Supports PNG with transparency, JPG, WebP, and SVG vector graphics
The Windows Icon (.ico) file format is a container capable of holding multiple icon frames at different pixel resolutions within a single file. When Windows or a browser displays an .ico file, it automatically selects the sharpest frame for the current display scaling factor.
NexoPixel generates standard PNG-compressed ICO files containing 16×16, 32×32, 48×48, and 256×256 frames, ensuring sharp rendering on standard displays and High-DPI screens.
Because icons require square aspect ratios (1:1), NexoPixel allows you to choose between 'Fit Entire Image' (preserving full logo aspect ratio centered with transparent padding) and 'Fill / Square Crop' (cropping to fill the entire square).
Alpha transparency from your source PNG or SVG is strictly preserved across every embedded frame.
NexoPixel constructs the binary ICO container directly in your browser using native JavaScript binary arrays. No files are uploaded to any external server.
