Paste a Base64 string to instantly decode and view the hidden image. Convert code back into PNG, JPG, or GIF files directly in your browser.
Ever found a massive string of random characters in a CSS file or a JSON response and wondered what it was? Chances are, it's a Base64 encoded image. Our Base64 Image Decoder is designed to help developers and designers quickly turn that text back into a viewable image. Whether you need to extract a logo from a stylesheet or verify an image sent via an API, this tool handles the conversion instantly.
Base64 encoding is a way to represent binary data (like images) in an ASCII string format. This is incredibly useful for embedding small images directly into HTML or CSS to reduce the number of HTTP requests. However, it makes the image unreadable to the human eye.
Using a Base64 to PNG or Base64 to JPG converter allows you to:
We built this tool to be the fastest and most secure way to view Base64 strings. Unlike other tools that upload your data to a server, our decoder works 100% client-side. This means your images never leave your computer, making it safe for sensitive or private assets.
It supports all modern formats, including WebP and SVG. If you're working with complex data structures, you might also find our JSON Formatter helpful for cleaning up the API responses that contain these strings.
data:image/...).If the image is too large for your needs after decoding, you can easily resize it using our Image Resizer.
This is a Data URI scheme. It tells the browser that the following data is an image, specifically in PNG format, and that it is encoded using Base64. Our tool can handle strings with or without this prefix.
Yes! As long as the original file was a GIF, the Base64 string will contain all the animation data. When you decode it here, the preview will show the animation, and you can download it as a .gif file.
This usually happens if the string is truncated (cut off) or contains invalid characters. Ensure you have copied the entire string. Also, make sure the string actually represents an image and not just plain text or a PDF.
