Free Base64 to Image Converter
Paste a Base64 string or data URI to preview the image and download it as a file. Runs privately in your browser — nothing is uploaded.
What is a Base64 to Image converter?
This tool reverses Base64 image encoding: it takes an encoded string — or a full data URI — and turns it back into an actual image you can view and save. It's useful when you find a Base64 image embedded in HTML, CSS, JSON, or an API response and need to see or extract the original file.
Paste in the string, preview the result, and download it in its detected format (PNG, JPG, GIF, SVG, WebP, and more). Everything runs locally in your browser, so the image data never leaves your device.
Frequently asked questions
How do I convert Base64 back to an image?
Paste your Base64 string or full data URI into the box and click Preview. The image renders instantly and you can download it as a file.
Do I need the full data URI or just the Base64?
Either works. If you paste a full 'data:image/...;base64,...' URI, the correct format and file extension are detected. If you paste raw Base64 with no prefix, it's treated as a PNG.
Why won't my string preview?
The string may be incomplete, contain invalid characters, or not actually be image data. Make sure you copied the entire Base64 value without modification.
Is this private?
Yes. Decoding and preview happen entirely in your browser — nothing is uploaded or stored.
