Convert HDR images (EXR) online for free
The converter easily converts your EXR images to various formats - free and online. No Adobe Photoshop or other Raster Image software needed.
The converter also works in reverse, so you can convert other "High Dynamic Range Image" formats to EXR without using software like Adobe Photoshop or a similar tool.
The .EXR file is an open-source, high dynamic range (HDR) raster image format developed by Industrial Light & Magic. Technically known as OpenEXR, it stores 16-bit and 32-bit floating-point pixels. This provides extreme color accuracy and dynamic range, making it the industry standard for 3D rendering, digital compositing, and visual effects (VFX).
To natively open and edit .EXR files, you need heavyweight professional software like Adobe Photoshop, Blender, or Nuke. The format supports multiple layers, lossy and lossless compression algorithms, and deep image data.
However, .EXR files are highly impractical for everyday use. They suffer from massive file sizes, often exceeding hundreds of megabytes per frame. They are completely unsupported by web browsers, standard image viewers, and mobile devices. Without professional tonemapping, they look completely washed out or overly dark to the average user. Sending an .EXR file to a client or uploading it to a website is a guaranteed failure without prior conversion.
For web use and quick sharing, convert to JPG or WEBP (note: extreme brights and darks will be permanently compressed into an 8-bit color space). For high-quality archiving or print, convert to TIFF or PNG. Drag and drop your file here to analyze and convert it - free, online, and without installing software.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our EXR converter.
