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

What happens when you convert PNG to PAM?
HDR to SDR
HDR is rendered to SDR using exposure and Reinhard tone mapping.
Lossless sample storage
Netpbm stores these samples without compression. Reducing colour, thresholding or changing maxval can still lose information before storage; text and binary representations change the layout, not its image meaning. PAM 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.

Good choice when
- PAM fits your delivery use: Channel-aware image pipelines.
- 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 expect lossless encoding to restore lost details or editing structure.
PNG to PAM 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.
- Lossless sample storage
- Netpbm stores these samples without compression. Reducing colour, thresholding or changing maxval can still lose information before storage; text and binary representations change the layout, not its image meaning. PAM 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
- 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 → PAM: Uncompressed 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. PAM: Netpbm stores these samples without compression. Reducing colour, thresholding or changing maxval can still lose information before storage; text and binary representations change the layout, not its image meaning.
- 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 → PAM: maxval up to 65535
- 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.
Does lossless output mean an unchanged source?
Netpbm stores these samples without compression. Reducing colour, thresholding or changing maxval can still lose information before storage; text and binary representations change the layout, not its image meaning. PAM 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.
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?
Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
