Convert ICO to PSD — Free Online Converter

ICO (Windows Icon) stores multiple icon sizes in a single container, while PSD (Photoshop Document) is Adobe's layered editing format. Converting ICO to PSD extracts the icon image and places it in a Photoshop-compatible file that can be opened and edited in Adobe Photoshop, GIMP, Affinity Photo, and other PSD-compatible editors. This is useful when icon images need to be modified, enhanced, or incorporated into Photoshop-based design compositions.

The PSD format provides the editing foundation that ICO lacks -- you can add layers, apply effects, adjust colors, and combine the icon with other design elements in a full-featured image editor.

Redesigning or updating icons often requires working in Photoshop or similar raster editors. Converting the existing ICO to PSD provides a starting point with the current icon image as a base layer. Designers can then modify colors, add effects, adjust proportions, or completely redraw the icon while referencing the original.

PSD also serves as a bridge format for creative workflows. When icon images need to be composited with photographs, placed on mockup templates, or combined with other design elements, the PSD format provides the multi-layer editing environment needed for this work.

The largest resolution image from the ICO container is extracted and decoded to an RGBA pixel buffer. This buffer is written into a PSD file as a single Background layer (or a transparent layer if alpha data is present). The PSD maintains the icon's original pixel dimensions and color depth. Alpha transparency from the ICO is preserved as a layer mask or alpha channel in the PSD. ImageMagick handles the ICO decoding and PSD encoding with proper Photoshop-compatible layer structure.
