Get the best conversion results
Follow these expert tips to maximize quality and efficiency when converting PNG to ICO.
Use a Square PNG
For best results, start with a square PNG image (e.g., 512x512 or 256x256). Non-square images will be cropped or padded to fit.
Keep It Simple
Icons are displayed at small sizes (16x16 or 32x32). Avoid fine details, thin lines, or small text that will be invisible at low resolutions.
Use Transparency Wisely
PNG transparency is preserved in ICO. Use transparent backgrounds for favicons so they blend with browser tab colors.
Test at 16x16
Before finalizing, preview your icon at 16x16 pixels. If it is unrecognizable, simplify the design or increase contrast.
