Pro Tips
- •Each page is scaled to fit within a square canvas of the chosen size, centered with white padding if the page isn't already square
- •The generated ICO file embeds a modern PNG image, which is supported by Windows Vista and later, as well as most icon viewers
- •Smaller sizes (16-32px) are best for taskbar or file icons, while larger sizes (128-256px) suit desktop shortcuts and app icons
- •The whole file is rendered locally in your browser - nothing is uploaded anywhere

Frequently Asked Questions
What happens if my PDF page isn't square?
The page is scaled to fit within the square icon size while preserving its aspect ratio, and centered with white padding filling any remaining space.
Will this ICO file work on older versions of Windows?
The file uses a PNG-based icon entry, which is supported starting with Windows Vista. For compatibility with very old Windows versions, a classic BMP-based ICO would be needed instead.
Which size should I choose?
Use 16 or 32px for small UI icons like file associations, 48-64px for desktop icons, and 128-256px for high-resolution app icons and modern displays.
Is my PDF uploaded to a server?
No. The entire file is read, rendered, and encoded locally in your browser. Your document never leaves your device.
Can one ICO file contain multiple sizes?
This tool generates one size per ICO file, matching your selection. Professional icon tools can combine multiple sizes into a single multi-resolution ICO if needed.
