Convert EXR to HDR
Fast, free, and secure EXR to HDR conversion. No registration required.
Xonvert turns exr into hdr using WebAssembly — the same technology that powers AAA browser games. Both OpenEXR Image and HDR Image are image formats, but they differ in approach: OpenEXR Image prioritizes 32-bit float HDR with multiple channels for compositing while HDR Image focuses on captures extreme brightness ranges for realistic lighting. Professionals in graphic design, photography, and marketing rely on this specific conversion regularly. Xonvert uses the same powerful libraries that professional desktop applications rely on — FFmpeg, libvips, and more.
EXR vs HDR: Why Convert?
There are strong reasons to convert EXR to HDR:
No vendor lock-in: HDR Image is supported across all major platforms, giving you freedom to use any software you prefer.
Print shop acceptance: Professional print services commonly accept HDR Image, making this conversion essential for anyone preparing files for physical production.
Speed of delivery: HDR Image files maintain full quality while being optimized for efficient sharing.
Search engine benefits: For web content, HDR Image is widely recognized by search engines, potentially improving your content's discoverability.
Privacy advantage: Converting locally with Xonvert means sensitive OpenEXR Image files never leave your device during the HDR Image conversion.

How HDR Handles EXR Data
File size after conversion depends on the content complexity and your quality settings. HDR Image preserves all data losslessly, so output size depends on the content's inherent compressibility. Use HDR for 3D environment lighting and skybox creation For the best results, start with the highest quality OpenEXR Image source file available. HDR Image is known for captures extreme brightness ranges for realistic lighting. This means your converted output will benefit from HDR Image's core strengths. Meanwhile, the original OpenEXR Image's advantage of 32-bit float HDR with multiple channels for compositing may not fully carry over, depending on HDR Image's capabilities.
Converting between image formats is one of the most common file operations. When moving from OpenEXR Image to HDR Image, key considerations include color depth preservation, transparency support, and compression artifacts. Both formats preserve images losslessly, so this conversion is purely a container change with zero quality impact.
The EXR to HDR conversion applies format-appropriate algorithms to ensure maximum data fidelity. Supports 16-bit half-float and 32-bit full-float per channel

EXR to HDR Conversion: Your Questions Answered
How does the EXR to HDR conversion work technically?▼
Xonvert uses WebAssembly-compiled libraries to decode your EXR file in-browser, process the image data, and re-encode it as HDR. All processing happens on your device's CPU.
What happens to my files after conversion?▼
Nothing — your files exist only in your browser's memory during conversion. Once you close the page, all data is cleared. No files are stored anywhere.
What is EXR format?▼
OpenEXR Image is High dynamic range image format for visual effects. It is primarily used for VFX compositing, HDR photography and 3D rendering output. Developed by ILM for film visual effects production
Will the conversion strip my EXIF or metadata?▼
Xonvert preserves metadata (EXIF, XMP, ID3, etc.) when the target HDR format supports it. You can optionally strip metadata in the settings for smaller, cleaner output files.
Does the conversion preserve metadata?▼
Xonvert preserves compatible metadata fields when converting between formats. Some format-specific metadata may not carry over if the target format doesn't support it.
Can I share the converted HDR file directly?▼
Yes. After conversion, you can download the HDR file and share it via email, messaging apps, cloud storage, or any other method you prefer.
Does converting EXR to HDR change the resolution?▼
No. The original resolution is preserved by default. You can optionally resize in the settings panel if you need different dimensions.
