About the Formats
🎬 What is EXR (OpenEXR)?
EXR (OpenEXR) is a high dynamic range (HDR) image format developed by Industrial Light & Magic for visual effects and CGI work. It supports 16‑bit and 32‑bit floating point pixels, multiple layers, deep data, and alpha channels. EXR is the industry standard for professional 3D rendering, VFX, and compositing.

PNG (Portable Network Graphics) is a lossless raster format created in 1996. It supports full alpha transparency, 24‑bit color, and is widely used for web graphics, logos, and screenshots. PNG is the standard for lossless images with transparency.

When to Convert EXR to PNG
🎨 VFX & CGI Previews
Send quick previews of your HDR renders to clients or team members. PNG files are universally viewable and preserve transparency.
💡 Need layers? EXR to TIFF →🌐 Web Portfolios
Showcase your 3D artwork online. PNG supports transparency and lossless quality, perfect for portfolio sites.
💡 Smaller web version: PNG to WebP →🎮 Game Development
Use PNG for textures and UI elements derived from HDR sources. PNG is widely supported in game engines.
💡 Keep HDR: JPG to EXR →📂 Archiving
Create PNG versions of your EXR files for easy archiving and quick access without specialized software.
💡 Reverse: PNG to EXR →Format Comparison
| Format | EXR | PNG |
|---|---|---|
| Compression | Lossless | Lossless |
| Transparency | Yes | Yes |
| File Size | Larger | Larger |
Need to preserve full HDR data? Keep the original EXR. For sharing and web, EXR to PNG is ideal. For smaller file sizes, try EXR to JPG (lossy, no transparency).
💡 Pro Tips
- EXR contains high dynamic range data. Our tone mapping converts it to a standard 8‑bit PNG that looks natural on any screen.
- If your EXR has an alpha channel, enable transparency preservation to keep it in the PNG.
- Adjust exposure and gamma in advanced settings to fine‑tune the look of your render.
- Convert in batch mode — upload multiple EXRs and download all PNGs as a ZIP archive.
- We strip metadata by default for privacy, but you can keep EXIF by toggling the option (rare in EXR).
- For final delivery, always keep the original EXR master. Use PNG for previews and web sharing.
How EXR to PNG Conversion Works
EXR (OpenEXR) stores pixels as floating‑point values, capturing a wide dynamic range. PNG uses 8‑bit integers and lossless compression. To convert, we first decode the EXR data, then apply tone mapping to compress the HDR into the 8‑bit range while preserving visual detail. If the EXR contains an alpha channel, it is preserved in the PNG.
The result is a lossless PNG file that faithfully represents your HDR render on standard displays. All processing is done in memory, and files are permanently deleted after 10 minutes.
EXR vs PNG: Key Differences
Dynamic range: EXR supports HDR (floating point); PNG is limited to 8‑bit standard range.
Use cases: EXR for professional VFX, CGI, and compositing; PNG for web, sharing, and editing.
Transparency: Both support alpha channels, making PNG a great choice for previews of HDR work.
When to Choose PNG Over EXR
Choose PNG when you need a lossless, universally compatible version of your HDR image for web portfolios, client previews, or quick editing. PNG’s transparency support makes it ideal for overlays and UI elements derived from VFX work.
If you need to go back to HDR, keep your original EXR. Our PNG to EXR converter can create an EXR from a PNG, but HDR data cannot be recovered.
