ICO to PNG Converter

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

PNG preserves transparency from ICO icons, unlike JPG. If you're extracting a favicon with a transparent background, PNG is the correct target — the alpha channel survives intact.

ICO files are Windows icon containers storing multiple sizes of an icon — often with transparent backgrounds. When you need to use an icon as a regular image (in design work, websites, or documents), PNG is the ideal target: it preserves ICO's transparency, produces lossless output, and opens in every modern editor. The converter extracts the largest embedded size by default for best quality.

The converter reads the ICO file, identifies the largest embedded icon size, decodes that image, and writes it as PNG. The output is lossless — every pixel of the decoded icon is preserved exactly, including the alpha channel. No re-compression loss occurs.

• Extracting favicons with transparent backgrounds.
• Converting app icons for design work.
• Preparing icons for use in Figma, Sketch, or Adobe XD.
• Creating icon assets for websites and apps.
• Making icons available as high-quality images for non-technical users.
• Preparing icons for print or large-format display.
• Converting legacy Windows icons to modern PNG format.

PNG output is lossless — every pixel of the extracted ICO icon is preserved exactly, including transparency. This makes PNG the best target when you need to preserve the icon's exact appearance for editing or high-quality display.

• Only the largest embedded size is extracted — other sizes discarded.
• Very small icons (16×16) may appear pixelated when enlarged.
• ICO animations (rare) are not preserved.
• Some ICO variants (CUR cursor files) may have limited compatibility.
• Very old PNG-unsupported software may not open the output.

• PNG opens natively on every OS and in every image editor.
• Universal browser support since 1996.
• Native import in Photoshop, GIMP, Affinity, Illustrator, Figma, Sketch.
• Accepted by every CMS, marketplace, and design tool.
• Ideal for web design, app design, and asset management.

• PNG preserves ICO transparency — best for icons with alpha.
• The largest icon size is extracted by default.
• For further editing, keep the PNG — lossless format.
• For smaller files without transparency, use ICO → JPG.
• Batch-convert up to 50 MB at once.

PNG output is small and pixelated when enlarged

ICO icons are typically 16×16 to 256×256. Enlarging shows pixelation. Extract from the original source if available.

Transparency is preserved but appears black in some viewers

Some viewers show transparent areas as black by default. This is a viewer setting, not a file issue.

PNG is much larger than the ICO

Expected — ICO compresses more aggressively for icons. PNG is lossless and preserves exact quality.
