Base64 to Image Decoder
Convert Base64 strings into visual images instantly. This tool takes your encoded data (Data URIs) and renders them back into their original visual format—supporting PNG, JPG, GIF, SVG, and WebP.
How to use the Base64 Image Decoder
- Paste your string: Input the Base64 code (with or without the
data:image/...;base64, prefix).
- Instant Preview: The tool automatically detects the image format and renders a preview.
- Save/Download: Once decoded, you can right-click the image to save it to your device.
Common Use Cases for Image Decoding
- Email Template Debugging: Many modern email clients embed images as Base64 strings to ensure they load offline. Use this tool to verify those images.
- Web Development: Inspect “Data URIs” used in CSS or HTML to reduce HTTP requests.
- Database Inspection: If your application stores small icons or profile pictures as BLOBs/Base64 in a database, this tool helps you verify the content without writing a script.
- Forensics & CTF: Useful for extracting hidden images from log files or network captures during security challenges.
Unlike traditional converters that upload your string to a server—which can be slow and risky for private images—this decoder works 100% client-side.
Developer Fact: Because the decoding happens in your browser’s memory, we never see your images, and there is zero lag regardless of your internet speed.
Our decoder is compatible with all standard web image formats:
- Raster Images: .jpg, .png, .gif, .bmp
- Vector Graphics: .svg (renders as a scalable preview)
- Modern Formats: .webp and .avif
