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 GIF to ICO?

ICO is the standard format for Windows application icons and browser favicons. If you have a logo, animated badge, or simple graphic as a GIF that you want to use as an icon, converting to ICO is the right step.

Can I convert multiple GIF 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 GIF decoding and ICO encoding happens entirely in your browser using JavaScript. Your files 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.

What This Tool Does

Converts GIF images — logos, animated badges, sprites, and simple graphics — to ICO format entirely in your browser. Each ICO output contains six embedded PNG frames at standard icon sizes (16×16, 32×32, 48×48, 64×64, 128×128, and 256×256 pixels). GIF decoding uses native browser Canvas APIs — no server upload, no account, no file size limits imposed by a backend.

Who This Is For

Web developers who need a favicon from an existing GIF logo or icon
Windows app developers who need an ICO file for application icons
Designers converting GIF graphics or sprites into multi-size icon assets
Anyone who needs a quick ICO from a GIF without installing software

Example: Input: logo.gif → Output: logo.ico (multi-size icon, ready for favicon or Windows app use)

How It Works

Drop your GIF filesDrag one or more .gif files onto the drop zone, or click Browse Files. Thumbnails generate immediately using the browser's native GIF rendering.

Click Convert to ICOThe browser decodes each GIF to pixel data via Canvas; the ICO encoder scales to six sizes and builds a standards-compliant ICO blob in memory.

Download your ICOsDownload files individually or check "Download as ZIP" for a single timestamped archive. App resets after export.

🔒 Privacy & Security

All decoding and encoding runs entirely in your browser. GIF files are never sent to any server — they stay in your browser's memory from load to download. This is especially important for proprietary logos, branded assets, and client work.

Frequently Asked Questions

What sizes does the output ICO contain?▼

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.

What happens to animated GIFs?▼

Only the first frame of an animated GIF is used for the ICO output. ICO is a static format and does not support animation. The first frame is typically the clearest representation of the graphic.

Can I convert multiple files at once?▼

Yes — drop up to 25 or more files at once. The tool processes them sequentially, shows per-file status badges, and lets you download all ICOs individually or as a single timestamped ZIP.

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.

What is the ZIP file named?▼

The ZIP is named dataconversioncenter_gif_to_ico_YYYYMMDDHHMM.zip using your local time — for example dataconversioncenter_gif_to_ico_202603071800.zip.
