How to convert PNG to EXR
- Add your .PNG file - drop it in the box above or click to browse.
- Convert it to .EXR in a few seconds.
- Download your new .EXR file.
What to expect
- No true HDR is gained; 8-bit PNG data simply moves into a floating-point container.
- EXR files are generally much larger than the source PNG.
- PNG transparency can be kept as an alpha channel; EXR is a passive image with no executable content.
Frequently asked questions
Does converting PNG to EXR improve the dynamic range?
No.
EXR is a floating-point HDR format, but an 8-bit PNG has no extra brightness data to recover, so the conversion stores the same tones in a float container without adding real dynamic range.Why convert a PNG to EXR?
EXR is the standard in film and VFX pipelines, so PNG source art is converted to EXR to fit into compositing and rendering workflows (Blender, Nuke-style tools) that expect floating-point, multi-channel images.
What opens an EXR file?
Blender, GIMP and Krita open EXR for free. To share it as an ordinary picture you export back to PNG or JPG, applying tone-mapping if the values exceed the 8-bit range.
Will the file get bigger?
Yes. EXR stores floating-point, potentially multi-channel data, so an EXR is typically much larger than the compact lossless PNG it came from.
