Convert RAW to PNG — Free Online Converter

RAW to PNG converts camera sensor data into the Portable Network Graphics format — a lossless image format that preserves every pixel of the decoded RAW image without any compression artifacts. PNG was designed as the patent-free replacement for GIF and supports full 24-bit color (16.7 million colors), 8-bit alpha transparency, and gamma correction. It is the standard format for screenshots, web graphics, and any image where lossless quality matters.

Our converter uses Sharp to decode the RAW Bayer pattern data, apply demosaicing and tone mapping, then compress the result using PNG's DEFLATE algorithm — lossless compression that typically achieves 30-50% size reduction compared to raw pixel data.

PNG preserves the full quality of the decoded RAW image with no lossy compression. Every pixel, every color value is stored exactly as decoded from the sensor. This makes PNG ideal for photography when you need to preserve maximum detail for further editing, compositing, or printing. PNG's transparency support also enables cutout photography (product shots, headshots) with clean alpha channel edges. Web designers and graphic artists rely on PNG for images that must not show compression artifacts.
