Base64 to Image
Convert Base64 strings or Data URLs back into downloadable images entirely in the browser.

What can you do with the Base64 to Image tool?
Extract images from code
Instantly recover original image files embedded as Data URIs within HTML, CSS, or JavaScript files without needing developer tools.
Inspect JSON payloads
Decode raw Base64 strings sent over APIs or stored in databases to verify visual content or troubleshoot data transmission issues.
Recover lost assets
Convert Data URLs back into standard image files like PNGs or JPEGs when you no longer have access to the original uploaded graphic.
Smart auto-extraction
Paste massive chunks of HTML or CSS directly into the input field; the tool will automatically locate, extract, and decode the first embedded Data URL.
How does this tool work?
The Swelity Base64 to Image tool reverses the encoding process securely inside your browser. Here is the step-by-step flow:

Why convert Base64 back to images?
Base64 encoding is excellent for transport, but terrible for editing. While Base64 allows you to safely transfer binary image data over text-based protocols (like JSON) or embed small graphics into stylesheets, you cannot edit or manipulate a Base64 string directly in design software like Photoshop or Figma.
Decoding restores standard file functionality. By converting a Base64 string back into a standard binary image file (like a .png or .jpeg), you regain the ability to optimize it, crop it, resize it, or share it on platforms that do not support raw text data URIs.
Frequently Asked Questions
What is a Base64 image?
Base64 is a way to encode binary data (like an image) into a string of plain text characters. Decoding it reverses the process, turning the text back into the original visual file.
What is the difference between Raw Base64 and a Data URI?
A Data URI includes a metadata prefix (like data:image/png;base64,) that tells the browser exactly what type of file it is. Raw Base64 is just the raw text payload without any formatting prefix.
Can I decode an entire HTML tag?
Yes! If you paste an entire <img src="data:image/..."> tag, our tool is smart enough to scan the text, extract the embedded Data URI, and decode it automatically.
Why do I have to select a format for Raw Base64?
Because Raw Base64 lacks the "data:image/..." prefix, the tool has no native way to know if the original file was a PNG, JPEG, or WebP. Selecting the correct format ensures the downloaded file has the correct extension.
Is my Base64 data uploaded to your servers?
No. This tool is built entirely on client-side web technologies. Your Base64 strings are parsed and decoded securely within your own web browser and are never sent to our servers.
Why does my decoded image look broken?
If your image appears broken, you likely pasted a Raw Base64 string but selected the incorrect image format (e.g. you selected PNG, but the data actually represents an AVIF image). Try switching formats!
