Base64 to Image Decoder

How to Use Base64 to Image

1. Paste the Base64 string into the left textarea. A full data:image/png;base64,... URI works, as does the raw Base64 body alone.
2. Click Decode — the image appears on the right with its dimensions and detected format.
3. Download — the suggested filename uses the detected extension (e.g. image.png).

Supported input

Any Base64-encoded image: PNG, JPG, WebP, GIF, BMP, SVG. The decoder reads the MIME type from the data URI header when present; if you paste raw Base64, it falls back to PNG.
