XCF to ICO

How to Convert XCF to ICO Online

1. Upload Your XCF File: Drag and drop or click "Add Files" to load GIMP project files. Multi-layer XCFs, XCFs with channels, paths, masks, and selections all decode to a flattened still that the ICO encoder can use. Batch is supported, so you can drop in several .xcf projects and pull an icon from each.
2. Pick the Icon Size: ICO output uses the icon-sized resolution presets — 256p, 192p, 180p, 128p, 64p, 48p, 32p, 24p, or 16p (the standard Windows icon ladder). 32×32 is the long-standing taskbar default; 256×256 is the maximum a Windows ICO container will render in Explorer's "Extra large" view, introduced with Windows Vista.
3. Set Quality, Bit Depth, and Color Palette (Optional): Pick a quality preset (Highest, Very High, High, Medium, Low, Very Low, Lowest) — Very High is the default and stays sharp at every Windows display scale. Choose an image bit depth — 8-bit (Recommended) for normal app icons, 1-bit (Black & White) for a silhouette icon, or 16-bit (High Precision) for photographic detail. Optionally set a color palette size (2, 4, 8, 16, 32, 64, 128, or 256 colors) to keep the file tiny for flat-color logos.
4. Convert and Download: Click Convert. The XCF flattens and re-encodes to ICO inside your browser session, then downloads to your device — no GIMP install required, no sign-up, no watermark.

Why Convert XCF to ICO?

XCF is GIMP's native project format. It preserves layers, channels, paths, masks, and selection state — everything needed to keep editing a design — but only GIMP can open it. ICO is the opposite end of the spectrum: a tiny Windows icon container that holds one or more square stills (16, 32, 48, 64, 128, 256 px) for the taskbar, desktop, Explorer, tray, and browser favicons. Converting XCF → ICO flattens the editable icon design straight into a Windows-native asset without the JPG/PNG intermediate step. Common reasons people pull an ICO from a GIMP project:

• Application and installer icons for Windows builds — .exe resources still take ICO with embedded 16, 32, 48, 64, 128, and 256 px sizes. A layered GIMP design exports cleanly to a 256 px ICO for the highest-resolution layer in that bundle, then downscales for the smaller sizes.
• Browser favicons designed in GIMP — <link rel="icon" href="favicon.ico"> still expects an ICO. A GIMP project sized to 32×32 (or a multi-size layered design) goes straight to ICO without a PNG round-trip.
• Custom desktop and folder icons — Right-click a folder, Properties → Customize → Change Icon expects an .ico file. Use a GIMP-designed icon for that working directory's folder so it stands out at a glance in Explorer.
• Tray and Start Menu shortcut icons — System tray icons (16 / 24 / 32 px) need ICO. A GIMP design with a bold silhouette and high contrast reads cleanly even at 16 px in the notification area.
• Game launcher and emulator shortcut icons — Steam non-Steam shortcuts, RetroArch playlists, and Lutris menus all read ICO. A GIMP-painted box-art mockup or custom logo works as the source.
• Replacing a generic icon on a packed .exe — Tools like Resource Hacker and rcedit accept ICO; a GIMP project gives you a fully editable brand asset to mine for the icon at every size.

If you want to keep the lossless source pixels around for editing later, convert through XCF to PNG first, then build the ICO. For a flat shareable image without the icon constraints, XCF to JPG is the smaller path.

XCF vs ICO — Format Comparison

ICO Resolution Quick Guide

A typical Windows ICO bundle ships at 16, 32, 48, and 256. Favicons usually only need 32×32 (or 16/32/48 combined). Pick the size that matches where you'll actually use the icon.

Frequently Asked Questions

Are GIMP layers preserved in the ICO?

No. ICO is a flat raster format — it holds one or more single-layer images at fixed icon sizes, with no concept of GIMP layers, masks, paths, or selections. The converter flattens all visible layers using the same compositing GIMP would use on export. If you need to keep editing the layered design later, keep a copy of the original .xcf alongside the exported ICO.

What happens to transparent areas in my XCF?

Transparency carries through. ICO supports a 1-bit transparency mask and, in PNG-encoded ICOs (the format Windows Vista and later use for 256 px icons), full 8-bit alpha. Transparent and semi-transparent pixels in your GIMP design are preserved so the icon can sit over the desktop wallpaper, taskbar, or a folder thumbnail without a hard rectangular background.

What icon size should I export?

For a browser favicon, 32×32 is the most widely supported single size, with 16×16 and 48×48 as common companion sizes in a multi-image ICO. For a Windows app or installer, ship 16, 32, 48, 64, 128, and 256 so Explorer can pick the right size for every view (list, small, medium, large, extra-large). For a single desktop or folder shortcut, 256×256 is enough — Windows will downscale it for smaller views.

Should I pick 8-bit, 16-bit, or 1-bit depth?

8-bit (Recommended) is the right call for almost every modern app icon — it gives you 256 colors per channel, matches what Windows expects, and keeps file size small. 16-bit (High Precision) preserves more gradient detail and is useful when the source is a wide-gamut GIMP project and the icon is going to be displayed at 256 px. 1-bit (Black & White) gives you a monochrome silhouette icon — smallest file, retro aesthetic, and the lookalike a lot of system-tray apps still use.

Why does my 16×16 icon look blurry?

Detail that fits comfortably in a 1024 px GIMP canvas turns into mush at 16×16. Thin strokes and small text downscale to a smear. For tiny sizes, design the source so the icon shape reads at 16 px — bold silhouette, no fine text, high contrast against the background. If you need a sharp 16×16, design that size separately in GIMP rather than relying on a downscale of the 256 px version.

How do I make a multi-size ICO bundle for a Windows installer?

Generate the highest-resolution ICO first (256p) from the XCF, then run additional conversions at 128p, 64p, 48p, 32p, 24p, and 16p. Bundle the individual ICO files into a single multi-size ICO with a tool that supports it (IcoFX, or magick convert with multiple input PNGs). For a plain favicon a single 32×32 ICO is enough — most modern browsers also accept the source PNG via <link rel="icon" type="image/png">, so converting through XCF to PNG is a viable alternative.

Do I need GIMP installed to convert XCF to ICO?

No. The converter parses the XCF format directly and renders the flattened result to ICO entirely in your browser session — no GIMP, no Photoshop, no plugins. This is useful when you receive an .xcf from a designer and just want to build the Windows icon without installing a 200 MB image editor.

Can I batch-convert several XCF projects into icons at once?

Yes. Drop in multiple .xcf files and each one converts to its own ICO with the same size, quality, and bit-depth settings — handy for an app suite where every project file becomes the icon for a corresponding .exe or shortcut. Output downloads individually or as a ZIP archive.

Why does my GIMP design look slightly different in the ICO?

GIMP's working canvas displays unflattened layers with live blending modes; the ICO is the composited result downscaled to a fixed icon size. Differences are usually subtle (slight softening on hard edges, snapping of semi-transparent pixels to the alpha mask). For a pixel-perfect match at 16×16 or 32×32, design at the target size in GIMP rather than downscaling from a 1024 px canvas.
