How to Convert EXR to PNG

Converting an EXR to PNG in the Online EXR Viewer takes three steps:

1. Open the file — drag your .exr onto the viewer, or use the file picker. It decodes right in the page.
2. Adjust exposure and gamma — dial in a preview that looks correct on your monitor (see below for why this matters).
3. Click export PNG — the current view, tone-mapped exactly as displayed, is saved as a standard 8-bit PNG.

That's it — no signup, no plan, no watermark.

Why Exposure and Gamma Matter Before You Convert

EXR stores scene-linear HDR (high-dynamic-range) float data — pixel values aren't capped at 1.0 the way PNG's 8-bit channels are capped at 255. A bright highlight might be stored as 4.0 or 20.0, representing real light intensity rather than a display value.

PNG can't represent any of that — it's an SDR (standard-dynamic-range) format. So converting EXR to PNG always involves a tone-mapping decision: which HDR values become white (255), which become black (0), and how the range in between is compressed. That decision is exactly what the exposure and gamma sliders control.

If you skip this step and just export at default settings, values above 1.0 get hard-clipped to solid white and shadow detail can get crushed. Nudging exposure down before export recovers highlight detail; nudging gamma adjusts the midtone curve. Get more of the theory in Why Your EXR Looks Too Dark or Washed Out.

The Privacy Advantage of a Local Converter

Most "EXR to PNG" converters you'll find online — Convertio, AnyConv, and similar file-conversion sites — work by uploading your file to their servers, converting it there, and sending back a download link. That means your render, your source file, whatever it is, sits on someone else's server, even briefly.

The Online EXR Viewer decodes the file entirely in your browser with JavaScript. Nothing is ever sent anywhere — the conversion happens on your own machine, which matters if the file is a client render, an unreleased project, or anything else you'd rather not hand to a third-party server.

Limitations to Know

• Single-layer, scanline EXR — the viewer is built for standard scanline EXR files. Deep or multi-part EXR files with many render layers aren't supported for conversion.
• PNG is 8-bit SDR, always — no matter how the source EXR is stored, the exported PNG is capped at 256 levels per channel. It's a snapshot of the tone-mapped view, not a lossless copy of the HDR data. If you need to preserve full float precision, keep the original EXR — don't treat the PNG as a backup.
