Add your EXR file
Drop one or more .exr files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
EXR to PNG
Converting a .exr image to .png re-encodes the pixels for a different balance of size, quality, and support. Free, private, and validated — the file never leaves your browser.

Converting a .exr image to .png re-encodes the pixels for a different balance of size, quality, and support. An .exr file is an OpenEXR image: a high-dynamic-range raster format that stores scene-referred light values as floating-point numbers rather than display-ready 8-bit codes. It is the working image format of visual effects and animation, where a frame has to survive repeated relighting, grading, and compositing without the highlights and shadows being thrown away.
A .png file is a losslessly compressed raster image with full 8-bit alpha transparency, making it the standard choice for graphics that must stay pixel-perfect. Screenshots, logos, UI assets, and diagrams are the classic .png territory, since sharp edges and flat color survive without compression artifacts. For this route the practical draw is perfectly lossless, so files can be opened and re-saved indefinitely and true 8-bit (or 16-bit) alpha channel — balanced against photographic content produces files several times larger than JPEG or WebP, which is worth knowing before you commit a large batch.
Why convert EXR to PNG?
The practical trigger for this conversion is usually a mismatch: with .exr, files are large, and the lossless codecs help far less than they do on 8-bit imagery. Switching to .png buys you perfectly lossless, so files can be opened and re-saved indefinitely, which is why it is the better fit for screenshots and screen recordings exported as stills. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
EXR vs PNG at a glance
| Aspect | OpenEXR image (.exr) | PNG image (.png) |
|---|---|---|
| Format type | Lossless — every pixel or sample is preserved exactly | Lossless — every pixel or sample is preserved exactly |
| How it stores data | pixels are 16-bit half float, 32-bit float, or 32-bit unsigned integer, one value per channel, with no fixed 0-1 ceiling | uses DEFLATE compression preceded by per-scanline prediction filters (None, Sub, Up, Average, Paeth) |
| Strongest at | rendered frames handed between a renderer, a compositor, and a grading suite | screenshots and screen recordings exported as stills |
| Weak spot | files are large, and the lossless codecs help far less than they do on 8-bit imagery | photographic content produces files several times larger than JPEG or WebP |
| Metadata | metadata lives in typed header attributes: chromaticities, white luminance, capture date, owner, camera transform matrices and free-form strings. There is no EXIF or ID3 block, and this converter's raster outputs do not carry the header attributes across | text metadata lives in tEXt/iTXt chunks and XMP can be embedded there; standardized EXIF arrived late via the 2017 eXIf chunk, so many tools still drop EXIF when writing PNG |
Pick PNG as the output
Select .png in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if PNG is selectable, the route is real and validated.
Convert on your device
Press Convert. Decoding and re-encoding happen on your device using the browser's native image pipeline and hand-tuned encoders.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid PNG file. Outputs keep the original filename with the .png extension.
EXR to PNG questions, answered
Will converting EXR to PNG lose quality?
Since exr is lossless-oriented and png is lossless-oriented, the conversion preserves the source content exactly as stored; no additional compression pass is applied beyond what .png itself requires.
Is it private to convert EXR files here?
Yes — the .exr file is processed inside your browser tab and never uploaded. Decoding and re-encoding happen on your device using the browser's native image pipeline and hand-tuned encoders. Close the tab and the file is gone from memory.
Where will the PNG file work?
Every modern browser has rendered PNG with full alpha since Internet Explorer 7 fixed its transparency bug in 2006, and native OS support is universal on Windows, macOS, Linux, iOS, and Android. It is also the required format in many contexts, such as iOS app icons and favicon fallbacks.
Will the PNG file be bigger or smaller than my EXR?
It depends on the content: uses DEFLATE compression preceded by per-scanline prediction filters (None, Sub, Up, Average, Paeth). Convert one representative file first and compare before batch-processing a large set.
What happens to the metadata in my EXR file?
In .exr, metadata lives in typed header attributes: chromaticities, white luminance, capture date, owner, camera transform matrices and free-form strings. There is no EXIF or ID3 block, and this converter's raster outputs do not carry the header attributes across. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
