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 WEBP to ICO?

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

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

How It Works

Drop your WEBP filesDrag multiple .webp files onto the drop zone, or click Browse Files. Thumbnails generate immediately using the browser's native WEBP decoder.

Click Convert to ICOThe browser decodes each WEBP natively to pixel data; 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. WEBP files are never sent to any server — they stay in your browser's memory from load to download. This is especially important for proprietary graphics, brand assets, or 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.

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.

Does the ICO support transparency from WEBP?▼

Yes — the ICO frames are encoded as 32-bit RGBA PNG, which supports full alpha channel transparency. If your WEBP source has transparent areas, they will be preserved in the ICO output.

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_webp_to_ico_YYYYMMDDHHMM.zip using your local time — for example dataconversioncenter_webp_to_ico_202603081200.zip.
