About the EXR Format
EXR (OpenEXR) is a high dynamic range image format developed by Industrial Light & Magic (ILM). It is the industry standard in visual effects, animation, and film production for storing images with a wide luminance range. EXR supports 16-bit and 32-bit floating-point channels, multiple compression methods (including lossless), arbitrary image channels, and multi-part files. The format excels at preserving subtle detail in both shadows and highlights, making it indispensable for compositing, colour grading, and any workflow that demands the highest fidelity in image data.
Features
Near-Zero CO₂
Server-based converters upload your file, process it remotely, and send it back — consuming network and data-centre energy on every request. WebConverter runs entirely on your device, so the only energy used is your local CPU. No data transfer, no server electricity.
Install for Offline Use
WebConverter works offline as a Progressive Web App. Click "Add to Home Screen" on mobile or the install button in your browser's address bar. Once installed, you can convert files without any internet connection.
