PNG to ICO — FAQ

What is an ICO file used for?+
ICO (icon) files are used for Windows application icons, browser favicons, and desktop shortcuts. They can contain multiple resolutions in a single file.
What resolution should my PNG be before converting to ICO?+
Use a square PNG at least 256×256 pixels. Common ICO sizes are 16×16, 32×32, 48×48, and 256×256. A high-resolution source lets the ICO look sharp at all sizes.
Will PNG transparency be preserved in the ICO?+
Yes. ICO supports full alpha transparency. Your transparent PNG logo or icon will convert correctly, preserving any transparent or semi-transparent areas.
Can I use the ICO as a website favicon?+
Yes. Place the file at /favicon.ico in your website root, or link it with <link rel="icon" href="/favicon.ico">. Modern browsers also accept PNG favicons directly.
What sizes are included in the ICO output?+
Picovert generates standard multi-size ICO files containing 16×16, 32×32, and 48×48 pixel variants — the sizes required for Windows icons and website favicons. Browsers and Windows automatically pick the best size from the ICO container.
What is the ideal source image size for a favicon?+
Use a square PNG at 256×256 pixels or larger for best results. Picovert automatically generates a multi-size ICO containing 16×16, 32×32, and 48×48 pixel variants from your source image. Avoid starting with a small image — upscaling to generate ICO produces blurry favicons.
