What Is a Base64 to Image Decoder?

A Base64 to image decoder is a tool that converts a Base64-encoded text string back into a viewable binary image file. Base64 is a character encoding scheme that represents binary data — such as a PNG or JPG image — as a sequence of ASCII characters, making it safe to embed in HTML, CSS, JSON, XML and data URLs.

Our free browser Base64 image decoder reverses this process: paste your encoded string and instantly see the original image, complete with format detection, dimensions and file size — all without sending a single byte to any server.

When Do You Need to Convert Base64 to an Image?

Extracting embedded images from HTML source, CSS files or JSON API responses where images are stored as Base64 data URLs.
Debugging web applications — developers often inspect Base64 strings from <img src="data:image/png;base64,..."> tags to verify image content.
Converting API payloads — many APIs return images as Base64 strings. This tool lets you preview and download them instantly.
Email attachments — inline images in email HTML are frequently Base64-encoded. Decode them to recover the original image file.

How to Decode Base64 to PNG or JPG

Using our convert Base64 to image online tool takes three steps. Here's exactly what to do to decode Base64 to PNG, JPG or any other format:

Step 1 — Copy your Base64 string. This might be a full data URL like data:image/png;base64,iVBORw0KGg... or just the raw encoded text without the prefix. Both work, and line breaks or spaces from copy-pasting are removed automatically.
Step 2 — Paste and decode. Paste the string into the text area above and click Decode to Image. The Base64 image converter detects the format automatically — from the data URL prefix, or from the file signature if there is no prefix.
Step 3 — Download the image file. Click Download Image to save it. The filename is automatically set to the correct extension (e.g. .png, .jpg). This is how to download image from Base64 in seconds.

Frequently Asked Questions

What is a Base64 to image decoder?

A Base64 to image decoder converts a Base64-encoded text string back into a viewable binary image (PNG, JPG, GIF, etc.). Base64 is commonly used to embed images inside HTML, CSS and JSON without needing a separate file. Our online tool reverses this encoding so you can preview and download the original image from a Base64 string.

How do I convert Base64 to image online?

Paste your Base64 string into the text area above and click Decode to Image. The tool handles both full data URLs (starting with data:image/png;base64,) and raw Base64 strings. It instantly displays the decoded image and lets you download it as a PNG, JPG or GIF file.

Can I decode Base64 to PNG or decode Base64 to JPG?

Yes. This browser Base64 image decoder detects the image format from the data URL prefix, and if you paste a raw string with no prefix it reads the file signature to work out whether it is PNG, JPG, GIF, WebP or BMP. The downloaded file is named with the correct extension (e.g. decoded-image.png or decoded-image.jpg).

Is this a free Base64 to image tool?

Yes, completely free. This is a free Base64 to image tool with no registration, no subscription and no usage limits. It also works 100% offline once the page is loaded — no internet connection required after first visit.

Is my Base64 data safe?

Absolutely. This tool is entirely client-side. Your Base64 string never leaves your device — all decoding happens in your browser using JavaScript with no network requests whatsoever. This makes it the safest option compared to server-side online tools.

What does a Base64 image string look like?

A Base64 image string usually starts with a data URL like data:image/png;base64, followed by a long sequence of characters (letters, numbers, +, / and =). For example: data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAA.... You can also paste just the encoded part (without the prefix) — the decoder identifies the format and adds it automatically.
