Convert image files with our easy to use and free tool. Our tool lets you upload a HDR (Radiance RGBE) file and from this, create a new image saved in the PNG (Portable Network Graphics) format that you can then download and edit/use within image file editors or use for high definition printing applications. Our conversion tool can also batch convert multiple HDR image files, up to 25 files at a time can be converted.
Along with converting HDR image files to PNG, our tool allows you to also adjust the image with some simple effects such as applying a greyscale filter to the image. These additional options are available within the Options tab. Along with Greyscale, you can also mirror/flip the image if needed. For single HDR file uploads you will also see options to resize and rotate your image.
Here are 2 simple steps to convert your HDR to PNG.
First click the "Upload..." button, select your HDR file to upload. Select any configuration options. When the HDR to PNG conversion has completed, you can download your PNG file straight away.
We aim to process all HDR to PNG conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.
We aim to create the most accurate conversions with our tools. Our tools are under constant development with new features and improvements being added every week.

The HDR format is an image format that captures a wide range of brightness and color information. It achieves this by combining multiple exposures or frames to preserve detail in extreme lighting conditions.
As HDR technology continues to advance, it plays a crucial role in enhancing the visual quality and realism of digital content, making it an important part of the entertainment and photography industries.
The PNG graphics file format is a commonly used format for storing 2D images which can be highly compressed by the use of a palette if the image has a sufficiently low number of colors (256 colors in general). The PNG file is then further compressed using the DEFLATE compression algorithm to ensure small file sizes that are fast to download.
PNG files are seen as the logical successor to the GIF image file format and was devised in the mid-1990's as a superior format to GIF. PNG files are generally used for company logos, icons and other non-photographic image content. Saving a digital photo in the PNG format will create a much larger file than an equivalent JPG image hence the PNG format being unsuitable for most digital photo content.
