ICO Converterv1.0.0

Create a ready-to-use favicon.ico and Windows icon from any common image format. Select standard icon sizes and color depth to produce a single ICO file that includes multiple resolutions for sharp results across browsers, operating systems, and high-DPI displays.

Generate icons for websites, desktop software, and file explorers. Improve brand consistency by packaging 16×16, 32×32, 48×48, 64×64, 128×128, and 256×256 entries with true-color transparency when needed.

Produce a multi-size ICO in a few steps. Use a square source image for the sharpest results.

• Upload or drag and drop a PNG, JPEG, GIF, BMP, or WebP under 4 MB.
• Select icon sizes to include: 16, 32, 48, 64, 128, and optionally 256 pixels.
• Choose 32-bit color for true color with alpha transparency, or choose 8-bit for a small file with a palette.
• Click Convert to generate and download your favicon.ico.
• Reconvert with different sizes or bit depth to balance quality and file size.
• Select how non-square images are handled:
  • Crop to square: fills the icon by trimming the edges of the image. Best for centered artwork and standard favicons.
  • Pad to square (transparent): preserves the full image by adding transparent margins. Best for logos or shapes that must not be cropped.

Notes: 256×256 requires 32-bit color. Multi-size ICO files bundle several resolutions into one file. Browsers and operating systems automatically select the closest size. The default fit mode is Crop to square for sharp, full icons; switch to Pad to square if you prefer to keep the entire image visible.

Support common icon workflows with fast, consistent output.

• Create a crisp website favicon by packaging 16, 32, and 48 pixel sizes.
• Ship Windows application icons by bundling 16–256 pixel entries with 32-bit transparency.
• Standardize desktop and folder icons across teams and devices.
• Convert a brand mark to an ICO for installers, launchers, and admin dashboards.
• Experiment with 8-bit versus 32-bit output to reduce size while preserving clarity.

Generate a lightweight website favicon by selecting 16, 32, and 48 pixel sizes with 32-bit color. Improve sharpness on high-DPI screens by including 64 and 128. Package a full set for Windows installers by adding 256 with 32-bit alpha transparency for smooth edges. Optimize for older systems by exporting an 8-bit version with a palette when the artwork uses simple flat colors. Replace scattered single-size icons by generating one multi-size ICO that browsers and operating systems can read consistently. Create branded folder icons for a design project by converting a company logo into 64 and 128 pixel entries. Prepare large icons by bundling 48, 128, and 256 so high-density displays choose suitable sizes. Convert a square social media profile image into a favicon.ico for personal blogs to maintain consistent branding across platforms.

Include 16, 32, and 48 for broad browser support. Add 64 and 128 for high-DPI displays. Add 256 for Windows application icons and installers.

Choose 8-bit for very small files when the artwork uses flat colors and minimal shading. Choose 32-bit for logos with gradients, shadows, or semi-transparent edges.

Square inputs produce proportional icons at all sizes. Non-square images require padding or cropping, which can reduce visual quality.
