Base64 to Image
Paste a Base64 string or data URI and get the image back — preview it and download. On your device, no upload, no sign-up.
🔒 Decoded on your device · 0 bytes uploaded
How it works
Your browser decodes the Base64 text into image bytes on your device and renders it — nothing is uploaded. A full data URI keeps its type; raw Base64 with no header is assumed to be PNG.
About decoding Base64
Base64 is a way to carry binary data as plain text. Developers often store small images this way in HTML, CSS, JSON or logs; this tool turns that text back into a real image file you can save.
Frequently asked questions
How do I decode Base64 to an image?
Paste a Base64 string or a full data URI and press Decode. The image previews and you can download it. It runs in your browser.
What image formats are supported?
Whatever the data encodes — PNG, JPG, GIF, WebP and more. Raw Base64 with no header is treated as PNG.
Is anything uploaded?
No. Decoding happens on your device and nothing is sent to a server.
What is a BASE64 file?
Base64 encodes binary data (like an image) as plain text so it can be embedded directly in HTML, CSS, or JSON. It makes data about a third larger but lets files travel as text.
