Base64 to Image
Decode Base64 strings back to images — preview, download, and inspect Base64-encoded image data.
About Base64 to Image
This tool reverses the Base64 encoding process — converting a Base64 string back to a viewable and downloadable image. It accepts both full data URIs (data:image/png;base64,...) and raw Base64 strings without the prefix. This is useful for debugging API responses that contain Base64-encoded images, inspecting image data URIs found in CSS or HTML, and downloading images embedded in source code.
FAQ
How do I tell if a Base64 string is a valid image?
Valid Base64-encoded images start with specific bytes: PNG images always start with iVBOR, JPEG images start with /9j/, GIF with R0lG, and WebP with UklG when decoded. If your Base64 string starts with data:image/, the MIME type is included in the prefix.
