JPG to ICO Converter

1. Upload one or more JPG files (up to 50 MB total).
2. Click 'Convert to ICO' — finishes in under 1 second per file.
3. Download ICO files individually, or grab all as a ZIP.

JPG is lossy and has no transparency — but if your source icon doesn't need transparency, JPG → ICO is a fine alternative to PNG. The ICO output will have a white background in transparent areas.

JPG is the most common image format for photographs, but ICO is required for favicons, Windows app icons, and desktop shortcuts. If you have a JPG logo, photo, or illustration that you want to use as an icon, converting to ICO provides the multi-size format that Windows and browsers expect. The trade-off: JPG has no transparency, so any areas that should be transparent in the icon will become white.

The converter reads the JPG image, resizes it to all standard ICO sizes (16×16, 32×32, 48×48, 64×64, 128×128, 256×256), and packages them into a single ICO file. Because JPG has no alpha channel, transparent areas (if any) become white in the ICO output.

• Creating favicons from a JPG logo (no transparency needed).
• Setting up Windows app icons from JPG images.
• Building Windows shortcuts with JPG-based icons.
• Preparing simple favicons without alpha channels.
• Creating app icons from JPG photos or logos.
• Building PWA icons from JPG assets.
• Standardizing favicons for CMS platforms.

The ICO file contains multiple sizes — Windows and browsers automatically select the best size for each context. For sharp favicons, use a JPG source of at least 256×256 so the downsampled sizes look crisp. Sources smaller than 48×48 will produce blurry ICOs.

• JPG has no transparency — the ICO will have a white background where transparency would be.
• JPG is lossy — the ICO output inherits any JPG compression artifacts.
• For transparent icons, use PNG → ICO instead.
• JPG sources smaller than 48×48 produce blurry ICOs.
• Icon text or fine details may appear soft after JPG compression.

• ICO opens natively on Windows (every version since 1990).
• Accepted by every browser for favicons.
• Works with Windows shortcuts, taskbar icons, and Explorer.
• Native import in image editors with icon support.
• Supported by every web browser for favicon use.

• Use a 256×256 or larger JPG source for crisp icons.
• For transparent icons, use PNG → ICO instead.
• Keep the JPG source if you plan to regenerate icons later.
• Multi-size ICO covers all common use cases automatically.
• Batch-convert multiple JPGs at once.

Favicon has white background where transparency is expected

JPG has no alpha channel. Convert your source to PNG first, then use PNG → ICO for transparent icons.

Icon looks blurry

The JPG source is too small. Use a JPG of at least 256×256 for best results.

Icon has compression artifacts

JPG's lossy compression shows around sharp edges. For crisp icons, use PNG → ICO instead.
