What happens when you convert EXR to PNG?

EXR channels & deep data

An EXR may carry named auxiliary channels, multipart images or deep samples, beyond a flat RGB image. A rendered PNG copy is not an equivalent EXR working file. Channel selection, deep compositing and numeric mapping need explicit engine support; no export of every channel or depth sample is implemented.

Multiple source images

EXR can contain multiple image representations with different roles. These are not automatically a timed animation. Selecting an image, preserving a collection or creating several outputs needs explicit engine support; neither a first-image choice nor an all-images export is implemented.

HDR display encoding

The source can carry HDR information and PNG has HDR-capable variants. Working radiometric values and display-referred HDR are different representations. Range, primaries, transfer function and signalling must be mapped explicitly; the future engine may instead produce SDR. HDR preservation is not promised by format support.

Lossless sample storage

PNG compression is lossless. Palette conversion, resizing or reducing bit depth before encoding can still discard information. Animation is the APNG extension included in the third edition. PNG can store its supported image samples without lossy compression. This applies after rendering and sample conversion: it does not guarantee preservation of source precision, colour space or document structure, and cannot undo earlier losses.

Is EXR → PNG right for you?

Good choice when

PNG fits your delivery use: Screenshots & transparent graphics.
You need a rendered view of selected EXR image data.
You can choose the source image or part needed for delivery.
You need HDR-capable delivery and can validate its encoding and colour signalling.

Probably not when

You need every auxiliary channel or deep sample for compositing.
You require a complete collection, page set or multipart round trip.
You require guaranteed scene-linear values or HDR appearance.
You assume format-level alpha support guarantees matching transparent edges.

EXR to PNG conversion details

EXR channels & deep data: An EXR may carry named auxiliary channels, multipart images or deep samples, beyond a flat RGB image. A rendered PNG copy is not an equivalent EXR working file. Channel selection, deep compositing and numeric mapping need explicit engine support; no export of every channel or depth sample is implemented.

HDR display encoding: The source can carry HDR information and PNG has HDR-capable variants. Working radiometric values and display-referred HDR are different representations. Range, primaries, transfer function and signalling must be mapped explicitly; the future engine may instead produce SDR. HDR preservation is not promised by format support.
Transparency representation: Both format profiles allow transparency, but this does not promise identical alpha representation. Source variants, target channel precision and alpha interpretation matter. The future encoder must explicitly carry or convert transparency; merely choosing PNG guarantees no alpha transfer.
Lossless sample storage: PNG compression is lossless. Palette conversion, resizing or reducing bit depth before encoding can still discard information. Animation is the APNG extension included in the third edition. PNG can store its supported image samples without lossy compression. This applies after rendering and sample conversion: it does not guarantee preservation of source precision, colour space or document structure, and cannot undo earlier losses.
Sample precision & colour: Source and target sample models can differ in precision, channel layout, colour space and transfer function. Lossless compression only preserves the samples actually encoded; a precision reduction or colour conversion can already change them. The future engine defines numeric mapping, orientation and colour conversion; canonical depth facts are listed below where available.
Metadata & colour: Format support does not guarantee that an export preserves metadata or colour profiles. Retention and colour handling depend on the future converter; its engine is not implemented yet.
Compression: EXR: Lossy & lossless → PNG: Lossless EXR: EXR supports lossy and lossless codecs. Choose one for the sample types and required precision; .exr alone does not guarantee exact channel preservation. PNG: PNG compression is lossless. Palette conversion, resizing or reducing bit depth before encoding can still discard information. Animation is the APNG extension included in the third edition.
Transparency: EXR: Yes → PNG: Yes
Animation: EXR: No → PNG: Yes
Colour depth: EXR: HALF 16 / FLOAT 32 / UINT 32 → PNG: 1–16 bits/sample
HDR: EXR: Floating-point working values → PNG: Third-edition signalling
Multiple images: EXR: Multipart
Dimensions: Pixel dimensions, page geometry, rendering resolution, resizing and orientation need explicit converter policies. The future engine has not defined them yet.
Metadata: EXR: Typed header attributes, Chromaticities → PNG: Exif, ICC, Text. Which fields are copied, rewritten or omitted will depend on the future engine; retention is not implemented yet.

Common questions

Will all EXR channels and deep samples survive?

Will every source image be exported?

Will HDR automatically survive in PNG?

Are bit depth and colour values guaranteed to match?

Source and target sample models can differ in precision, channel layout, colour space and transfer function. Lossless compression only preserves the samples actually encoded; a precision reduction or colour conversion can already change them. The future engine defines numeric mapping, orientation and colour conversion; canonical depth facts are listed below where available.

Will metadata and colour profiles be retained?
