Transform your professional camera raw shots into standard, lightweight PNG files instantly with batch support.
DNG (Digital Negative) is a royalty-free, publicly documented raw image format created by Adobe and launched on September 27, 2004. Unlike proprietary raw formats such as CR2 or NEF, DNG's specification is openly published, which is why Adobe designed it as an archival format: a DNG file is more likely to remain readable decades from now than a camera-specific format tied to one manufacturer's software. Many cameras can shoot directly in DNG, and Adobe also provides a free converter that repackages other raw formats into DNG. Structurally, it's built on the TIFF 6.0 standard and is compatible with TIFF/EP.
PNG (Portable Network Graphics) is a lossless raster format released in the mid-1990s as a royalty-free successor to GIF, after a licensing dispute over the LZW compression algorithm. It compresses images with the DEFLATE algorithm, the same method used by ZIP archives, so every pixel is preserved exactly with no generation loss on repeated saves. PNG also supports a full 8-bit alpha channel for smooth, partial transparency, unlike GIF's binary on/off transparency. These properties make it the standard choice for screenshots, logos, icons, and any graphic with sharp edges, flat colors, or text that needs to stay perfectly crisp.
RAW formats like Adobe DNG capture uncompressed sensor data resulting in massive file sizes that standard web browsers, gallery apps, and social media platforms cannot read natively. Converting them to PNG unlocks immediate compatibility, making your high-resolution photography ready for web sharing, editing, and archiving.
