What the pros know

Pro Tip

Send a client the HTML or PNG preview of a render rather than the EXR. They can open it without any software.

Common Mistake

Replacing the EXR with the preview in a pipeline. The preview has lost the precision the EXR was saved for.

Best For

Sharing or checking a render from Blender, Nuke or another tool on a device without that software.

Not Recommended

Not for compositing or grading. Keep the original EXR.

Previewing an EXR render without compositing software

OpenEXR is the format renderers and compositing tools use for high-precision images, and no browser displays it. We convert the EXR to a PNG and put it in the HTML page, so you can see the render on any device. It's a preview: PNG can't hold EXR's extra precision and brightness range, so those are reduced to a normal image. EXR to HTML used to fail; it works now.
