What happens when you convert PSD to ICO?

Rendered composition

Uses the saved merged RGB/grayscale image. Layers are not recomposited; 16-bit, CMYK and PSB are not supported.

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.

Is PSD → ICO right for you?

Good choice when

ICO fits your delivery use: Application icons & favicons.
You need a rendered delivery copy of the composition.
You need an SDR delivery copy and can review its tone mapping.
You need an icon resource for a compatible application.

Probably not when

You must keep masks, layer effects or editable text.
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.

PSD to ICO conversion details

Rendered composition: Uses the saved merged RGB/grayscale image. Layers are not recomposited; 16-bit, CMYK and PSB are not supported.
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: PSD: Lossless → ICO: Depends on variant PSD: PSD channel compression is lossless, but a document may contain previously lossy source assets. Composite rendering and layer editing are different capabilities; this page does not claim portable animation playback. 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.
Colour depth: PSD: 8 / 16 / 32 bits/channel
HDR: PSD: 32-bit workflows
Layers: PSD: Layers & masks
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 editable PSD layers survive?

Uses the saved merged RGB/grayscale image. Layers are not recomposited; 16-bit, CMYK and PSB are not supported.

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?
