About Base64 to Image
The Base64 to Image converter decodes a Base64 string back into a viewable, downloadable image. Paste a full data URL or just the raw Base64 — the tool auto-detects PNG, JPEG, GIF, WebP, SVG and BMP from the encoded file signature.
It's the counterpart to our Image to Base64 tool, and handy when you find embedded images in HTML, CSS, JSON or API responses and need to see or save the actual picture.
Decoding happens instantly in your browser; the image data is never transmitted anywhere.

Frequently Asked Questions
Why does my Base64 string fail to decode?
Common causes: whitespace or line breaks inside the string (the tool strips these), a truncated copy that cuts off the end, or data that isn't an image (like an encoded PDF). Make sure you copied the complete string.
How does the tool know the image format?
Every image format starts with characteristic magic bytes, which survive Base64 encoding as a recognizable prefix — e.g. PNG data always starts with 'iVBORw0KGgo'.
Is the Base64 to Image converter free?
Yes, the Base64 to Image converter is completely free with no usage limits. No signup, no account and no installation required.
Is my data safe?
Yes. All processing happens locally in your browser using JavaScript — nothing you type is uploaded or stored on our servers.
