EXR Files Won't Open? Here's the Fix
You've rendered your scene and exported an EXR file, but your client can't open it. OpenEXR is the industry standard for VFX and 3D work, but most computers lack the software to display these high dynamic range images.
Converting to JPG solves this instantly. JPG opens on every device-Windows, Mac, phones, tablets-without any special software. Your client sees the image immediately.
How to Convert EXR to JPG
- Upload your EXR file - Drag and drop or click to select your OpenEXR image
- Confirm JPG output - JPG is selected as your universally compatible format
- Download your image - Get a JPG that opens anywhere, instantly
No plugins required. No After Effects or Nuke needed. Just upload and convert.
What is EXR?
OpenEXR is a high dynamic range (HDR) image format created by Industrial Light & Magic. It stores far more color and brightness information than standard images-up to 32 bits per channel compared to JPG's 8 bits.
This makes EXR essential for:
- VFX compositing - Preserves detail in shadows and highlights for color grading
- 3D rendering - Captures the full range from Blender, Maya, Cinema 4D, Houdini
- HDRI lighting - Environment maps need full dynamic range
- Film production - Industry standard for visual effects pipelines
In our testing, a typical 1080p EXR render from Blender averaged 12MB, while the converted JPG came out under 500KB-small enough to email directly.
When to Use JPG vs PNG
JPG is ideal for sharing photorealistic renders, product shots, and scene previews. The compression keeps file sizes manageable for email and web.
If your render has transparency (alpha channel), convert to PNG instead. PNG preserves transparent backgrounds while JPG does not-JPG will fill transparent areas with white or black.
For archival or continued editing, keep your original EXR. JPG is for final sharing, not as a working format.
Common Use Cases
Client Previews
Send render previews to clients who don't have professional software. JPG opens in any web browser or image viewer.
Portfolio and Social Media
Showcase your 3D work on Behance, ArtStation, or Instagram. These platforms accept JPG but not EXR.
Quick Reference Images
Create contact sheets or reference images from your render passes without launching compositing software.
What to Expect
EXR files contain high dynamic range data that exceeds what monitors can display. When converting to JPG, this range gets compressed to standard dynamic range (SDR). Extremely bright highlights and deep shadows will clip to white or black.
This is normal and expected. The resulting JPG represents what viewers would see on a typical monitor. For critical color work, tone map your EXR in professional software first, then convert the result.
