Convert Base64 to an Image
Paste Base64 image data and preview or download the decoded image locally.
Direct Answer
Use the Base64 to Image Converter when you have a Base64 string or data URI representing an image and need to view it as an actual picture or download it as a file, such as when debugging an API response, database field, or email template.
What this tool expects as input
This tool takes text that represents image bytes and turns it back into an actual rendered image.
- A full data URI, such as one starting with data:image/png;base64, followed by the encoded data
- A raw Base64 string, in which case the image format may need to be specified separately
- Base64 image data copied from an API JSON response
- Base64 values pulled from a database field stored as text
- Inline images extracted from HTML email templates or browser devtools network payloads
How this differs from Image to Base64
These two tools perform opposite conversions, and it helps to be clear about which direction you need.
- This tool goes from text, Base64 or a data URI, to a rendered and downloadable image file
- The Image to Base64 Converter goes the other way, from an uploaded image file to Base64 text
- Use this tool when you already have the encoded text and want to see or save the picture it represents
- Use the other tool when you have a picture file and need the text representation to embed in CSS, HTML, or JSON

Frequently Asked Questions
What format should my Base64 input be in?
It can be either a full data URI, such as data:image/png;base64, followed by the encoded content, or a raw Base64 string on its own. If you provide a raw string without the data URI prefix, the image format may need to be specified separately so the bytes can be interpreted correctly.
Why did the image fail to render or show as broken?
This usually happens when the Base64 string was truncated or corrupted during copying, the MIME type prefix is missing or incorrect, stray whitespace or line breaks ended up inside the encoded data, or the underlying bytes simply aren't a valid image format.
Is this the same as the Image to Base64 Converter?
No, they're inverse operations. This tool converts Base64 text into a viewable image, while the Image to Base64 Converter converts an uploaded image file into Base64 text. Which one you need depends on whether you're starting from encoded text or from an actual image file.
Can I download the resulting image as a file?
Yes, once the image renders successfully you can save it locally as a file, typically in the format indicated by the original data, such as PNG or JPEG.
Why do I need to know the image format beforehand for a raw Base64 string?
The MIME type tells the browser how to interpret the decoded byte stream as a specific image format. Without it, or with the wrong one specified, the same bytes can fail to render or display incorrectly.
Is my Base64 image data uploaded to a server when I use this tool?
No. The decoding and rendering happen locally in your browser, so the data you paste stays on your device and isn't uploaded anywhere.
Why does my data URI start with data:image/png;base64?
That prefix is part of the data URI standard and tells browsers and applications the MIME type and encoding method before the actual encoded payload begins, so the following text is interpreted correctly as an image rather than plain text.
Can I convert Base64 that represents a PDF or another non-image file here?
No, this tool is built specifically for image formats. Non-image Base64 data may decode without an error but will not render as a picture, since the tool expects the bytes to represent a valid image.
