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

What happens when you convert AVIF to ICO?
HDR to SDR
HDR is rendered to SDR using exposure and Reinhard tone mapping.
Icon packaging
Creates one square icon. The image is fitted inside it without stretching.
Encoding mode
ICO compression depends on the embedded image payload. Multiple sizes are alternatives, not animation frames; transparency handling differs between old masks and alpha-capable images. The output uses the implemented still-image encoder; file size depends on the pixels and format.

Good choice when
- ICO fits your delivery use: Application icons & favicons.
- You want a still illustration from an animated source.
- You need an SDR delivery copy and can review its tone mapping.
- You need an icon resource for a compatible application.
Probably not when
- Motion, frame timing or loop behaviour must survive.
- You need the original HDR range for relighting or grading.
- You need automatic icon design or guaranteed multi-size packaging.
- You assume format-level alpha support guarantees matching transparent edges.
AVIF to ICO 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.
- Icon packaging
- Creates one square icon. The image is fitted inside it without stretching.
- Transparency representation
- The implemented target supports alpha. Display-pixel processing can round translucent samples; archival sample equality is not promised.
- Encoding mode
- ICO compression depends on the embedded image payload. Multiple sizes are alternatives, not animation frames; transparency handling differs between old masks and alpha-capable images. 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
- AVIF: Lossy & lossless → ICO: Depends on variant AVIF: AVIF can use lossy or lossless AV1 coding. Chroma subsampling, RGB↔YUV conversion and reduced bit depth can change source values even when the AV1 coding stage is lossless. ICO: ICO compression depends on the embedded image payload. Multiple sizes are alternatives, not animation frames; transparency handling differs between old masks and alpha-capable images.
- 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
- AVIF: 8 / 10 / 12 bits
- HDR
- AVIF: Optional; colour properties
- Multiple images
- ICO: Alternative icon sizes
- Dimensions
- Creates one square icon. The image is fitted inside it without stretching.
- 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.
Will ICO automatically create all icon sizes?
Creates one square icon. The image is fitted inside it without stretching.
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.
