device, such as a camera or microphone, and even then the media stays on your device. Closing the tab ends the session, and nothing about your input is stored on the site.

What should I do if the result looks wrong?

First, check the input for typos, missing values, or an unsupported format, because most unexpected results come from the input rather than the tool. Try a small, simple example you can verify by hand, then compare it with the tool output. If the simple case works and the real case does not, the difference usually points to the part of the input that needs fixing.

How is this different from the image to Base64 tool?

The existing tool goes one way only: it uploads an image and outputs Base64 text, with no input for pasting text back. This tool goes the other way: it takes Base64 text and returns the image. Together they form a pair, but neither replaces the other.

What image formats work?

PNG, JPEG, and GIF are detected from the decoded bytes and previewed directly. Other formats that browsers can display, such as WebP and SVG text, are passed through with the MIME type from the data URI where one is given.
