How to use Base64 to Image Converter
- Paste an image data URI or a raw Base64 image string, or Upload Base64 File to load a .txt or .base64 file - the preview renders as you type.
- Check the Dimensions and Image Format readouts against what you expected.
- Choose Image Format (PNG, JPEG or WebP) and Quality (for JPEG/WebP) to re-encode it, or a Preset Size such as 16x16 (Favicon) or 512x512 (Large) to scale it.
- Download Image saves the picture; Generate HTML puts an <img> tag in the Generated Code box for you to select and copy.
What Base64 to Image Converter actually does to your file
Picking a new format re-encodes through the browser canvas, which is lossy for JPEG and WebP even though the input was already an image - keep PNG when the source has flat colours or transparency. Bare Base64 with no prefix carries no type information, so the format named in the readout can differ from the real one; the picture still opens because browsers sniff content, but rename the download if you rely on the extension.
