Data URL to Image Viewer and Converter

The Data URL to Image Viewer and Converter helps you understand and reuse an image that has been embedded as text. Paste a complete data:image string from HTML, CSS, JSON, an API response, an email template, or a development log. The tool validates the structure, asks the browser to decode the payload, and shows the resulting picture only when the value is a real supported image. Invalid or incomplete text stays in the editor so you can correct it without disruptive alerts.

Once decoded, the viewer reports the media type, natural pixel dimensions, encoded character count, and an estimated decoded byte size. Those details are useful when auditing unexpectedly large inline assets or identifying whether an unfamiliar string represents PNG, JPEG, WebP, GIF, AVIF, SVG, BMP, or another image type supported by the current browser. The preview sits on a checkerboard surface so transparent areas remain visible in both the light and dark website themes.

You can download the original decoded payload with an appropriate extension or convert the visible image to PNG, JPEG, or WebP. PNG is a good choice for transparency, interface graphics, and lossless output. JPEG creates smaller photographic files but replaces transparency with a white background. WebP offers efficient modern compression and can preserve transparency. A quality control is available for JPEG and WebP so you can balance detail against file size before downloading the result.

SVG export places the decoded source into a portable SVG image wrapper with the correct width, height, and viewBox. Like the companion image-to-SVG tool, this does not perform vector tracing; raster pixels remain embedded inside the document. If the pasted Data URL already contains SVG, downloading the original preserves that source. Canvas-based conversion of animated GIFs or animated WebP files exports the currently decoded frame rather than rebuilding the animation.

All decoding and conversion runs locally in the browser. The tool does not need to upload the pasted image for ordinary viewing or export. Remember that Base64 is an encoding format, not a security layer: anyone who receives the Data URL can decode its contents. For production websites, use inline images selectively. Small icons and self-contained examples can benefit from Data URLs, while large images generally load, cache, and update more efficiently as separate optimized files.
