PNG to ICO

Convert PNG to Windows ICO icon online free. Transform PNG images into ICO format for favicons.

Generate multi-resolution ICO favicon files directly from any PNG logo. This browser tool center-crops your image to a square, builds the standard icon sizes, and bundles them into a single ICO — transparency included — so your website, PWA, or Windows application gets a sharp, professional icon across every context.

PNG Transparency Carries Through

Unlike converting from JPG, starting with a PNG means your alpha channel is available. Transparent backgrounds stay transparent inside the ICO, so the icon blends cleanly against light browser chrome, dark themes, and desktop wallpapers alike. Make sure the logo's contrast works on multiple backgrounds before you ship it.

Building the Right Size Set

Favicons are consumed at 16 and 32 pixels; desktop shortcuts prefer 48; some installers look for 256. Rather than juggling separate files, the tool assembles these resolutions into one ICO. Your page and operating system each pull the size that suits them automatically.

  • 16px: browser tab indicator
  • 32px: address bar and Windows list view
  • 48px: desktop shortcut detail
  • 256px: high-DPI displays and application manifests

Preparing the Source Image

Square logos convert with no drama. Tall or wide marks need a center crop, which the tool applies by default — check the preview to confirm nothing important sits outside the frame. Starting from a vector export or a large PNG gives the downscaler clean data to work with at tiny sizes.

Legibility at 16 Pixels

Detail that reads beautifully at 300 pixels can vanish at 16. Strong silhouettes, limited color counts, and thick strokes survive reduction; fine serifs and photo textures do not. Preview the smallest size before finalizing, and keep a simplified variant of your mark on hand for favicon duty.

Installing Your New Icon

Reference the ICO from your document head, drop it in the project root so servers pick it up by convention, or assign it to a Windows shortcut. Since generation is local, unreleased brand marks stay private throughout the entire favicon pipeline.
