What sizes does the ICO file contain?

Each ICO output contains six embedded PNG frames: 16×16, 32×32, 48×48, 64×64, 128×128, and 256×256 pixels. Modern Windows and browsers select the best size automatically.

Why convert HEIC to ICO?

ICO is the standard format for Windows application icons and browser favicons. If you have a photo or logo as a HEIC file that you want to use as an icon, converting to ICO is the right step.

Can I convert multiple HEIC files at once?

Yes — this tool supports batch conversion. Drop up to 25+ files at once, monitor per-file status, then download individually or as a single ZIP archive.

Does my data get uploaded to a server?

Never. All HEIC decoding and ICO encoding happens entirely in your browser using JavaScript. Your photos never leave your device.

What software opens ICO files?

ICO files open natively in Windows Explorer (as icons), web browsers (as favicons), GIMP, Photoshop (with a plugin), and most professional image editors.

Each ICO file contains six PNG frames: 16×16, 32×32, 48×48, 64×64, 128×128, and 256×256 pixels. Windows and browsers automatically select the most appropriate size for the context.

Can I use the ICO as a favicon?▼

Yes — ICO is the original favicon format. Rename the output to favicon.ico and place it in your website root. All browsers will use it automatically, selecting the most appropriate embedded size.

Can I convert multiple files at once?▼

Does the ICO support transparency?▼

Yes — the ICO frames are encoded as 32-bit RGBA PNG, which supports full alpha channel transparency. If your source HEIC has a transparent background (uncommon), it will be preserved.

Is this tool free with no limits?▼

Yes — completely free with no file size limits, no per-conversion limits, and no account required. Processing happens in your browser so we never see your files.
