How to Convert EXR to PNG
Add your EXR file
Open UniConverter Desktop and add the EXR file from your computer. For a multi-file render set, add the supported EXR files you want to process in the same local conversion queue.
Choose PNG as the output
Choose PNG as the output format in UniConverter Desktop, then review the output options available for PNG in your installed version before starting the conversion.
Convert and save the PNG file
Start the EXR to PNG conversion and save the resulting PNG file to your chosen local folder. For a batch job, review the queue and output location before processing the full collection.
EXR vs PNG: HDR Production Data vs Portable Raster Output
OpenEXR is built for high-dynamic-range production images and can store floating-point pixels, arbitrary channels, multipart images, and deep data. PNG is a lossless raster format with integer samples up to 16 bits per channel, making it easier to use for previews, graphics, sharing, and general image workflows.

|---|---|---|
| File Extension | .exr | .png |
| Full Name | OpenEXR | Portable Network Graphics |
| Origin | Originally developed at Industrial Light & Magic and released as open source in 2003 | Standardized as Portable Network Graphics for portable, lossless raster images |
| Pixel / Sample Data | Supports 16-bit floating point, 32-bit floating point, and 32-bit unsigned integer channels | Uses integer sample depths from 1 to 16 bits; truecolor PNG uses 8- or 16-bit samples |
| Dynamic Range | Designed for high-dynamic-range and high-precision image data | Portable raster output with fixed integer samples rather than EXR-style floating-point HDR data |
| Channels | Can store arbitrary image channels, multipart data, and deep samples | Standard grayscale, RGB, indexed color, and optional alpha channel models |
| Compression | Supports multiple lossless and lossy compression methods | Lossless DEFLATE-based image compression |
| Common Use Cases | VFX, CGI rendering, compositing, HDR production, render passes | Previews, web graphics, screenshots, transparent graphics, editing, and sharing |
| Conversion Note | May contain data that has no direct PNG equivalent | A single PNG should not be assumed to preserve every EXR channel, floating-point value, or deep-data element |
Why Use UniConverter for EXR to PNG Conversion
Desktop EXR Input Support
Use UniConverter Desktop for EXR input. The browser converter does not accept EXR files, so the supported workflow is to convert local OpenEXR files on Windows or macOS.
Create PNG Copies for Broader Compatibility
Convert EXR renders to PNG when you need a simpler raster copy for previewing, presenting, editing, sharing, documentation, or workflows that do not require the full OpenEXR data model.
Understand EXR-to-PNG Data Differences
OpenEXR can store floating-point HDR values, arbitrary channels, multipart images, and deep data. A PNG output should not be assumed to preserve every EXR channel or production-data element, so review the converted result before replacing an EXR master.
Keep Render Files Local
Process supported EXR renders locally in UniConverter Desktop instead of sending them through the browser converter. This suits render folders, repeated conversion work, and desktop-based production pipelines.
Batch Convert Supported EXR Files
Add multiple supported EXR files to a local conversion queue, choose PNG as the target format, review the output location, and process the collection in one desktop workflow.
Keep EXR Masters for Production
Use PNG as a derivative copy when compatibility is the goal, but keep the original EXR master when you may still need floating-point HDR values, extra render channels, multipart data, or other production information later.
