What happens when you convert PNG to BMP?

Animation becomes a still

Still image output. Animated files use only the first frame; animation is not preserved.

HDR to SDR

HDR is rendered to SDR using exposure and Reinhard tone mapping.

Encoding mode

BMP may be uncompressed or use a header-selected encoding. Alpha is header-dependent; 32 bits alone do not establish transparency support in the receiving application. The output uses the implemented still-image encoder; file size depends on the pixels and format.

Portable Network Graphics

Compression: LosslessTransparency: YesMetadata: Exif, ICC, Text

Lossless raster images with precise edges and optional transparency. The PNG standard also defines APNG animation.

BMP

Target

BMP

Windows Bitmap

Compression: Depends on variantTransparency: YesMetadata: DIB header, ICC (V5)

Windows raster storage with several DIB header versions. Simple uncompressed pixels are common, but alpha and compression vary.

Is PNG → BMP right for you?

Good choice when

BMP fits your delivery use: Windows bitmap interchange.
You want a still illustration from an animated source.
You need an SDR delivery copy and can review its tone mapping.
You need a transparency-capable destination and will check its supported variant.

Probably not when

Motion, frame timing or loop behaviour must survive.
You need the original HDR range for relighting or grading.
You assume format-level alpha support guarantees matching transparent edges.
You need a guaranteed output file size or archival pixel equality. Encoder settings do not guarantee either.

PNG to BMP conversion details

Animation becomes a still: Still image output. Animated files use only the first frame; animation is not preserved.
HDR to SDR: HDR is rendered to SDR using exposure and Reinhard tone mapping.
Transparency representation: The implemented target supports alpha. Display-pixel processing can round translucent samples; archival sample equality is not promised.
Encoding mode: BMP may be uncompressed or use a header-selected encoding. Alpha is header-dependent; 32 bits alone do not establish transparency support in the receiving application. The output uses the implemented still-image encoder; file size depends on the pixels and format.
Sample precision & colour: Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
Metadata & colour: Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
Compression: PNG: Lossless → BMP: Depends on variant 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. BMP: BMP may be uncompressed or use a header-selected encoding. Alpha is header-dependent; 32 bits alone do not establish transparency support in the receiving application.
Transparency: Transparency is replaced with white by default. Change the background in Advanced options.
Animation: Still image output. Animated files use only the first frame; animation is not preserved.
Colour depth: PNG: 1–16 bits/sample → BMP: 1 / 4 / 8 / 16 / 24 / 32 bpp
HDR: PNG: Third-edition signalling
Dimensions: Rendered image dimensions are retained within the converter limits; this tool does not offer resizing. Orientation handling depends on the source decoder.
Metadata: Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.

Common questions

Will the output keep animation?

Still image output. Animated files use only the first frame; animation is not preserved.

How will HDR brightness be mapped?

HDR is rendered to SDR using exposure and Reinhard tone mapping.

Which compression mode will BMP use?

Are bit depth and colour values guaranteed to match?

Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.

Will metadata and colour profiles be retained?
