What is a HDR file?
HDR stands for High Dynamic Range and refers to image formats that preserve a wide range of luminance levels. HDR files are often used in lighting simulations, video games, and visual effects to capture lighting beyond standard display capabilities.
The most common HDR format is Radiance HDR, storing 32-bit floating-point values per color channel.
How to open HDR files
HDR files can be opened with image editors like Adobe Photoshop, GIMP, and Luminance HDR. They’re also supported by game engines and rendering software like Unity and Unreal Engine.
To convert HDR to a standard format like JPG or PNG, AnyConv makes it easy to process even large files online.

What is a PNG file?
PNG stands for Portable Network Graphics. It’s a popular raster image format developed as an open alternative to GIF. Released in 1996, PNG supports lossless compression, which means the image quality is preserved when the file is saved.
PNG is ideal for graphics that need transparency, sharp edges, or repeated editing — such as logos, icons, and screenshots. Unlike JPG, it retains full detail but usually results in larger file sizes.
How to open PNG files
PNG files are supported by nearly all operating systems and applications. You can open them using default image viewers on Windows, macOS, Linux, Android, and iOS.
Web browsers, design software like Adobe Photoshop, and online tools such as AnyConv also handle PNG files without issues.
